Maintenance of mirrored filesystem

[John R. Shannon]

I setup hammer filesystems on identical disk drives. I created a number
of PFS that are mirrored. Over time, the storage allocation on the
MASTER has remained constant while it continues to grow on the SLAVE as
shown in the following:

MASTER                   5588G  1456G  4132G    26%    /master
SLAVE                    5588G  2775G  2813G    50%    /slave
/master/pfs/@@-1:00002   5588G  1456G  4132G    26%    /master/backups/dns
/master/pfs/@@-1:00001   5588G  1456G  4132G    26%
/master/backups/colleen
/master/pfs/@@-1:00003   5588G  1456G  4132G    26%
/master/backups/domain0
/master/pfs/@@-1:00004   5588G  1456G  4132G    26%    /master/backups/imap
/master/pfs/@@-1:00005   5588G  1456G  4132G    26%    /master

...

Am I missing a maintenance step that needs to be performed on the slave?

My daily run output shows:

HAMMER maintenance:
cleanup /                    - handle PFS#0 using /var/hammer/root
           snapshots - run
               prune - run
           rebalance - run..
             reblock - run....
              recopy - skip

           snapshots - run
               prune - run
           rebalance - run..
             reblock - run....
              recopy - skip
cleanup /master/backups/dns  - handle PFS#2 using
/var/hammer/master/backups/dns
           snapshots - run
               prune - run
           rebalance - run..
             reblock - run....
              recopy - skip

... (for each PFS)

The mounts all represent the master PFS as the slave PFS are not mounted.
