There's more trouble. I just copied several TB of data by zfs send | zfs recv from a 20.04 machine to this new machine. Worked well for hours, but at the end some crash messages, see attached second dmesg.
ZFS as it comes with 21.10 is definitely not production ready. ** Attachment added: "dmesg output of kernel problems" https://bugs.launchpad.net/ubuntu/+source/zfs-linux/+bug/1947498/+attachment/5534455/+files/dmesg2 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to zfs-linux in Ubuntu. https://bugs.launchpad.net/bugs/1947498 Title: zfs/zpool encryption crash on server 21.10 Status in zfs-linux package in Ubuntu: New Bug description: Hi, just installed a new HPE microserver with SSD and four harddisks with new 21.10 server and tried to create a zpool with zpool create pool1 raidz2 /dev/sda /dev/sdb /dev/sdc /dev/sdd -O encryption=on -O keyformat=passphrase which reproducably crashed twice with the attached kernel message. The zpool then exists, but is not encrypted. zpool create pool1 raidz2 /dev/sda /dev/sdb /dev/sdc /dev/sdd without the option works and a subsequent zfs create pool1/sub -o encryption=on -o keyformat=passphrase works as well. Which is, however, not a real workaround for a fully encrypted pool (which worked under 20.04). regards ProblemType: Bug DistroRelease: Ubuntu 21.10 Package: zfsutils-linux 2.0.6-1ubuntu2 ProcVersionSignature: Ubuntu 5.13.0-19.19-generic 5.13.14 Uname: Linux 5.13.0-19-generic x86_64 NonfreeKernelModules: zfs zunicode zavl icp zcommon znvpair ApportVersion: 2.20.11-0ubuntu70 Architecture: amd64 CasperMD5CheckResult: pass Date: Sun Oct 17 12:44:15 2021 InstallationDate: Installed on 2021-10-17 (0 days ago) InstallationMedia: Ubuntu-Server 21.10 "Impish Indri" - Release amd64 (20211013) SourcePackage: zfs-linux UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/zfs-linux/+bug/1947498/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
