description |
[Impact]
The issue arises from the installation of the udev rules file /lib/udev/rules.d/68-del-part-nodes.rules by kpartx.
This file references /usr/sbin/partx, but on Debian, partx is located in /usr/bin.
This incorrect path leads to the following error:
systemd-udevd[3302364]: sdrg: Process '/usr/sbin/partx -d --nr 1-1024 /dev/sdrg' failed with exit code 1.
[Fix]
The upstream has a patched fix available.
https://salsa.debian.org/linux-blocks-team/multipath-tools/-/blob/master/debian/patches/0003-kpartx-rules-use-Debian-specific-partx-path.patch?ref_type=heads
[Test Plan]
1. Verify the udev file located at /lib/udev/rules.d/68-del-part-nodes.rules.
2. Ensure that the path for partx matches the output of the "which partx" command.
[Where problems could occur]
The patch specifically targets a single udev rule responsible for deleting partition devnodes for slave devices associated with specific aggregate devices, like multipath. This modification solely adjusts the path of the partx command. If the path is incorrect, the devnode will persist. |

[Test Plan]
1. Prepare a VM with two NICs and setup an iSCSI target
root@focal:~# cat /etc/tgt/conf.d/iscsi.conf
<target iqn.2024-05.storage.com:disk1>
backing-store /dev/sdX
</target>
2. Prepare another VM and execute iSCSI discovery and login
iscsiadm -m discovery -t sendtargets -p XXX
iscsiadm -m node --login
3. Show multipath topology
multipath -ll
4. Use the following command to trigger the udev rule
udevadm trigger --subsystem-match="block" --name-match=sdX
5. Confirm that there is no following error in /var/log/syslog
systemd-udevd[1788]: sdX: Process '/usr/sssbin/partx -d --nr 1-1024 /dev/sdX' failed with exit code 1.
