Dull IT moment

I reviewed my NAS today and determined that I'm running on borrowed time.

Do you have it in a drive failure tolerant RAID configuration?

CMDR_Horn@lemmy.world · 14 pts · 357d (6 replies)

2x6 vdev raidz2. All of the ones with failures are in vdev2 so I just ordered 6x 22tb replacements to not only get rid of the bad drives, but also expand the pool

Wait, you can expand raidz pools?

CMDR_Horn@lemmy.world · 14 pts · 357d (4 replies)

Yes, but only if you replace all the drives in a vdev with larger capacity drives. After the resilvering the pool will grow to the new capacity

9tr6gyp3@lemmy.world · 13 pts · 357d (3 replies)

So if you slowly replace the drives with bigger capacities (say 1 replacement a month), you won't actually gain the extra capacity until you've gone through and replaced all the drives (which if you did 1 a month, 6 drives would take 6 months)?

Correct. So long as the resilvering finishes you're golden.

And you're on a newer updated version of zfs

Cool, thanks for clearing that up. Im building a home server atm and working through which file system to go with. I have 4x enterprise SSDs that im going to start with, and some of it will be used for NAS storage, among other services.

I know zfs has a lot of fans, but im personally more experienced with btrfs, so trying to decide between the two.

CMDR_Horn@lemmy.world · 7 pts · 357d

I've never done raid with btrfs. I've only used it for OS disks, so I couldn't really say it'd be a good option. I do trust zfs though.

At least they aren't all the same age, so the chances of multiple failures at the same time is reduced!

CMDR_Horn@lemmy.world · 12 pts · 357d (3 replies)

True, but resilvering all those drives scares ms.

What does silvering mean?

CMDR_Horn@lemmy.world · 9 pts · 357d (1 reply)

Basically moving blocks to rebalance/redundant a pool

Zfs term for rebuilding a raid array
