Hi.

Data Ontap 7.3.3 on both boxes.

One of our snapvault replication is frozen (the progress size doesn't change) but I dont know how to unfreeze this situation.

Here is the "snapvault status -l" :

myfiler> snapvault status -l srcfiler:/vol/vol3/Metiers

Snapvault is ON.

The snapshot from Wed Apr 11 20:00:55 CEST 2012 is still here on the srcfiler :

Hi,

Can you simply try snapvault abort command?

I can try, but my volume is about 880 GB, and I don't want to snapvault the entire volume through a WAN connection with low bandwidth. I have to be sure that the snapshot (which is old) will be resynchronized.

I'm not sure of what the snapvault abort do, I dont want to lose snapshots of April 11th.

Tks

Does this help?

abort [-f] [ -h ] [dst_filer:]dst_path

abort -s volname snapname

Available on the primary and secondary. Cancels transfers to all dst_paths specified or, with the -s option, cancels the creation of a snapshot. The destination dst_path is on the secondary for normal updates, but is on the primary for restores. When cancelling a snapshot creation, the command also cancels all update transfers initiated as part of creating the snapshot.

Any transfer with a restart checkpoint (you can view this via the snapvault status command) may be restartable; to clear out the restart checkpoint and force any subsequent transfer to start from the beginning and possibly a different snapshot on the primary, you can use abort -h on the dst_path. The -h option specifies that this is a hard abort; the restart checkpoint will be cleared out in addition to the transfer being stopped.

The abort command can be invoked from either the primary or the secondary filer. However, the -h option is only effective on the destination filer. The option will be ignored if specified on the source filer.

The -f option forces the abort command to proceed without first asking for confirmation from the user.

Are you sure that after this abort, it will restart from the snapshot of April 11th ?

Do the "snapvault update" command works to restart the transfer ?

If you don't use -s option, then yes - it should restart the transfer from the last checkpoint.

I made a snapshot abort, then snapshot update, it seems to work, the transfer has restarted from the same Base snapshot.

Tks a lot.
