FYI: One can replace the "zpool import -f -a -o cachefile=none -N" line with this: local pipe="/tmp/zpool_pipe" no_import_pools=$(mkfifo ${pipe}; zpool import -f -a -o cachefile=none -N 2> ${pipe} | cut -d \' -f 2 ${pipe}; rm ${pipe})
If one wants a list of the pools which can not be imported. To just discard the error though and keep update-grub from failing this works fine too: local discard_pool_import_err="" discard_pool_import_err=$(zpool import -f -a -o cachefile=none -N 2>/dev/null || true) Maybe that workaround could be added so update-grub at least doesn't fail if a zpool which can't be imported is seen? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1848399 Title: update-grub fails if zpools with unsupported feature_flags exist To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1848399/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
