Can you give me a one liner on plugs and HA in a S4 context? We'd like to have a spare box with a backup of the data to substitute the DC/fileserver. What do you think about the possibility of syncing the data over to the secondary DC along with a copy of smb.conf and using that when the primary DC/fileserver goes down. Would the clients know to use the new fileserver: thinking about Kerberos here.

Re: [Samba] Samba4 Can we use two file-servers?
To have your data high available put it on a replicating GLUSTER vol (glusterfs-as many Fileservers as you want). Or replicate it with drbd master master (if 2 DCs are the limitation) Good Luck Daniel --- EDV Daniel Müller Leitung EDV Tropenklinik Paul-Lechler-Krankenhaus Paul-Lechler-Str. 24 72076 Tübingen Tel.: 07071/206-463, Fax: 07071/206-499 eMail: muel...@tropenklinik.de Internet: www.tropenklinik.de --- -Ursprüngliche Nachricht- Von: samba-boun...@lists.samba.org [mailto:samba-boun...@lists.samba.org] Im Auftrag von steve Gesendet: Dienstag, 26.

HA is High Availability, put (over) simply, the provision of backup devices/components in case of failure. Daniel mentioned in another reply, you can use GlusterFS (NAS type approach) to aggregate your data (you still need somewhere to aggregate it to though) or replication if your restricted to the two DCs, though I've never tried that approach. In either case the switch (of where data is accessed) should be automated from a client perspective.
