Re: [Samba] CTDB with 3 nodes and local disks without a dedicated SAN
Hi Daniel, thank you very much for your fast answer! you should try iscsi drbd gfs if you think and mix wisely it should start. THis is, you have on central point of storage where all three nodes write to and this storage backed up. wouldn't I have one single point of failure then (in terms of HA) or did I get something wrong? My latest try with ctdb did not work on CentOs. The package was brocken. Good to know, thanks, I'll compile it from source then as I also run CentOS 5.5, wanted to use 3.5 anyway. And I think it is not possible to cluster a DC. Could you elaborate more on this? Do you mean it's not possible to cluster samba acting as a DC? If that's what you're saying and it's true I must have missed the biggest point. I'd like to set up 3 samba nodes clustered with CTDB, with each node/machine having its own sets of local disks. It would be great if 2 machines and/or sets of local disks could fail the same time without taking down samba. Is this only possible using DRBD as suggested in the current Samba 3 book? The book by Volker Lendecke, Karolin Seeger, Björn Jacke and Michael Adam. Maybe it's only available in German, I don't know.

Yes. Maybe you could use a distributed, replicated filesystem like Ceph. Not sure though. I've never used ctdb or Ceph. -- Michael Wood esiot...@gmail.com -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/options/samba
[Samba] CTDB with 3 nodes and local disks without a dedicated SAN
Hello, First, sorry, I know that this is by far not 100% samba related but since this setup is exclusively for samba + CTDB and as such is no ordinary setup, I thought it might be good to ask here. I'm having a hard time figuring out how to accomplish the following: I'd like to set up 3 samba nodes clustered with CTDB, with each node/machine having its own sets of local disks. It would be great if 2 machines and/or sets of local disks could fail the same time without taking down samba. Is this only possible using DRBD as suggested in the current Samba 3 book? As I understand DRBD only allows 2 nodes and an optional 3rd for disaster recovery. Does anyone have any idea or recommendations on how to do this without DRBD's limitation of 2 storage nodes? Thank you very much for any help! Regards, Max -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/options/samba
