[gpfsug-discuss] DMAPI - Unmigrate file to Regular state

[Miroslav Bauer]

Hello,

is there any way to recall a migrated file back to a regular state
(other than renaming a file)? I would like to free some space
on an external pool (TSM), that is being used by migrated files.
And it would be desirable to prevent repeated backups of an
already backed-up data  (due to changed ctime/inode).

I guess that you can acheive only premigrated state with dsmrecall tool
(two copies of file data - one on GPFS pool and one on external pool).
Maybe deleting 'dmapi.IBMPMig' xattr will do the trick but I don't think
it's safe, nor clean :).

Thank you in advance,
