Snapshot overflow error. Partial transfer due to error

You can increase any of the Logical Volumes including the Snapshot, just go where you created the NAS or iSCSI Logical Volume and select "Modify" for that Logical Volume. We do not have a way to shrink a Logical Volume. Link below has allot of details on how our snapshot works.

2010.12 How to work with Snapshots and how to replicate your data

[joolsc]

Thanks for the information, very useful. I now realize that unless we have a large snapshot size that is definitely bigger than any changes to the main volume corruption can occur as snapshot space is exhausted.

So make sure snapshot volumes are big enough!

In fact what we're doing now is when we want to copy a large amount of data over we just turn off the snapshot task make sure current running task is all finished then do the copying, turn task back on when copying completed.

It then seems that the data replication can catch up with all the changes made since the task was stopped?

Have I got this right?

Yes this will work or just like you said know what is the amount of changes you will by 3X though this can be tough to know as well, so I just go with 12-15% of the size of the Snapshot to the NAS volume.
