Hello, a few weeks ago I have installed a secondary SSD for redundancy in my cache (zfs pool). My Array is in an xfs pool. all my SSDs and HDDs are pretty new (just a few months old). but sadly sometimes my Unraid keeps crashing, and all of sudden I get the following error in the console while booting up: kernel:PANIC: zfs: adding existent segment to range tree (offset=2de0a64f000 size=1000) I have googled around a bit and tried out the following ypool commands, but these arent very helpful either. unraid@tower:~# zpool status -x pool: cache state: ONLINE status: One or more devices has experienced an error resulting in data corruption. Applications may be affected. action: Restore the file in question if possible. Otherwise restore the entire pool from backup. see: https://openzfs.github.io/openzfs-docs/msg/ZFS-8000-8A config: NAME STATE READ WRITE CKSUM cache ONLINE 0 0 0 mirror-0 ONLINE 0 0 0 sdb1 ONLINE 0 0 0 nvme0n1p1 ONLINE 0 0 0 errors: 1 data errors, use '-v' for a list unraid@tower:~# zpool status -x -v pool: cache state: ONLINE status: One or more devices has experienced an error resulting in data corruption. Applications may be affected. action: Restore the file in question if possible. Otherwise restore the entire pool from backup. see: https://openzfs.github.io/openzfs-docs/msg/ZFS-8000-8A config: NAME STATE READ WRITE CKSUM cache ONLINE 0 0 0 mirror-0 ONLINE 0 0 0 sdb1 ONLINE 0 0 0 nvme0n1p1 ONLINE 0 0 0 errors: Permanent errors have been detected in the following files: <0x1207>:<0x84> also no CRC count errors in either of the SSDs is there anything I can do? tower-diagnostics-20231111-1549.zip

I think part of your observation also is that only people who have problems are looking up on this thread and posting. Those who found a solution seldom reply, but the ones who still have a problem with their config are here. For me it seems to work reliable with the 5.18 kernel, although im not a poweruser and encode only between 1 and 3 streams every evening. Plex never ever crashed tho. Hardware specs are i3 12100 (also UHD730), Asrock H610m itx MoBo and 16 gigs of 3200 DDR4 Ram.
