Couple months, nope. I guess there is this DOS utility provided by WD that allows you change TLER settings having TLER disabled can be problem, faulty disks timeout randomly and zfs doesn't always want to mark them as failed, sometimes it does though.

Yes, I'm aware of the issue, and am using 16x RE4 drives in my current box right now (which I unfortunately had to convert to CentOS 5.3 for Oracle/ custom software compatibility reasons). I've made very bad experiences with Seagate 7200.11 in RAID in the past.

The very leading-edge hardware is sometimes not supported, but I've been using http://www.supermicro.com/products/motherboard/QPI/5500/X8DAi.cfm in above box. > anything that's been out for a while should work fine.

Yes, dual-socket quadcore Xeon. -- Eugen* Leitl <a href="http://leitl.org">leitl</a> http://leitl.org ______________________________________________________________ ICBM: 48.07100, 11.36820 http://www.ativel.com http://postbiota.org 8B29F6BE: 099D 78BA 2FD3 B014 B08A 7779 75B0 2443 8B29 F6BE _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss ______________________________________________________________________ This email has been scanned by the MessageLabs Email Security System.
