[ovirt-users] Deleting large snapshots blocks the whole cluster

Do you see swapping on the SPM? If yes a regular echo 3 > drop_caches could help.

Hi,

we have some really large snapshots left from a migration. Since our
store is almost full now we have to delete them now.

Some snapshots are around 1TB already.

The last time we tried to delete a ~500GB snapshot the delete task
blocked the whole diskstore's IO and the whole cluster and all hosts
became unavailable.

Is there a way to delete large snapshots in a "humane" way that will not
block everything?

Cheers,
Stefan
