Ubuntu 21.10: ZFS pool automount not working (updated to 21.10 last night)

setup: Ubuntu 21.10 (with latest updates). The problem happened even before 21.10 was out. I just never bothered fixing it until now.

zfs version is:

root@myserver:~# zfs --version
zfs-2.0.2-1ubuntu5.1
zfs-kmod-2.0.2-1ubuntu5.4

I found this in the logs:

root@myserver:~# journalctl -b | grep zfs
Jan 27 09:12:21 myserver udevadm[702]: systemd-udev-settle.service is deprecated. Please fix multipathd.service, zfs-import-cache.service, zfs-load-module.service not to pull it in.
Jan 27 09:12:22 myserver systemd[1]: zfs-import-cache.service: Main process exited, code=exited, status=1/FAILURE
Jan 27 09:12:22 myserver systemd[1]: zfs-import-cache.service: Failed with result 'exit-code'.

I then tried mounting my pool using the cache

root@myserver:~# ls -al /etc/zfs/zpool.cache
-rw-r--r-- 1 root root 4016 Jan 27 08:03 /etc/zfs/zpool.cache
root@myserver:~# zpool import -c /etc/zfs/zpool.cache -aN
cannot import 'storage-myserver': one or more devices is currently unavailable

but no issues importing the pool using this command

root@myserver:~# zpool import storage-myserver

I tried recreating the cache file using the command below but auto-import still doesn't work (after a reboot) and re-running the zpool import -c command above has no effect

# zpool set cachefile=/etc/zfs/zpool.cache storage-myserver

Any ideas on how to fix? Thanks

Ubuntu 21.04 (along with all flavors) is *End-of-Life* and thus unsupported on this site (https://askubuntu.com/help/on-topic), and many other Ubuntu sites, unless your question is specific to moving to a supported release of Ubuntu. https://fridge.ubuntu.com/2022/01/21/ubuntu-21-04-hirsute-hippo-end-of-life-reached-on-january-20-2022/ https://help.ubuntu.com/community/EOLUpgrades

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
