Message Text
vmunix: LVM:ERROR: The task to increase the pre-allocated extents could not be posted
for this snapshot LV (VG 128 0x000000, LVM Number 3).
Please check if lvmpud is running.
Cause
If the automatic increase of pre-allocated extents is enabled for a space efficient snapshot, the
numbers of pre-allocated extents are automatically increased when the threshold value is reached.
The lvmpud daemon must be running for this to succeed. When lvmpud is not running, the above
message is logged.
Recommended Action
Start the lvmpud daemon. Refer to the “Managing the lvmpud Daemon” (page 107) section.
Message Text
vmunix: LVM: ERROR: The task posted for increasing the pre-allocated extents failed
for the snapshot LV (VG 128 0x004000, LV Number: 48).
Cause
The above message is logged when LVM fails to increase the pre-allocated extents automatically.
This message should not be seen frequently. If seen frequently, it must be a LVM software or
configuration issue.
Recommended Action
Increase the number of pre-allocated extents for the space-efficient snapshot using the lvextend
command to prevent the snapshot from becoming inoperative.

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. Please make the PVs available and retry.
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. Please make the PVs available and retry.
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.
