[gpfsug-discuss] Deletion of a pcache snapshot?

[Venkateswara R Puvvada]

Snapshots created by AFM (recovery, resync or peer snapshots) cannot be 
deleted by user using mmdelsnapshot command directly.  After recovery or 
resync completion they get deleted automatically. For peer snapshots 
deletion  mmpsnasp command is used.  Which version of GPFS? Try with -p 
(undocumented) option.

mmdelsnapshot device snapname -j fset -p

Firmly lining myself up for a smack round the chops with a wet haddock…
I try to delete an AFM cache fileset which I create da few days ago (it 
has an NFS home)
Mmdelfileset responds that :
Fileset  obfuscated has 1 fileset snapshot(s).
 
When I try to delete the snapshot:
Snapshot obfuscated.afm.1234 is an internal pcache recovery snapshot and 
cannot be deleted by user.
 
I find this reference, which is about as useful as a wet haddock:
