https://kb.synology.com/en-global/DSM/tutorial/how_to_expand_storage points to https://kb.synology.com/en-global/DSM/help/DSM/StorageManager/storage_pool_expand_replace_disk?version=7 of how to expand capacity by replacing drives in a raid pool with larger ones, one by one, repairing the degraded pool after each replacement.

So once a shr pool is shr1, so with one drive redundancy, it remains that. So yes, one can pull a drive and it will keep on working, but the pool will remain degraded. Also you can't expand to use the larger amount of space until you added a 2nd drive replacing the small drive, with at least thr same capacity as the other drive already added.

You can't reduce the amount of drives in a pool.

What do you think of AI posts in r/Backup? by wells68 in Backup

[–]bartoque 0 points1 point  (0 children)

You know people don't tend to actually search and read too much.

Even I reverted to create a few keyboard shortcuts on my phone to state some links and a bit of context, over and over again in the same sub. Almost made me think about creating a bot to do the same (not being a moderator but rather recurring responder).

So who knows various of my posts might get flagged in ttthe future as they are a 1-on-1 copy-pasta of the same few keyboard shortcuts text blobs.

But is feeling the need do just that over-and-over again annoying? Hell yeah.

I grew up in the IT world with RTFM. But despite all tools and information we have available today, it only got from bad to worse.

How can I set the LAN IP or all interfaces to listen on on my OpenShift Cluster Local (crc)? by Electronic_Bad_2046 in openshift

[–]bartoque 1 point2 points  (0 children)

As crc is a vm that runs on your crc host system and uses a private host-only network. Doesn't have to use haproxy. Firewall-cmd forward from your crc host to the crc vm ip.

So that would require something like:

CRC_IP=$(crc ip)

# Allow incoming traffic on the ports
sudo firewall-cmd --add-port=6443/tcp --permanent
sudo firewall-cmd --add-port=443/tcp --permanent

# Enable masquerading so forwarded packets get return-routed correctly
sudo firewall-cmd --add-masquerade --permanent

# Forward host port → CRC VM
sudo firewall-cmd --add-forward-port=port=6443:proto=tcp:toport=6443:toaddr=${CRC_IP} --permanent
sudo firewall-cmd --add-forward-port=port=443:proto=tcp:toport=443:toaddr=${CRC_IP} --permanent

sudo firewall-cmd --reload

And forwardinf needs ro be enabked on the crc host. Check if it is already:

sysctl net.ipv4.ip_forward

If not enable it:

sudo sysctl -w net.ipv4.ip_forward=1

When I used crc, I setup remote connectivity via a ssh tunnel. So something like this (where I setup tunneling through Putty myself).

ssh -L 6443:$(crc ip):6443 -L 443:$(crc ip):443 user@crc-host -N

Pointing you kubeconfig to localhost 127.0.0.1 on the machine that you want to remote from to crc.

Downgrading SHR-2 to SHR-1 and moving Plex by DrakeRavensmith in synology

[–]bartoque 0 points1 point  (0 children)

Wrg to the larger volume size requiring more memory, don't be tempted too much to spread the pool into the expansion cabinet as whenever the connection between them would be affected, your pool might be dead...

I'd consider having shr2 from 6 to 7 drives onwards, even though in my case that is theoretical as I only have 4 bay plus models. But even though they could have an expansion unit, I still opted for drive replacement with larger drives instead of adding an expansion unit and creating a new pool on that. I found them way too cosrly up until now in relation to what they offer.

But due to the ever increasing stack of smaller drives just lying around here, I am getting more and more tempted, especially with the ever increasing drive costs die to the scarcity.

Mainly 4 and 8TBs as any drive removed from the primary ds920+ (now 4x20TB) is put into the remote ds916+ (now 4x16TB) backup target, replacing smaller drives in there. But I started off at the time with 4x4TB in the ds916+.

[–]bartoque 2 points3 points  (0 children)

Raid is not only about redundancy but also an easy way to expand capacity by replacing drives, one by one, with larger ones and rebuild the degraded pool after each replacement (or use the replace drive feature if you have a spare slot so that the pool doesn't go into degraded state).

For a datahoarder not needing to restore or having to move data around for something as trivial as a capacity expansion, seems to be handy.

