Hi! I swapped my Epyc CPU with an inferior one, so I could move the better one to an app server.
While I was screwing in the new processor, the NAS turned on. I quickly turned it off, but now when I turn it on, even after a restart, it’s saying the two data zpools are gone. The only pools showing up are the boot-pool and TrueNAS apps pool:
My processor is showing up correctly:
My drives are all here and correctly showing which pool they belong:
Actually, that’s not true. There should be two more NVMe drives. I’m gonna look into that. Either way, those are for the Bunnies pool, not the Wolves pool. I’m wondering why these two pools suddenly went offline and won’t come back online.
Side note: I did remove two 2TB drives from the NAS as well. I’m gonna re-add those. I wonder if they were somehow in use for the Wolves pool. I was pretty sure that section of the NAS had drives that weren’t in use, but it’s possible I messed up and just happened to remove the two drives that were part of Wolves.
Does TrueNAS just OFFLINE zpools if something’s missing?
Looking at my drive chart, it appears as though two drives in this section are part of the Wolves pool:
Not sure those are the ones I removed, but I’ll move them back if that’s the case. Even if I fix this issue tonight, I wanna leave this topic here in case anyone else notices the same thing.
I readded those Wolves 2TB drives and made sure all the NVMe SAS-style connectors are snug in the drives. Those connectors are very prone to coming out because you looked at them wrong.
After restarting TrueNAS, Wolves is fixed, but Bunnies still has issues:
I’ll see if I can reseat those NVMe cables one more time.
Once I get them showing up, are you saying I don’t have to restart, there’s a way to online the pool? After plugging in those drives for Wolves, it didn’t online the pool until I restarted TrueNAS.
For Bunnies, Changing out the CPU changes my NVMe settings for my SlimSAS ports, so that made two NVMe drives become unavailable (loading in SATA mode).
For Wolves, I had taken out the wrong 2TB drives. The ones I pulled were used for metadata.
If I can make a suggestion, for future hardware maintenance operations, please unplug your system entirely from the power source before changing non-hot-swap components like memory or processors. Especially in systems that have a BMC (baseboard management controller) there can still be energized components, or it may be reading information to inventory them.
