Unlinking a fileset
A junction to a fileset is removed with the mmunlinkfileset command, which unlinks the fileset only from the active directory namespace. The linked or unlinked state of a fileset in a snapshot is unaffected. The unlink fails if there are files open in the fileset, unless the -f option is specified. The root fileset cannot be unlinked.
After issuing the mmunlinkfileset command, the fileset can be re-linked to a different parent using the mmlinkfileset command. Until the fileset is re-linked, it is not accessible.
Note: If
run against a file system that has an unlinked fileset, mmapplypolicy will
not traverse the unlinked fileset.
Attention: If you are using the IBM Spectrum Protect™ Backup-Archive client you must use caution when you unlink filesets that contain data backed up by IBM
Spectrum Protect. IBM
Spectrum Protect tracks files by pathname and does not track filesets. As a result, when you unlink a fileset, it
appears to IBM
Spectrum Protect that you deleted the contents of
the fileset. Therefore, the IBM
Spectrum Protect Backup-Archive client inactivates
the data on the IBM
Spectrum Protect server which may result in
the loss of backup data during the expiration process.
For complete usage information, see mmunlinkfileset command.
