It didn't work for the slave pfs because

/Backup2/www-5mbak/www-hot was a symlink to  /Backup2/pfs/www-hot/

When you share /Backup2/www-5mbak/ using samba you will see an icon
for "www-hot" and all the snapshots but you cannot access them because
they are not directly under the directory sahred using samba so I did
the following

Destroyed the pfs /Backup2/pfs/www-hot/

and created it in


dfly-bkpsrv# ls -l /Backup2/www-5mbak/www-hot
lrwxr-xr-x  1 root  wheel  31 Apr 23 14:28 /Backup2/www-5mbak/www-hot
-> /Backup2/pfs/www-5mbak/www-hot/

and shared


using samba.

And set the snashot directory to it


But the problem I face is that.

mirror-stream mirrors all the 5 minutes snapshots from the Master.

On the slave pfs my config is

dfly-bkpsrv# hammer config /Backup2/www-5mbak/www-hot/
snapshots 1d 2000d
prune     1d 5m
rebalance 1d 5m
reblock   1d 5m
recopy    3d 10m

for the daily snapshots with a prune-min=2d

So it seems the 5 min snapshots will never get removed during cleanup.

So I guess I will have to configure the 5 mins snapshots on the slave
and the daily snapshots on the Master to adjust things?
