Does the Slave pfs take up more space that the Master?

[Sdävtaker]

What i remember happened to me was that master pfs are pruned/reblocked by the periodic but the slave pfs are not, so time to time i used to get a lot of used space in my backups, just go and prune/reblock by hand and check if thats what happening to you, check the config before, so you sure not deleting stuff you dont want to.

Hi,

I have two hammer file systems.

Backup1                   454G   281G   173G    62%    /Backup1
Backup2                   454G   316G   138G    70%    /Backup2

on a 2.7-DEVELOPMENT DragonFly v2.7.0.54.g0754fe-DEVELOPMENT #18: Wed Apr  7

Backup1 contains 3 pfses

dfly-bkpsrv# cd /Backup1
dfly-bkpsrv# ls -l
total 0
drwxr-xr-x  1 root  wheel  0 Mar 26 13:38 Data
drwxr-xr-x  1 root  wheel  0 Apr  5 15:36 VersionControl
drwxr-xr-x  1 root  wheel  0 Oct  8  2009 pfs
drwxr-xr-x  1 root  wheel  0 Feb  3 09:46 test

Backup2 contains just the mirrored slves of the above 3 pfses

dfly-bkpsrv# cd /Backup2
dfly-bkpsrv# ls -l
total 0
lrwxr-xr-x  1 root  wheel  17 Jul  7  2009 Data -> /Backup2/pfs/Data
lrwxr-xr-x  1 root  wheel  27 Sep 28  2009 VersionControl ->
/Backup2/pfs/VersionControl
drwxr-xr-x  1 root  wheel   0 Oct  8  2009 pfs
lrwxr-xr-x  1 root  wheel  17 Oct  8  2009 test -> /Backup2/pfs/test

the snapshots are the same as of now for both masters and slaves

So why Backup2 70% filled while Backup1 is only 62% filled ?

Thanks :-)
