~~I guess you need to "zpool import -f" because your system has crashed before and did not shutdown properly.~~
After reading again, I understand that your pool is alive and well. It is just not mounted anywhere.
Look into /etc/fstab if you find the correct mountpoint there. Then tell it to your ZFS with "zfs set mountpoint= "
The trick for this one is mount -t zfs -o zfsutil internal /mnt/some/path
Assuming the root dataset is mountable. If you have a -o canmount=off on the dataset it will refuse to mount.
If it's -o mountpoint=legacy then you don't need -o zfsutil, but still need to provide both the source and destination paths. Otherwise you'll get the fstab error because mount can't figure out what to mount or where to mount it.
Thank you so much, where did you find this bit of information? I have been trying to solve this problem for the past week or so, but my google foo failed me on this one. Was about to give up on this one.
I learned it accidentally trying to get root on an encrypted dataset working with systemd init without sd-zfs. This turns out to be how the zfs utility works internally to signal the driver "hey it's okay, I'm a ZFS utility the user isn't using mount directly", and how you deal with mounting your root dataset to the temporary /sysroot while having its mountpoint set to / while in initramfs before pivoting root.
Obviously, don't use that other than recovering your data, if you want to use this array you should figure out the mountpoints properly so ZFS does it automatically. It shouldn't break anything but it's gross, either set mointpoint=legacy and use fstab or set its mountpoint in ZFS and use zfs mount.
Maybe @[email protected] can help. I'm not in my pool right now.
For anyone with ZFS related issues I'd honestly recommend just going to Jim's site- https://discourse.practicalzfs.com/ which is invaluable. Lot more help and a trove of valuable info already exist there.
Thank you will have to look into that particular forum. Though my problem has been solved for now I will definitely have more things that come up in the future and that seems like just the place for this sort of thing.
It states it can't find it in /etc/fstab. So do you have it there? And does it have the correct ID?
(I don't know how zfs pools work, I'm just going of what the mount command said)
