[Bug 1688890] Re: initramfs-zfs should support misc /dev dirs
I haven't had a chance to write and test the zpool.cache copying. I keep meaning to get to it every day, but pushing it back for lack of time. The zfs-initramfs script in 16.04 (always) and in 18.04 (by default) runs a plain `zpool import`. ZoL 0.7.5 has a default search order for imports that prefers /dev/disk/by-id: https://github.com/zfsonlinux/zfs/blob/zfs-0.7.5/lib/libzfs/libzfs_import.c#L1835 That said, so did ZoL on Xenial (0.6.5.6). On my bionic test VM, non-root pools import using whatever name I created them with. If I use /dev, they import later with /dev. If I use /dev/disk/by-id, they import later with /dev/disk/by-id. This is true immediately, and true across reboots. Root pools seem to behave the same way. My root pool was created using /dev/disk/by-id per the HOWTO (which I maintain) and is being imported with /dev/disk/by-id. This is with no zpool.cache, either on the live system or in the initramfs (which I unpacked to verify). In other words, I cannot reproduce this on bionic. I'm pretty confident this is an issue on Xenial, though I haven't re-tested just now to absolutely confirm. But I will say that on my Xenial laptop at the moment, my root pool is imported with a /dev name. In short, I think this is fixed in Bionic, but I'm not 100% sure which code changed to fix it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1688890 Title: initramfs-zfs should support misc /dev dirs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/zfs-linux/+bug/1688890/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1688890] Re: initramfs-zfs should support misc /dev dirs
I need to do some testing, but we might want to consider using the cache file. An approach (suggested to my by ryao, I think) was that we first import the root pool read-only, copy the cache file out of it, export the pool, and then import the pool read-write using the cache file. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1688890 Title: initramfs-zfs should support misc /dev dirs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/zfs-linux/+bug/1688890/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
