Re: [zfs-discuss] strange pool disks usage pattern

By the way, there are more than fifty bugs logged for marevell88sx, many of them about problems with DMA handling and/or driver behaviour under stress. Can it be that I'm stumbling upon something along these lines? http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6826483 Maurilio. --

Re: [zfs-discuss] strange pool disks usage pattern

Richard, it is the same controller used inside Sun's thumpers; It could be a problem in my unit (which is a couple of years old now), though. Is there something I can do to find out if I owe you that steak? :) Thanks. Maurilio. -- This message posted from opensolaris.org _

Re: [zfs-discuss] strange pool disks usage pattern

Carson, they're seagate ST31000340AS with a firmware release CC1H, which from a rapid googling should have no firmware errors. Anyway, setting NCQ depth to 1 # echo zfs_vdev_max_pending/W0t1 | mdb -kw did not solve the problem :( Maurilio. -- This message posted from opensolaris.org __

Carson, the strange thing is that this is happening on several disks (can it be that are all failing?) What is the controller bug you're talking about? I'm running snv_114 on this pc, so it is fairly recent. Best regards. Maurilio. -- This message posted from opensolaris.org
