Hello list, What are the options for building clustering storage using opensolaris? I'm interested in HA solutions.
I tried only one option - AVS replication. Unfortunately, AVS configuration is too complicated. Groups, bitmaps, queues, rcp timeouts, slicing - it's just a nightmare to make it work and support in production when there are more that a couple of pools. And probably it's gonna be slow if there are jbods attached to a storage controller, or will require half of Ethernet ports to replicated more or less reliably. 10Gige interface for it - did anybody try? Another option I'm looking into is sending snapshots. But regardless what we've heard from sun - it's gonna slow down zfs operations. Creating a snapshot is not quick on loaded pool, especially if storage controller manages many pools. So, it's probably dozens of minutes delays in transferring snapshots over to a standby server. -- Roman -- This message posted from opensolaris.org _______________________________________________ storage-discuss mailing list storage-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/storage-discuss
