(HAMMER VERSION 3+) Remove a snapshot given its softlink or transaction id. If specifying a transaction id the snapshot is removed from file system meta-data but you are responsible for removing any related softlinks. If a softlink path is specified the filesystem and transaction id is derived from the contents of the softlink. If just a transac- tion id is specified it is assumed to be a snapshot in the HAMMER filesystem you are currently chdir'd into. You can also specify the filesystem and transaction id explicitly.

Snapshots maintenance
How does one adjust the number of snapshots for hammer to keep? In the man page it says: HAMMER version 3+ The configuration file is saved in file system meta-data The format of the configuration file is: snapshots[any] What ist he name of the configuration file? .snapshots.period ? That files does not seem human readable/editable. Also the man page has: "see hammer config." Is that another section in the man page or another man page? Tried man 5 hammer and searchign for "hammer config" in the main man page. To delete a snapshot do I just delete the link and prune? Example I deleted a few links from /var/hammer/root and then did hammer prune /var/hammer/root Got TID 000106239300 - 0001062e2490 TID 000104c82520 - 000106239300 TID 000104a207b0 - 000104c82520 TID 0001043d8dd0 - 000104a207b0 TID 0001040614a0 - 0001043d8dd0 TID 000103616010 - 0001040614a0 TID 0001028fb580 - 000103616010 TID 0001028d5dc0 - 0001028fb580 TID 0001020f72d0 - 0001028d5dc0 TID 0001 - 0001020f72d0 Prune //: 10 snapshots Prune //: objspace 8000: 7fff: pfs_id 0 Prune //: prune_min is 0d/00:00:00 Prune // failed: Input/output error < Error? Pruned 0/0 records (0 directory entries) and 0 bytes Don't see any difference in df. When/how is the space regained? Had a lot of extra data so now that I cleaned things up I want to delete the snapshots with the extra data to get the space back.
