** Description changed: + == SRU Justifcation [XENIAL][ARTFUL] == + + Symlinks in /dev/zvol are not because /lib/udev/zvol_id exits with + ioctl_get_msg failed:Inappropriate ioctl for device. The core reason is + that the BLKZNAME with non-HWE userspace zfsutils is 1 char different is + size than the HWE kernel drivers. + + == Fix == + + Change the userland zvol_id tool to use the V0.6.x ZFS_MAXNAMELEN size + and if that fails with ENOTTY retry with the V0.07.0 ZFS_MAXNAMELEN size + as a fallback compatibility call. + + == Regression Potential == + + Very small, this changes zvol_id and keeps the original functionality as + well as adding V7 ZFS functionality as a fallback. At worse, zvol_id + will not work, but that's the same as the current broken state. + + == Testing == + + run /lib/udev/vol_id on /dev/zvol on Xenial with a 4.15 Xenial HWE + kernel. Without the fix one gets an ENOTTY errno failure. With the fix + zvol_id returns the zvol id and symlinks in /dev/zvol work. + + --- + Symlinks in /dev/zvol are not created because /lib/udev/zvol_id crashes with ioctl_get_msg failed:Inappropriate ioctl for device. Description: Ubuntu 16.04.4 LTS Release: 16.04 Running linux-generic-hwe-16.04-edge 4.15.0-13-generic zfsutils-linux 0.6.5.6-0ubuntu19 The version of zvol_id in zfsutils-linux_0.7.5-1ubuntu14_amd64 works without error.
