Message Text
LVM: Deletion of snapshot LV device [major: nnn, minor:Oxnnnnnn] failed since there are
pending I/Os on the successor LV device [major: nnn, minor:Oxnnnnnn] waiting for one
or more offline PVs to come back online.
Or,
LVM: Deletion of snapshot LV device [major: nnn, minor:Oxnnnnnn] failed since there are
pending I/Os on the predecessor LV device [major: nnn, minor:Oxnnnnnn] waiting for one
or more offline PVs to come back online.
Cause
While deleting a snapshot logical volume, if LVM detects pending I/Os due to unavailability of
underlying physical volumes on either the successor or the predecessor logical volumes, LVM will
abort the delete operation.
Recommended Action
Make sure that the disk devices being used by the entire snapshot tree (the original logical volume
and all of its snapshots) are available and healthy before retrying the delete operation.
