Hello List,
I am using lvm2-2.02.180 on SLES12SP4, I cannot remove the snap LV of root
volume, which is based on multipath disk PV.
e.g.
linux-kkay:/ # lvremove /dev/system/snap_root
WARNING: Reading VG system from disk because lvmetad metadata is invalid.
Do you really want to remove active logical volume system/snap_root? [y/n]: y
device-mapper: reload ioctl on (254:3) failed: Invalid argument
Failed to refresh root without snapshot.
But, I can remove the snap LV of data volume successfully, e.g.
linux-kkay:/ # lvremove /dev/system/data_snap
WARNING: Reading VG system from disk because lvmetad metadata is invalid.
Do you really want to remove active logical volume system/data_snap? [y/n]: y
Logical volume "data_snap" successfully removed
If I use the ordinary disk as PV (rather than multipath disk), I cannot
encounter this problem (both snap LVs can be removed).
Hi
Please open new BZ case and provide full -vvvv traces of failing command
and also possibly attache 'dmsetup table' 'dmsetup ls --tree' and
'dmsetup info -c' 'dmsetup status'
Regards
Zdenek
