remove open directory from MDC

I'm upgrading my xSAN to mountain lion from 10.6.8. I'd like to stop using OpenDirectory on my controllers. I have my clients connected to my "real" open directory server and everything seems to work ok except I have warnings in xsan admin showing incorrect search policy. If I demote the mdc replica to standalone, xsan admin complains that it is not a replica. When I demote the mdc master to standalone OD, or connected to a OD, xSAN admin says it should be a OD master.

Is it possible to undue the original configuration to use OD? Or should I just leave it as configured and ignore the warnings?

Xsan 4 & TimeMachine incremental backup problem

Hi All ,

I've been trying to backup a Xsan 4 Volume (10.10.2) on promise vtrak E610F with no luck .
once I've been trying host the Time Machine backup drive on OS X Server 10.0.2 and use it on one of the Xsans' clients .
every time the backup finishes , the client is trying to backup the all Xsan volume again and no incremental with an error message "Backup volume is out of space , find another place to backup to... "
alternatively , I've tried to connect the backup Volume and run the backup direct from there ,
but again it's not backup it incrementally , and running out of space after it's first backup .
am I missing something about xsan4 compatibility ?

Kind Regards ,
Pr0d

backup

hi all,

I have roughly 100TB on xsan, and would like to backup this data onto another san. I'm wondering if there are software out there that does good compression with video files. Allocating another 100TB would be so costly, son wondering how does every backup their data.

thank you
