July 29, 20232 yr Hi all, apparently its my luck that this happens a day before I go travelling. I have 2 new 16TB Western Digital "My Book" that I have connected to my unraid. I decided about a week ago to format them both with ZFS (To try out ZFS), so I did and filled them with data. Today, I shut down both servers and moved the disks to the second server, so I could back them up. Upon starting up, the first disk will not mount, but the second appears to mount fine, both were formatted the same way without errors. Checking the disk log I see this: text error warn system array login Jul 29 23:13:14 soundwave kernel: sd 1:0:0:0: [sda] Very big device. Trying to use READ CAPACITY(16).

I can't see any other obvious errors, I tried detatching and disconnecting both disks, then reconnecting and same scenario (disk 1 fails to mount). This is the fist time I'm using ZFS, and I'm not sure where to start. I can't find any other details in the Ui, there are no SMART errors showing, its a new disk a week old. Can anyone help?

July 29, 20232 yr Author Some responses I've seen so far: # zpool import /dev/sda cannot import '/dev/sda': no such pool available # zpool import no pools available to import # zfs mount sys_sync2 /mnt/disks/sys_sync2 # zfs list NAME USED AVAIL REFER MOUNTPOINT sys_sync 14.4T 128M 14.4T /mnt/disks/sys_sync1 sys_sync2 12.5T 1.95T 12.5T /mnt/disks/sys_sync2 I also tried: # zfs mount sys_sync but this appears to hang and do nothing.

July 31, 20232 yr Community Expert If "zpool import" doesn't show anything the pool was likely damaged and it can no longer be imported.
November 15, 20232 yr U V: 6:12.4 - all plugins up to date. I am also getting this error on a (x6) disk z2 pool in UD. I created the pool in the array with the gui. Then moved the disks to UD, as it's going to be an offsite backup, then deleted the pool from the unraid gui. Mounted the pool in UD and moved the backup images over. Everything transferred without issue. I unmounted it went about my day till i remembered i wanted to put one more folder in the backup pool before i move it to its new home across town...now it wont mount.

Nov 15 11:16:39 miiCARstorage unassigned.devices: Mount of 'sdae1' failed: 'Cannot determine Pool Name of '/dev/sdae1'' it doesn't matter which of the 6 disks i click mount on, it says the same info (just changed to match the disk i am clicking mount on)
November 15, 20232 yr Community Expert UD doesn't support zfs pools, you can import the pool manually with zpool import.

Anyway...i think i am having USB issues, as random issues come and go lately.

November 20, 20232 yr Community Expert Good to know, was under the impression that multi disk zfs pools were not supported by UD.
