Hi,
do you mean during snapshot deletion or in general?
In general we do not have any swap usage at all. On none of the 4 hosts.
We had some swap I/O on the host that is SPM most of the time. But not
during that period where we tried to delete the snapshot.
Cheers,
Stefan

Hi,
=20
we have some really large snapshots left from a migration. Since our
store is almost full now we have to delete them now.
=20
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 no=
t
block everything?
