Drear all,we have configured scheduled creation of snapshots for several filesets in a file system.
Now, a couple of users discovered they'd been erroneously deleting files since EoJune (some script misbehaving).
The last snapshot before dates from Jun 1st and is to be deleted Aug 1st. The time for the users might be too short to check and fix their deleted data (as several might not have a chance to do so before Aug 1st).
I could not see how I could change the schedule for an existing snapshot (i.e. delay / prevent its deletion) in the GUI (invsetigating the GUI and studying the GPFS documentation / admin guide) The GUI commands include something like /usr/lpp/mmfs/gui/cli/chsnapassoc but I do not know whether that applies to existing snapshots as well or just for future ones (as the rules cover both creation and lifetime of the snaps). How I could prevent the scheduled deletion of a single snapshot (created by the GUI as scheduled snapshot)? Is that possible at all (o.k., I might stop the GUI but as there are several filesets with their scheduled snapshots, so that is not what I want actually).
