Not able to lock volume. Event ID 144 (Pagefile)
Issue:
DataKeeper was not able to lock a volume and received the following error:
Log Name: System
Source: ExtMirr
Date: 4/26/2013 10:10:18 AM
Event ID: 144
Task Category: Mirror Creation
Level: Warning
Keywords: Classic
User: N/A
Computer: 12345
Description:
The volume could not be locked as requested.
Volume Device:
Local Volume : V
Error Code : 0xC0000022
There was an error locking the volume. (The error code above is a driver status value).
RECOMMENDATION/SOLUTION:
Disk locks will fail if a pagefile exists on the target of the mirror. It will not allow the mirror to be continued from a paused/broken state if the target is accessible (unlocked). When this occurs a tool like “process explorer” will show one or more open handles to a pagefile on that volume.
Ensure there is no pagefile on the offending volume (in this case it was the target DK volume).
A system administrator had accidentally placed this pagefile on a mirrored volume after the mirror had been created.
DataKeeper does not support mirroring to or from volumes containing Windows pagefiles.
Volume goes into a RAW state when the emcmd . unlockvolume command is run
Issue:
- Able to create a mirror
- Once created and the emcmd . unlockvolume command is executed the Targeted volume enters into a RAW state per Disk Management
Solution:
Verify that the Bytes Per Physical Sector are identical on both the Source and Targeted volumes.
