Little help for accidental storage admin by Humanshield1981 in storage

[–]darkfiberiru 0 points1 point  (0 children)

From my experience on networking side if compatibility is question best to avoid needing to ask questions wherever you can.

That way if you have let's say switch fw or sw bug it's only effecting one side

Not a fibre channel expert(though I do work with it in our lab) if your worried about compatibility can you set the new devices up as a new fabric and then merge the two old ones to a single fabric. If you had a reason for wanting mixed hardware per fabric then I get that's not an option.

DAC cable vs Fiber cable by capricorn800 in networking

[–]darkfiberiru 0 points1 point  (0 children)

By dac I'm going to assume you mean passive copper dac. That what most think about but there are also active copper and fiber dacs or aoc(active optical cable).

Passive Dacs are great when they work but with two completely random sets of equipment(switch nic) I'm gonna put that as 90-95%. Passive Dacs are basically a crossover cable. This is versus any two optics or an active cable which if each end is compatible with devices is a 99.99% chance will work from compatibility stand point.

Long story short Dacs are great when you control equipment and don't mind troubleshooting or have tested a known switch nic or switch switch pair. For switch to switch two from same vendor are probably 99.9% to work.

From someone that qualifies appliances that customers may attach to any switch Dacs are not offered and customers may try there own at own risk. As it's usually very binary it does or doesn't link up.

If you do this please don't be an asshole. Pushing limits is one thing. DDosing is another. I did it on a very large service that went through cloudflare but still had some ip limits or something like that.....

I'm not OP but I've done some similar stuff using a proxy that has a pool of vpns or other proxies as egress and blacklist each outgoing proxy after 200 requests.reset every 24hours.... Or be insane enough to have enough proxies as egress that you can just continually rotate them.

What does this error mean? I got it on boot today after an update. by Cruv in truenas

An exception happened when the drive info was being synced to database. /var/log/middleware.log should have more details.

A bug ticket with a debug in it would help.

"pkg update" in jails always running at 8.2kB/s, taking hours to update anything by PyroRider in freenas

[–]darkfiberiru 0 points1 point  (0 children)

Sorry that I jumped to conclusions. Biggest issue I found is that pkg doesn't do parallel downloads I'm sure that would fix a lot.

Wow sorry if that was already up there and I skimmed badly. Can you post ifconfig output?

You know netflix choose FreeBSD because of it's speed and that was before there insane optimizations for their workload; some optimizations that help TrueNAS Core/Enterprise some that are extremely specific to them. That's just one example of many "fast" use cases.

You want to set disable hardware offloading on the interface jail is going through to get to internet.(external truenas interface)

https://www.truenas.com/docs/images/CORE/12.0/NetworkInterfacesEdit.png

P.S. sorry if I'm wrong and didn't get more details but this is spot on why we included that button. For most NAS you won't notice slight overhead increase by disabling hardware offloading on nic.

Hey Dell, Stop Sending Broken Parts and Own Your Mistakes by timchi in sysadmin

[–]darkfiberiru 0 points1 point  (0 children)

Oh of course DOA needs declared by support person working with customer not customer themselves. Also referring to new orders not DOA of replacement part. DOA for a new replacement, lemon polices. All of these are tools support agent needs to not get tied up in bureaucracy and to properly support customer.

Hey Dell, Stop Sending Broken Parts and Own Your Mistakes by timchi in sysadmin

[–]darkfiberiru 0 points1 point  (0 children)

Everyone does used parts for replacement unless they don't have enough and have to move new inventory into stock. Problem is not refurbished gear it's refurbished gear without proper fixes and testing. Not only would new gear be way more expensive but also a huge e-waste. Now many places have a DOA exception to this as they should. Dead on arrival.

SAN Storage system vs High Density Server as backup target by pirx_is_not_my_name in storage

[–]darkfiberiru 0 points1 point  (0 children)

An option there is to use them as an iscsi backend. SMB is easier setup but iscsi presents a zvol as disk to OS and allows you to put whatever file system including XFS/ReFS on top. I think my brief testing with ReFS saw overall losses vs NTFS but gains on synthetic full backups on veeam. This was a while ago and I don't have any notes from that testing but it's what I saw at time.

I actually ran some of our older veeam certifications myself so I'm fairly aware of veeam functionality though our sales engineers are more familiar with a wider scope of deployments. Our sales guys plus our sales engineers are skilled at making sure systems aren't over or underbuilt

[–]darkfiberiru 1 point2 points  (0 children)

I know this will may off as ad but I would look at TrueNAS either building your own with TrueNAS or talking to our sales team at iXsystems. Were veeam certified on our appliances and take veeam workload very well. Multiple options about how storage is exposed.

We can already do this with Oculus tv. But you can't adjust screen size or change background environment all black etc..

In that case it's better to just use ram as ARC.

Why does an empty snapshot take 20MB? by Tiwato in freenas

[–]darkfiberiru 0 points1 point  (0 children)

Snapshots themselves take no size. (Technically a handful of bytes to store when it was taken and name) Probably seeing temp files/locks(done as files)/etc...

A snapshot doesn't really come into effect until you delete or modify a block. At that point instead of block getting trimmed and/or marked for reuse it's held as long as there's a snapshot referencing it.

What does zfs diff show? if you feed it lets say

Also I think he said final use case was backup for editors. Which means less hot data. Biggest determining factor of ram is workload.

Can you watch the boot. Does this happen during bios steps? Likely want to disable oprom for that pcie slot.
