Hello list,
I have a two-node HA-cluster which uses local and cluster LVM.
cLVM is currently stopped, I try to remove a snapshot from the root lv which
is located on a local VG.
I get this error:
ha-idg-2:/mnt/spp # lvremove -fv vg_local/lv_snap_pre_sp4
connect() failed on local socket: No such file or directory
Internal cluster locking initialisation failed.
WARNING: Falling back to local file-based locking.
Volume Groups with the clustered attribute will be inaccessible.
Archiving volume group "vg_local" metadata (seqno 26).
Removing snapshot volume vg_local/lv_snap_pre_sp4.
Loading table for vg_local-lv_root (254:8).
device-mapper: reload ioctl on (254:8) failed: Invalid argument
Failed to refresh lv_root without snapshot.
dmesg says:
device-mapper: ioctl: can't change device type after initial table load
My LV's:

I never experienced this before and don't have any clue what's going wrong.
Help is much appreciated.
Many thanks.
