Hey all! I’ve just been a lurker for a while but now I’ve finally got something to post about:
I recently got an Orico USB 3.5" enclosure set up as a raidz1 array with 4 fresh (or as fresh as fac refurb gets) 22tb Exos disks which has been a nice little bump in capacity over my tiny nvme box. However, a few days ago I ran into a minor issue where attempting to access it would cause any process to hang into (seemingly) infinity, since the ZFS array had been suspended due to IO errors. At the time I just made the very half-arsed assumption that I needed to remount the zpool with UUIDs thinking drive labels got mixed up or something.
Come to find out an hour or so ago, that definitely wasn’t the problem. I learned this the hard way after spending longer than I’d like to admit debugging my wip Nexcloud stack thinking I was just really screwing up my dockerfile for having to go in and kill the dysfunctional container processes manually.
I saw a random thread somewhere about how a certain kernel update caused what seemed to be the same issue for someone’s USB drive, but that was all I really found. I would just try downgrading kernels, but I’m not home at the moment and the last time it happened there were a bunch of aforementioned stalled processes that prevented system shutdown, so not particularly keen on messing with that remotely until I know more.
In essence: Are there any known related issues with the below versions and/or potential workarounds?
I’m currently running Ubuntu 24.04.2 LTS with kernel version 6.8.0-55-generic
zfs version:
zfs-2.2.2-0ubuntu9.1 zfs-kmod-2.2.2-0ubuntu9.1
Model of drive enclosure:
pool: zenpool
state: SUSPENDED
status: One or more devices are faulted in response to IO failures.
action: Make sure the affected devices are connected, then run 'zpool clear'.
