[SOLVED] ZFS Pool Import on boot

[skinnyl]

Hi there,

I'm getting the following error on boot..
[FAILED] Failed to start zfs-import..rvice - Import ZFS pool zfs01
But after a while it boots and mounts all the pools

This is what I've noticed in syslog..

Now, I've read a few similar threads, but I'm not 100% on what to do here, I tried the below with no change.

zpool set cachefile=/etc/zfs/zpool.cache YOUR_POOLNAME
update-initramfs -k all -u
reboot

I'm pretty sure this happened after installing a new network card, all the pool drives are nvmes on a pci controller.

Help apprecaited.

Thanks, Jack.

Also tried the below posts advice.

Which has removed the 'FAILED' error but left me with a long boot time and the below which doesn seem 100% happy..

Again, if left, it comes up fine but would like to smooth it out if possible.

Thanks.

Edit:

Would: /lib/systemd/system/zfs-import-cache.service need 'zpool.cache' changed to 'zpool2.cache' after doing this:

// Edit:
Just for all those who find this thread, I just re-disabled the import for my datapool with systemctl disable zfs-import@zfs01 and changed the cachefile of this pool to a seperate one /etc/zfs/zpool2.cache with zpool set cachefile=/etc/zfs/zpool2.cache zfs01.

Had time this morning to test the above, and renaming to 'zpool2.cache' seems to have done the trick - no errors in the syslog or on boot. Boot was faster too. Marking as solved for future pilgrims.
