Software incompatibility detected between Commvault Intellisnap backup software and lvm2-lvmetad.service/socket.

This document (000020734) is provided subject to the disclaimer at the end of this document.


SUSE Linux Enterprise Server 12 SP5
SUSE Linux Enterprise Server for SAP Applications 12 SP5
SUSE Linux Enterprise Desktop 12 SP5


The issue is detected with SLES12 SP5, but it can also be observed with other SLES/SLED versions or configurations using lvmetad and running the 3rd party Commvault Intellisnap solution.

First, check if the system is using lvmetad for lvm metadata caching, like so:
hostname:~ # grep "use_lvmetad =" /etc/lvm/lvm.conf
        use_lvmetad = 1
If the boolean is true, then the system is using lvmetad.
hostname:~ # systemctl status lvm2-lvmetad.service
â lvm2-lvmetad.service
   Loaded: masked (/dev/null; masked)
   Active: inactive (dead) since Fri 2022-08-19 20:56:52 CEST; 2 days ago
Main PID: 1682 (code=exited, status=0/SUCCESS)
Aug 19 18:03:11 hostname systemd[1]: Started LVM2 metadata daemon.
Aug 19 20:56:52 hostname systemd[1]: Stopping LVM2 metadata daemon...
Aug 19 20:56:52 hostname systemd[1]: Stopped LVM2 metadata daemon.
Aug 19 20:56:52 hostname systemd[1]: Stopped LVM2 metadata daemon.

When using the Intellisnap software, on checking the status of the lvm2-lvmetad.service:

systemctl status lvm2-lvmetad.socket

...the result will appear as masked.

This may lead to the system entering initramfs (maintenance mode) on next reboot, depending on your lvm configuration.


You might have to manually re-enable the lvmetad:
# systemctl enable lvm2-lvmetad.service
# systemctl enable lvm2-lvmetad.socket
If the system is in maintenance mode upon reboot, please start the following services:
# systemctl start lvm2-lvmetad.service
# systemctl start lvm2-lvmetad.socket


The Commvault backup software masks the lvmetad service and socket, which when combined with a configuration that depends on lvmetad can lead to an inability to find appropriate devices necessary for boot
