Good to know, thanks. Maybe something in the reboot process is exporting these extra pools, causing them to be removed from the cache.
Have you guys also tried editing /etc/default/zfs and listing your extra pool(s) there? Specifically: # List of pools that SHOULD be imported at boot by the initramfs # instead of trying to import all available pools. If this is set # then ZFS_POOL_EXCEPTIONS is ignored. # Only applicable for Debian GNU/Linux {dkms,initramfs}. # This is a semi-colon separated list. #ZFS_POOL_IMPORT="pool1;pool2" There is also ZPOOL_IMPORT_ALL_VISIBLE='no' with a big disclaimer on top of it. Not saying that the current behaviour isn't a bug: just investigating options. Might need an initramfs update after changing anything in that file, tough. -- 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/1850130 Title: zpools fail to import after reboot on fresh install of eoan Status in zfs-linux package in Ubuntu: Confirmed Status in zfs-linux source package in Focal: Confirmed Bug description: Fresh installation of stock Ubuntu 19.10 Eoan with experimental root on ZFS. System has existing zpools with data. Installation is uneventful. First boot with no problems. Updates applied. No other changes from fresh installation. Reboot. External pool 'tank' imports with no errors. Reboot. External pool has failed to import on boot. In contrast bpool and rpool are ok. Manually re-import 'tank' with no issues. I can see both 'tank' and its path in /dev/disk/by-id/ in /etc/zfs/zpool.cache. Reboot. 'tank' has failed to import on boot. It is also missing from /etc/zfs/zpool.cache. Is it possible that the cache is being re- generated on reboot, and the newly imported pools are getting erased from it? I can re-import the pools again manually with no issues, but they don't persist between re-boots. Installing normally on ext4 this is not an issue and data pools import automatically on boot with no further effort.
