Re: [gpfsug-discuss] Bit of a rant about snapshot command syntax changes
The old syntax works unless have a colon in your snapshot names. In that case,
the portion before the first colon will be interpreted as a fileset name. So
if you use RFC 3339/ISO 8601 date/times, that’s a problem:
The syntax for creating and deleting snapshots goes from this:
mm{cr|del}snapshot fs100 SNAP@2016-07-31T13:00:07Z –j 1000466
to this:
mm{cr|del}snapshot fs100 1000466:SNAP@2016-07-31T13:00:07Z
If you are dealing with filesystem level snapshots then you just need a leading
colon:
mm{cr|del}snapshot fs100 :SNAP@2016-07-31T13:00:07Z

I think at least the most popular old forms still work, even if the
documentation and usage messages were scrubbed.
So generally, for example, neither your scripts nor your fingers will break. ;-)

Why was mmdelsnapshot (and possibly other snapshot related commands) changed
from:
Mmdelsnapshot device snapshotname –j filesetname
TO
Mmdelsnapshot device filesetname:snapshotname
..between 4.2.0 and 4.2.1?
It’s mildly irritating to say the least!

Re: [gpfsug-discuss] Bit of a rant about snapshot command syntax changes
Thanks Marc. Regrettably in this case, the only way I knew to delete a snapshot (listed below) has broken going from 3.5 to 4.2.1. Creating snaps has suffered the same fate.
