  * Fix volume wait on locked encrypted zvols (LP: #1888405)

      zfs-volume-wait.service systemd unit does not start if the encrypted
      zvol is locked. The /sbin/zvol_wait should not wait for links when the
      volume has property keystatus=unavailable. Add a check for this.

Hello James, or anyone else affected,

Accepted zfs-linux into focal-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/zfs-linux/0.8.3-1ubuntu12.3 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed-focal to verification-done-focal. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-focal. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping!

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

Tested with an encrypted locked zfs volumne, verified and no regressions found.

Here is a completely untested patch that takes a different approach to the same issue. If this works, it seems more suitable for upstreaming, as the existing list_zvols seems to be the place where properties are checked. Can either of you test this? If this looks good, I'll submit it upstream.

I've posted this upstream (as a draft PR, pending testing) at: https://github.com/openzfs/zfs/pull/10662
