Importing ZFS pool takes forever on boot
Clash Royale CLAN TAG#URR8PPP
I recently moved my Gentoo (OpenRC) root to ZFS, and so far everything works great, except for one thing: importing zpool takes a long time (one-two minutes) on boot.
After the import is finished it says:
Import of gentoo succeeded...
[other unimportant stuff]
/newroot is a mountpoint
chroot: can't execute '/usr/bin/test': No such file or directory
Also, zpool status shows "sda" instead of disk/by-id entry. I can't figure out how to make it use /dev/disk/by-id instead, since this is rootfs and I can't re-import it while the system is running. Re-importing the pool from a LiveUSB doesn't change anything.
Here's how my zpool status looks:
pool: gentoo
state: ONLINE
scan: none requested
config:
NAME STATE READ WRITE CKSUM
gentoo ONLINE 0 0 0
sda ONLINE 0 0 0
errors: No known data errors
linux filesystems gentoo zfs openrc

Importing can be slow if it has to read metadata for many filesystems, since import has to scan all the filesystems to decide which ones to mount / where to mount them. Do you have lots (i.e. thousands) of filesystems / zvols on the pool? I don't think snapshots contribute to that, but I suppose it's possible.
