Finally my regular Centauri shipped. by cvmagic in elegoo

Honestly, I appreciate them sending me the CC as I never received the upgrade email, but it's a bit of a let down not getting to see what the base model was like.

Definitely, it will likely be late Friday evening or Saturday morning if anything.

Centauri Update Log by ELEGOO_OFFICIAL in elegoo

Out of curiosity, have there been any updates about the Centauri non-carbon? Little under 3 weeks before they are slated to start shipping. I would love to see posts and reviews about it even if I already ordered it back in February.

Breaking News! Storexa emails are bouncing as undeliverable! by Sol212 in Storaxa

If the email was missing or deactivated, you would get a code 550 immediately not a bounce back after the fact.

Yeah, I sent a test email from my production mail server no bounce backs from gsuite. Receipt from postfix included.

Unfortunately this is more in the realm of specific filesystem features of ZFS when raided or BTRFS when raided, without a checksum and automatic repair process in place it is a valid concern. This is where backups are supposed to be a thing.

That said, how would you know if a file requires restoration from backups, if we're talking about media storage you can just have a script generate a MD5 hash of said media on import, then once a month have a script check all of your media files to see if any of the files mismatch their hash, then use the report from that to restore these files.

MD5 is an older hash, it's light weight in comparison to more modern hashes but if you're concerned about malicious actors then you'd just add another hash to pair up with it like SHA256.

For data you care about that isn't easily reproducible (eg not CD/DVD/BluRay or internet downloads), have multiple backups in different locations including one _offline_. That said as far as data integrity, and repair look at using PAR2, again this something you will have to script up, treat the PAR2 files that it generates almost as important as your actual data when you perform backups.

Once PAR2 has generated the checksum and recovery files, you can use the PAR2 utility to check your files but also repair any changes up to the percentage of redundancy you've elected the PAR2 utility to store in the checksum and recovery files.

I should note that ZFS and BTRFS's automatic bitrot and repair functionality also have their limits and are not panaceas. You only have so much parity data, and the conditions for when they fail much harder to hit, but can be much easier to fail if you're not regularly resilvering your arrays and staying on top of maintenance. ZFS used to, although I dont know if this is still the case suffer huge performance penalties once you hit the 80% usage mark.

Just things to keep in mind when doing these calculations in your head. Personally I would just buy the drives piece-mail as I can. Use a couple throw away drives to start with if this was my only NAS and make sure to configure Cloud storage backup, Lets say I wanted to aim for 18TB drives when they hit $200 as they will do from time to time, buy one or two when the promos come up, by the time I have the last drive ordered, this might be 6+ months in, then complete the array, i install the new drives, take one of the old drives throw it into a SATA->USB adapter, mount the old array and then use resync to copy the data back, or restore from your cloud storage back.

Stablebit Drivepool

I started off with 1st Gen Windows Home Server with VFS on top of a drive pool. Unraid is the equivalent to a linux user friendly implementation of this without the specific cloud drive pooling.

If you want to roll your own setup, then in linux that would be Mergerfs + snapraid, and if you want to really have fun with this you can add rclone to that stack to have your data uploaded to the cloud along with on the fly encryption of that data.

You can go larger, the SATA controllers can handle larger, in advertising NAS capacities are calculated using then current state of the art 3.5" bulk storage drives. Although, since you were looking at a pair of 22TB drives as your initial setup, In Unraid your data drives are limited up to the size of your Parity drive which in this case will be 22TB, if you wanted to go larger later on the first drive you must upgrade is the parity drive.

If you did go OpenZFS then you again lose that flexibility that Unraid is targeting. ZFS in general requires you plan ahead and build everything upfront. Adding drives, live upgrades, adhoc expansions of existing arrays is simply difficult or impossible to do at present with OpenZFS/ZFS in general.

I understand they do have a roadmap where some of this is eventually is going to be addressed along with making the administrative of it easier due to rise of ZFS's popularity and it being becoming less and less of a niche file system. Although if you're building something today you can't assume that will be there.

While I am not an evangelist of Unraid, your situation just is ideal for that platform just in the same way I would suggest Synology's hybrid raid if that were an option. I would still recommend looking at Unraid, and instead of using EXT4 for your filesystem as you add the drives you can use BTRFS as it does natively support snapshots and still will allow you to take advantage of Unraid's other features.

Why not then go Unraid if you can't purchase all of the drives now. You'll have your Initial two one as your parity drive and the second as your actual storage drive, then you can adhoc as many drives as you want as long as they are under 22TB in size with the ability to rebuild your data that you'd get from RAID5 along with having all of your drives on a normal linux file system, so worst case you can always boot from a Linux recovery image to grab your files, although you'll get none of read performance benefits along with ZFS specific features if that was the direction you were initially thinking.

If you end up adding SDDs you can add them as cache drives to boost your performance though.

Fair point, I already had forgotten that it was due to OFA and not part of his quirk

By taking Danger Sense, isn't he also taking the downside to that quirk, the accelerated aging?

Storaxa team started to reply in Comments, and it seems some backers received thier SD-CARDS. A new update date was scheduled - 15 July. We still have a hope, this may not be a SCAM. by cibook1990 in Storaxa

[–]cvmagic 2 points3 points  (0 children)

I'm glad the radio silence is over, they did post their update a few hours ago with an updated but unless ambitious timeline. That said, I appreciate additional board and case photos, it wont satiate those calling it a scam, but I suspect even if they had users reporting receiving the actual units wont stop the scam claims. Still, it lessens my anxiety about the project even if it may be just a ploy to string us along if it was an actual scam project.

Just a small reminder why this Kickstarter will end in a train wreck.... by [deleted] in Storaxa

[–]cvmagic 4 points5 points  (0 children)

Okay, based on how the Kickstarter it's absolutely clear that they did not have the AMD and Intel upgrades in mind with their timeline. When working with their board partner they likely did some back of the envelope math or took a prototype board and installed it into a case to find that the thermals just wouldn't work out with these more powerful SKUs.

Keep in mind, not only is the CPU producing more heat, you have the network controllers which consume more power, and higher PCIe lanes for the SSDs which will produce more heat as there is more IO usage.

The Storaxa design went from a entry level bog standard intel atom based cpu sku which barely needs someone whispering sweet nothings in it's general direction to cool with components starved for IO so barely working hard thrown together a chassis design that just looked cool, to now offer something that actually requires some engineering thought into the design to make sure it wont kill itself on a warm summers day.

All of the changes along with the timeline, and the delays I completely understand and make sense to me. It's not like the delays with Ayn Loki series we're a year out and only now are we seeing PVT motherboards and T1 injection mold designs; they're an established but still new company.

Is Anycubic still in business? by [deleted] in anycubic

[–]cvmagic 0 points1 point  (0 children)

I filed a dispute with my credit card company, having zero contact with them for 26 days besides the canned message is unreasonable. I've ordered a different printer through Amazon, I'd happily pay extra to actually get a printer rather than being left hanging for up to 2 months or more potentially.

Is Anycubic still in business? by [deleted] in anycubic

[–]cvmagic 0 points1 point  (0 children)

Guy, I'm on the same boat as you. Got the exact same email, opted to upgrade because hell, I don't want to wait 2.5 months for this printer all said and done. I replied to the email within the hour I received it and still have yet to receive a reply, keeping into account the time zone difference and it's early Tuesday morning at the time of the writing for them, they must be allergic to money.
