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 period retention-time [any]
What ist he name of the configuration file?
.snapshots.period ? That files does not seem human readable/editable.
hammer config /path/to/pfs
will show the contents on the conf file to edit it use
hammer viconfig /path/to/pfs
To delete a snapshot do I just delete the link and prune?
no thant won't work with ver 3
Either
snaprm path ...
snaprm transid ...
snaprm filesystem transid ...
(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.
OR
Edit config file and prune
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.
after pruning you need to reblock to gain space
hope this helps :-)
