I've also gotten bitten by this. Upgrading to Ubuntu 21.10 caused weird filesystem issues to be present on my ZFS filesystem, with errors on the command-line such as:
Cannot access 'foobar': No such file or directory When running ls -l in some directory, I get question marks, like this: -????????? ? ? ? ? ? enum_binary_params.hpp -????????? ? ? ? ? ? enum.hpp I tried to select the "revert" option in the Grub boot menu to go back to Ubuntu 21.04, and that worked. I then tried to install a fresh installation of Ubuntu 21.10 from a USB stick, selecting the ZFS option with encryption, and I am getting these errors again. I only noticed now this note in the release notes: > The version of the ZFS driver included in the 5.13.0-19 kernel contains a bug 16 that can result in filesystem corruption. Users of ZFS are advised to wait until the first Stable Release Update of the kernel in 21.10 before upgrading. I know that this comment is not that useful to Ubuntu developers, but I'm posting it for the benefit of those searching for this issue in their favourite search engine. ** Also affects: ubuntu-release-upgrader (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1906476 Title: PANIC at zfs_znode.c:335:zfs_znode_sa_init() // VERIFY(0 == sa_handle_get_from_db(zfsvfs->z_os, db, zp, SA_HDL_SHARED, &zp->z_sa_hdl)) failed To manage notifications about this bug go to: https://bugs.launchpad.net/zfs/+bug/1906476/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
