Re: [storage-discuss] Making zfs HA
I've heard about Nexenta. But we're just started to move away from another linux-build appliance, so I don't feel like start using another Linux once again. Hopefully, sometime we'll just order proper hardware from SUN to provide clustering or whatever is needed. Anyway, thanks for suggestions. Is it possible to use the code of plugins you've mentioned in Opensolaris? Anyway, it's still not a true clustering solution, but sounds promising. -- Roman -- This message posted from opensolaris.org ___ storage-discuss mailing list storage-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/storage-discuss
Re: [storage-discuss] Making zfs HA
All public plugins CDDL licensed, however they really depends on NMS and component APIs. More public plugins coming soon such us: UPS and ClamAV/ZFS - but also, this website can host projects which are related to OpenSolaris / Nexenta, such as kernel gate: http://www.nexentastor.org/projects/nexenta-gate Roman Naumenko wrote: I've heard about Nexenta.

[storage-discuss] Making zfs HA
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
Re: [storage-discuss] Making zfs HA
Hi Roman, take a look on what NexentaStor is providing: auto-cdp - a commercial plugin which simplifies significantly ZFS/AVS management of primary/secondary hosts auto-sync - a free service which supports sophisticated ZFS send/recv over SSH, NC. Or use send snapshots over RSYNC - which could be ideal for clouds. This service can be ideal solution for asynchronous ZFS replication auto-tier - a free service which supports RSYNC tiering. This service works really well as a second tier archiving solution. Think of Netapp over NFS periodic backups, etc the development portal is http://www.nexentastor.org - the place where NexentaStor open source developers and Partners getting together, so this can provide you a free community support for open sourced plugins.
