 |
|
During every shutdown, I see the following messages.
| Code: | zfs-mount |umount: /root: target is busy.
zfs-mount |cannot unmount '/root': umount failed
zfs-mount |umount: /mnt/data: target is busy.
zfs-mount |cannot unmount '/mnt/data': umount failed
zfs-mount |umount: /home: target is busy.
zfs-mount |cannot unmount '/home': umount failed
zfs-mount |umount: /: target is busy.
zfs-mount |cannot unmount '/': umount failed

How can I stop seeing those error messages during shutdown?

I don't know why localmount would be trying to unmount zfs.
Was this system originally set up on zfs, or a conversion from another install? Perhaps you have something in /etc/fstab lingering around from an old setup. |

The system was originally set up on zfs. Below is my /etc/fstab
| Code: | PARTUUID="some_uuid" none swap sw 0 0
PARTUUID="some_uuid" none swap sw 0 0
tmpfs /var/tmp/portage tmpfs size=14G,uid=portage,gid=portage,mode=775,noatime 0 0
PARTUUID="some_uuid" /boot/efi vfat defaults,noatime 0 0
tmpfs /tmp tmpfs size=8G,mode=1777,noatime 0 0

Strange, all looks good there...
I wonder if you upgraded the userland tools without updating the kernel modules (or your initrd)... a mismatch can sometimes lead to the userland tools not working correctly. |

I executed the following commands, rebooted, and shut down my computer. But, I still see the same error messages during shutdown.

@module-rebuild would only rebuild zfs-kmod and spl, and skips the userland utilities.
give this a try, create a file called /etc/portage/sets/zfs with
| Code: |
sys-fs/zfs
sys-fs/zfs-kmod
sys-kernel/spl
|
emerge @zfs, update initrd etc and reboot a couple times, if that doesn't work i'm guessing something else is at play and not zfs |

I did as you told. I'm still getting the same errors during reboot or shutdown. |
