Package: lvm2 Version: 2.03.31-2 Severity: important X-Debbugs-Cc: [email protected]
On trixie and sid systems, attempting to remove a shared VG hangs
forever. The process must be terminated via `kill -9`.
Originally observed in a clustered Incus environment, the problem is
trivial to reproduce on a minimal trixie install:
gibmat@debian:~$ dpkg -l | grep lvm
ii liblvm2cmd2.03:amd64 2.03.31-2
amd64 LVM2 command library
ii lvm2 2.03.31-2
amd64 Linux Logical Volume Manager
ii lvm2-lockd 2.03.31-2
amd64 LVM locking daemon
gibmat@debian:~$ sudo vgcreate --shared vg /dev/vdb
Enabling sanlock global lock
Logical volume "lvmlock" created.
Volume group "vg" successfully created
VG vg starting sanlock lockspace
Starting locking. Waiting until locks are ready...
gibmat@debian:~$ sudo vgs
VG #PV #LV #SN Attr VSize VFree
vg 1 0 0 wz--ns <20.00g <19.75g
gibmat@debian:~$ sudo vgremove vg
^C^C^CKilled
Force-downgrading to lvm2 packages from bookworm works as expected:
gibmat@debian:~$ dpkg -l | grep lvm
ii liblvm2cmd2.03:amd64 2.03.16-2
amd64 LVM2 command library
ii lvm2 2.03.16-2
amd64 Linux Logical Volume Manager
ii lvm2-lockd 2.03.16-2
amd64 LVM locking daemon
gibmat@debian:~$ sudo vgcreate --shared vg /dev/vdb
Enabling sanlock global lock
Physical volume "/dev/vdb" successfully created.
Logical volume "lvmlock" created.
Volume group "vg" successfully created
VG vg starting sanlock lockspace
Starting locking. Waiting until locks are ready...
gibmat@debian:~$ sudo vgs
VG #PV #LV #SN Attr VSize VFree
vg 1 0 0 wz--ns <20.00g <19.75g
gibmat@debian:~$ sudo vgremove vg
Volume group "vg" successfully removed
Apparently this works fine on current Fedora systems, which implies
this problem was fixed by the time of the 2.03.38 release of lvm2.
