VNX: Unable to create checkpoint of a file system (Replication Destination)

Checkpoint creation is unavailable.

Example:

[nasadmin@VNX ~]$ fs_ckpt FS1 -C
operation in progress (not interruptible)...

Unisphere Creation might show a creation task running (and is unavailable) for ever.

File system is a replication target (Read-Only File system with Replication Internal Checkpoints exist)

Replication destination file systems have 2 internal (root) checkpoints.

During replication data transfer (whether manually refreshed or automatically pushed with new incremental data), Replicator service locks the SavVol and it releases the SavVol once the transfer is completed.

Some time, this may is unavailable for the following reasons:

1. SavVol hit maximum space and unable to auto extend the savvol
2. Interconnect is paused or some network issue between source and destination, which causes the replicator unable to finish the transfer and release the savvol
3. Disk failed and resulting in file system corruption/unmount

Until the above conditions are resolved, no checkpoint activities like create, delete is possible for all kinds of checkpoints.

Fix the issues explained in the Cause Section.

If still unable resolve, quote this KB to EMC Support for advanced methods which might require (be prepared):

• Data Mover (destination only) Reboot
• Replication might require deletion, and new full replication may be required to re-create
