And another little update to previous experiment: Everything works fine with kernel 4.13.0-36 and zfs 0.7.5 IF you create new zpool with disabled unsupported features: feature@multi_vdev_crash_dump feature@large_dnode feature@sha512 feature@skein feature@edonr feature@userobj_accounting
Problem is you can't disable them on current zpool, you need to recreate zpool. And this features is enabled by default: if you do "zpool create pool /dev/disk" - they are enabled on 4.15 or you get an error on 4.13. Also disabling this features don't fix bug: if you create zpool on 4.13 kernel and after switch back to 4.15 - zfs still hangs on container restart. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1773392 Title: zfs hangs on mount/unmount To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1773392/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
