Description Linus Kardell 2023-07-15 15:21:11 UTC

I am running Docker with /var/lib/docker on a zfs volume, with some directories in my docker volumes on ZFS subvolumes (so I can apply separate options for them, and take snapshots). However, after updating OpenSUSE today (previous update was on June 14), docker has started unmounting the zfs volumes. When the machine boots, they are mounted correctly, but as soon as I start docker, all but one of the subvolumes get unmounted. After rolling back the system with snapper, this does not happen.

This is probably an upstream Docker bug -- what Docker version do you have?

Comment 2 Linus Kardell 2023-07-25 20:09:17 UTC

I'm currently at 20.10.23. After the update I was at 23.0.6
