[Pkg-zfsonlinux-devel] Bug#1012805: zfsutils-linux: vdev_id not working

[Gero]

Package: zfsutils-linux

Version: 2.1.4-1~bpo11+1

Severity: normal

Dear Maintainer,

I installed zfs as it's described here: 
https://openzfs.github.io/openzfs-docs/Getting%20Started/Debian/, i.e. 
installed the packages zfs-dkms zfsutils-linux from bullseye-backports

Then I tried to create disk device name mappings for a zfs pool and it 
seems that the vdev_id tool is not working or not properly configured to 
create symlinks in a new directory /dev/disk/by-vdev as promised in the 
openzfs documentation 
https://openzfs.github.io/openzfs-docs/Project%20and%20Community/FAQ.html#setting-up-the-etc-zfs-vdev-id-conf-file

At first vdev_id is not in the search path but in /lib/udev/vdev_id. 
Next, it doesn't find the config file /etc/zfs/vdev_id.conf when started 
without options. It does find it however when this very path is given 
explicitly like so:
# /lib/udev/vdev_id -c /etc/zfs/vdev_id.conf
(I don't know if that's ok or part of the problem.)

The instructions in the FAQ section of the openzfs docs state that the 
command
# udevadm trigger
should create the /dev/disk/by-vdev directory and some symlinks in it. 
This doesn't seem to work. I can't see any effect of this command, 
except for a couple of messages in /var/log/syslog:
systemd-udevd[2523]: Using default interface naming scheme 'v247'.
In particular no folder by-vdev is created.

I tried essentially with two versions of a /etc/zfs/vdev_id.conf - file:
---snip---
multipath     no
topology      sas_direct
channel 85:00.0  1         A
---snap---
and secondly:
---snip---
alias Front00   /dev/disk/by-path/pci-0000:af:00.0-sas-0x5000c500a18fb521
alias Front01   /dev/disk/by-path/pci-0000:af:00.0-sas-0x5000c500a18f2cd5
---snap---

Thanks a lot for your effort!

Regards,
Gero.