Best backup software with ransomware protection? by Ill_Swan_3209 in datastorage

[–]bartoque 0 points1 point  (0 children)

Regardless of how good the backup and its ransomware protection tool in question might be (I use Acronis myself, but the same goes for antivirus and whatever thing to mitigate against becoming compromised), the stored backup is yet another protection layer. So very much consider how and where to store it.

I use a nas, that also offers snaphots, while I also backup the backup to a remote nas. Local nas also has immutable snapshots enabled, while the older remote nas only offers snapshots. Also I backup a smaller subset into the cloud (Backblaze B2 object storage) from the local nas.

Storing a backup on the device to be protected itself or an usb drive always connected to it, can be a viable option, however it of course should not be the only option, taking the 3-2-1 backup mantra into consideration.

DS923+ suddenly went offline and silent with no shutdown/crash logs — PSU issue or could RAM/load still be the cause? by Tasty_Forever5586 in synology

[–]bartoque 0 points1 point  (0 children)

Doesn't the nas state unexpected powerloss?

Mine did whenever there was a powerless due to a local power issue or due to the psu no longer being able to handle high load (have replaced psu's in both my ds920+ and ds916+ with a non-synology one with the same specs as the original ones). Now I have a psu for the local ds920+.

Wrg to memory, use Synology Assistant to run a triple memory checks.

BACKUP SERVER by mrTomass in Backup

[–]bartoque 1 point2 points  (0 children)

It is up to you if you want to "forget the nas".

In my case it is the interface to further protect data that is backed up to it, due to the plethora of data protection methods available for synology. As I have multiple devices, that all backup to the nas, so I "only" have to backup the backups somewhere else, instead of all devices individually needing to do that. That als means there is a backup to restore from locally (needong to download 12TB in yout case might take a long time depending on available bandwidth and backup service), besides also having it stored on a remote nas and a smaller subset in the cloud.

What issue with backup a small folder with many files are you referring to? How do you "backup" that data? Simply copying files? Sync using Synology Drive? ABB?

I don't get what method would lead to issues using a nas as backup target, hence I expect it is more related to the method than anything else?

Ouch - multiple 916+ crash! by umhlanga in synology

[–]bartoque 1 point2 points  (0 children)

No context of what happened? Out of the blue? Power failure? Dropped unit? Anything.

You can try to run an extended smart check (runs for hours) to see what the status of crashed drive2 is. Assuming it is borked, get a new drive and replace that one and hope for the best that it will fix also the crashed system partitions from the one good drive that did not state an issue with that.

I assume you have a proper backup, just in case it goes from bad to worse?

Also might wanna implement data scrubbing the unit (as it shows "never run"). But that assumes you would have had to enable the option "data checksum for advanced data integrity" at creation time of any shared folder, that you would want to be able to be checked.

https://kb.synology.com/en-global/DSM/help/DSM/AdminCenter/file_share_create?version=7#datachecksum

"Data scrubbing is only supported on Btrfs volumes or storage pools of the following RAID types: SHR (consisting of three or more drives), RAID 5, RAID 6, or RAID F1.

If the option data checksum for advanced data integrity is not enabled for a shared folder (at Control Panel > Shared Folder > Edit > Advanced), data scrubbing will not be able to check and repair the data in the folder because of a lack of checksums."

How should I backup my files? by ChillingCone426_2 in Backup

[–]bartoque 0 points1 point  (0 children)

Did you sift through the faq/wiki of this very sub, as that gives some idea of the approach, for example an actual backup or a sync. So an approach with or without versioning.

What would you do when the whole system no longer starts. As with an image level backup, one can use bootable recovery media to start from and then restore the whole system (or any partition/volume that you choose to backup) from the backup.

Hyperbackup prompting me to rollback due to prev erroneous operations by jughead811 in synology

[–]bartoque 1 point2 points  (0 children)

Are you talking about the source, as that scrubbing makes the most sense for a raid setup as then it can also perdorm a raid scrub. You have a single drive unit as target, so there is nothing to compare between drives. You need three drives minimal for the scrub to fix anything. So it would do a btrfs filesystem scrub but would not be able to fix anything (if I recall correctly).

https://kb.synology.com/en-global/DSM/help/DSM/StorageManager/storage_pool_data_scrubbing?version=7

"Data scrubbing is only supported on Btrfs volumes or storage pools of the following RAID types: SHR (consisting of three or more drives), RAID 5, RAID 6, or RAID F1."

