#raid10 — Public Fediverse posts

question for tech-y storage people: I just nabbed 4 extra (used) disks with a 6 TB capacity from a place that re-sells electronics (oregonrecycles.com); I think they did some testing but obviously I dunno what to extent, and also, if it was just limited to stuff like SMART data, well...

anyway, I wanna RAID it, which is fine, but I don't know how much lifetime these have left on them. For four disks with unknown usage, should I use RAID6 or RAID10? It's not job critical data I'll be storing on these (mostly media and such). They'll eventually be migrated into a larger RAID array but that won't happen until I'm stable and can afford to rebuild my server so this is fine for now.

I wouldn't mind the better read/write performance that comes with RAID10 even though it has less parity. I suspect these disks were all used together so they might have similar wear/tear patterns; in that case, I'm wondering if RAID6's double parity actually buys me any extra life? Like, given 4 disks with the same history and a probably known disk failure rate, I'm not really clear as to whether double parity is going to make much of a difference (and that if one goes down, the others probably aren't too far behind).

Can anyone confirm whether with #softraid #raid10 you can safely remove a faulty drive from an array even if it contains the root partition of the live system? I found mixed information on this. #linux

My #NFS might have commit death, but I'm not sure how yet... So far from the autopsy: Two physical disks in a #RAID10 virtual disk have failed. It seems they may be the same stripe but I'm unsure how to confirm. I've ordered two new disks to try and rebuild the raid but I think any of the non-archived data will be lost 😭 if I have to restore data from my archives, I may push mastodon to use a smaller disk for media instead of NFS.

Any #Dell #PowerEdge #Debian or relevant perspective welcome!!

Just out of pure curiousity, but does anyone in their #HomeLab have a #StorageAreaNetwork or #SAN for short? I am contemplating setting one up with a few #SBCs or low wattage machines, with all #RAID1 set-up instead of #RAID10 on a single machine.

What are you thoughts about that scenario community? #100DaysOfHomeLab #SelfHosted #SelfHosting
