Comment 57 for bug 1906476

I installed Ubuntu 21.10 system with ZFS and encryption, and I installed all APT updates. I quickly started experiencing filesystem corruption within an hour or two, and now my system won't boot. I see that this bug has been marked "Fix Released", but I am still experiencing it.

Even before the bug fix is released, I urge the developers to take urgent preventative measures to stop users from experiencing filesystem corruption, especially users who are upgrading, since they have more data to lose. Specifically, I ask you to take these three actions:

1. Make the upgrade tool refuse to upgrade to Ubuntu 21.10 if ZFS is being used, until a permanent fix is released.

2. If possible, don't allow users to install a fresh installation of Ubuntu 21.10 with ZFS enabled. I don't know if it's possible to release a new ISO, but please consider that it might be worth releasing a 21.10.01 ISO.

3. The release notes for Ubuntu 21.10 do contain warnings about filesystem corruption when using ZFS, but you have to read 2800 words before reaching the paragraph that warns about this. Please consider modify the release notes to make this warning more prominent. Also, modify any other web pages that users might check before installing Ubuntu 21.10 or upgrading to it.
