For what I know, Nexenta uses a commercial HA implementation called RSF-1 for their HA clusters. AFAIK RSF-1 makes sure only one 2 heads every actively imports the ZFS pool in question because ZFS is not a cluster-aware FS. (right?).
So their way of doing HA heads is by sharing the disk shelves between 2 heads, not replicating the content between 2 systems. I don't know how others do (me being on a consumer perspective). I don't know how others do. > I thought the ZFS mirror on separately hosted iscsi targets was going to be a > great idea ... it turns out it's only great at destroying your pool... iSCSI is not a shared storage and if you write to the same disk/lun from 2 initiators without "something in between" like DRBD (Linux), AVS, or HAST (FreeBSD) things are really expected to cause problems or call other evil dragons. :-) > In linux, there's drbd (which has its own limitations)...

Why AVS doesn't seem to be actively continued and used by consumers, I don't know, perhaps more technical people can answer this. -- Mat ------------------------------------------- illumos-discuss Archives: https://www.listbox.com/member/archive/182180/=now RSS Feed: https://www.listbox.com/member/archive/rss/182180/21175430-2e6923be Modify Your Subscription: https://www.listbox.com/member/?member_id=21175430&id_secret=21175430-6a77cda4 Powered by Listbox: http://www.listbox.com