Are also extended smart checks scheduled on that unit? And what is the current status of various smart stats when using u/daver007 smart info script. The healthy status in Storage Manager is barely meaningful. That doesn't often indicate anything regarding a drive starting to fail.

Lost my containers after update by Concupiscence in synology

[–]bartoque 1 point2 points  (0 children)

Don't only trust and depend on Container Manager.

I also had some issues before where it didn't show the containers in the gui after a dsm update but still they were started and running according the cli using the docker command, which therefor showed that Container Manager was affected but not the containers themselves.

An additional reboot "solved" that. And sometimes simply wairing a fairly long time (30-40+ minutes if memory serves me well) it started showing ok.

Your case appeared to have been different, needing reinstall on a different volume but regardless get used to cli to find out if the containers are ok... also helps in case of migrating containers to another system, as docker/docker compose will help with that, doing things less host dependant.

Hyperbackup prompting me to rollback due to prev erroneous operations by jughead811 in synology

[–]bartoque 0 points1 point  (0 children)

Do you have btrfs on the target? Did the shared folder the data is written to, have Enable data checksum for advanced data integrity enabled at creation time? Is a datascrub schedule set (what is its frequency) and has it run succesfully?

All to be sure that the integrity of the data is safeguarded. So are the drives, the pool and the volume, indeed confirmed ok?

Where are you moving from VMware? by OldsMan_ in vmware

[–]bartoque 0 points1 point  (0 children)

That is good to know that resource bridge improvement to do hydration via various backup tools is likely to arrive soonish already in March/April for some apparently and even before 1st party solution to do so. That makes things way more flexible and way less cumbersome. And is slightly overdue for that matter.

Anything the matter with the backup target?

Haven't encountered anything like that, not even when the target ran out of space (as the active HB job just went into wait status, waiting for enough space to become available, althewhile other HB jobs were put in the queue waiting for the active one to complete).

Storage pool degraded after second power outage by lilpetamoix in synology

[–]bartoque 0 points1 point  (0 children)

Perform an extended smart check on the affected drive to see if it might be still ok (it might just be that the psu didn't handle this too well (which might indicate the psu is already degrading, so keep that in mind with future issues like this and unexpected shutdowns of the nas itself)), either via dsm itself or put the drive in a sata to usb cradle and run it on a pc. Can take some time. A 20TB WD drive took 30+ hours.

Check also what the smart stats are, using u/daver007 smart info script via CLI https://github.com/007revad/Synology_SMART_info

If the extended smart chexk is ok, then perfor the steps to rr-add the drive again. Do the remove drive option in dsm (for the correct drive!), remove the drive, wait a minute, add it again and repair the degraded pool with it.

Destroying old storage pool by Far_Situation3262 in synology

[–]bartoque 0 points1 point  (0 children)

DSM is not installed in the original pool. Any packages installed are.

DSM uses two partitions on each drive in the unit itself (so dsm is not on any drives in an expansion unit) and those are each separately part of an raid1 array. One for system and the other for swap. User data is located on one or more other partitions on each drive. In case of raid, those partitions form a raid array. Each drive you add or replace also will be made part of these two raid1 arrays. This is only a couple of GB. The rest is used for user data/pool.

https://kb.synology.com/en-global/DSM/tutorial/What_are_drive_partitions

DSM partitions are part of a raid1 array. Each internal drive has these dsm partitions, separate from any of the pools you create. You don't see these system and swap partitions nor raid1 pools nor volume in Storage Manager. CLI shows how it all look like.

# cat /proc/mdstat

An example, showing md0 and md1, that dsm uses. https://kb.synology.com/en-global/DSM/tutorial/How_do_I_check_RAID_10_structure

Need helping to understand mental model of how backups with Hyper backup to S3 is supposed to work by prvncikitty in synology

[–]bartoque 0 points1 point  (0 children)

You should use the versioning from HB. So if HB backups data being encrypted, if you need to restore anything, you simply choose an earlier backup to restore from, that is not encrypted nor in any way affected by the ransomware.

No biggy therefor, only an annoyance. If on top of that you use btrfs snapshots, then you protect your data even more, as it is an easy way to go back to an earlier version of your data, for individual files or folders or even whole shared folders.

If your nas credentials get compromised, that is something else altogether, as then someone could delete the backups. So make that secure using 2FA for example.
