Hi,
Possible lvm2 command deadlock scenario:
crowsnest [12:15:47] /run/lvm # fuser //run/lock/lvm/*
/run/lock/lvm/P_global: 17231
/run/lock/lvm/V_lvm: 16087 17231
crowsnest [12:15:54] /run/lvm # ps axf | grep -E '16087|17231'
24437 pts/1 S+ 0:00 | \_ grep --colour=auto -E 16087|17231
16087 ? S 0:00 | | \_ /sbin/lvcreate -kn -An -s
-n fsck_cerberus /dev/lvm/backup_cerberus
17231 ? S 0:00 | \_ /sbin/lvs --noheadings

This was almost 10 hours ago.
crowsnest [12:17:44] /run/lvm # dmsetup udevcomplete 0xd4d2051
DM_COOKIE_COMPLETED=0xd4d2051
crowsnest [12:18:43] /run/lvm # ps axf | grep -E '16087|17231'
27252 pts/1 S+ 0:00 | \_ grep --colour=auto -E 16087|17231
crowsnest [12:18:45] /run/lvm #
Allows progress again.
I do not know how to troubleshoot this.
Kernel version 6.4.12 (in process of upgrading to 6.9.3).
crowsnest [12:19:47] /run/lvm # udevadm --version
254
aka systemd-utils-254.10
lvm2-2.03.22
Kind regards,
Jaco
