Delete snapshots - handle snapshot lookup and make it concurrent

Question

Opened this issue 5 years ago · 2 comments

Deleting a large number of snapshots sequentially is very slow. We can optimize it by working storagedriver based and launch multiple concurrent tasks this way
vdisk.snapshot_ids can throw errors if the volumedriver does not respond. This path is currently not caught and causes the whole task to bail out

Will be implemented by #2298

Framework concurrency added by #2298.
This implementation still iterates on the snapshots, causing a snapshot.xml update each time.

The volumedriver implemented a delete_snapshots call which can be used instead: https://github.com/openvstorage/volumedriver-ee/issues/207
