March 5, 20242 yr Hi! I was preparing data on my server for setting up a backup with the features of zfs. I accessed the files on the server via my mac. First the finder froze and then the server froze. After a forced shutdown my data pool went lost. All 5 disks report as unmountable or no file system. I am not very versatile in linux or the command line. I hope there is a solution I can manage. Thanks for looking into it. server1-diagnostics-20240305-1022.zip
March 5, 20242 yr Community Expert Solution I assume it's the data zpool? Mar 5 10:16:10 SERVER1 root: cannot import 'data' as 'data': I/O error Mar 5 10:16:10 SERVER1 root: #011Recovery is possible, but will result in some data loss. Mar 5 10:16:10 SERVER1 root: #011Returning the pool to its state as of Tue Mar 5 09:14:09 2024 Mar 5 10:16:10 SERVER1 root: #011should correct the problem. Approximately 16 seconds of data Mar 5 10:16:10 SERVER1 root: #011must be discarded, irreversibly. Recovery can be attempted Mar 5 10:16:10 SERVER1 root: #011by executing 'zpool import -F data'. A scrub of the pool Mar 5 10:16:10 SERVER1 root: #011is strongly recommended after recovery. If you are OK with losing the 16 secs of data, and that's probably the only recovery option, type zpool import -F data once it's imported type zpool export data Then restart the array, pool should import normally, run a scrub.
March 5, 20242 yr Author Pool showed up in ZFS Master after import and export. Reboot was necessary to have the devices part of the pool again. One drive faulted. Scrub is in process. Might have to swap a drive. Thank you very, very much! Stress level is going down again. 😄
