I am also running 2 of the Supermicro cards. I just upgraded to b126 and it seems improved. I am running a large file copy locally. I get these warnings in the dmesg log. When I do, I/O seems to stall for about 60sec. It comes back up fine, but it's very annoying. Any hints? I have 4 disks per controller right now, different brands, sizes, everything. New SATA fanout cables and no expanders.
The drives on mpt0 and mpt1 are completely different, 4x400GB Seagate drives, 4x1.5TB Samsung drives. I get the problem from both controllers. I didn't notice this till about b124. I can reproduce it with rsync copying files locally between ZFS filesystems and with --bwlimit=10000 (10MB/sec). Keeping the limit low does seem to help. --------------- Oct 31 23:05:32 nas scsi: [ID 107833 kern.warning] WARNING: /p...@0,0/pci10de,7...@10/pci10de,5...@0/pci10de,5...@3/pci15d9,a...@0 (mpt1): Oct 31 23:05:32 nas Disconnected command timeout for Target 7 Oct 31 23:09:42 nas scsi: [ID 107833 kern.warning] WARNING: /p...@0,0/pci10de,7...@10/pci10de,5...@0/pci10de,5...@2/pci15d9,a...@0 (mpt0): Oct 31 23:09:42 nas Disconnected command timeout for Target 1 Oct 31 23:16:23 nas scsi: [ID 107833 kern.warning] WARNING: /p...@0,0/pci10de,7...@10/pci10de,5...@0/pci10de,5...@2/pci15d9,a...@0 (mpt0): Oct 31 23:16:23 nas Disconnected command timeout for Target 3 Oct 31 23:18:43 nas scsi: [ID 107833 kern.warning] WARNING: /p...@0,0/pci10de,7...@10/pci10de,5...@0/pci10de,5...@3/pci15d9,a...@0 (mpt1): Oct 31 23:18:43 nas Disconnected command timeout for Target 6 Oct 31 23:27:24 nas scsi: [ID 107833 kern.warning] WARNING: /p...@0,0/pci10de,7...@10/pci10de,5...@0/pci10de,5...@3/pci15d9,a...@0 (mpt1): Oct 31 23:27:24 nas Disconnected command timeout for Target 7 -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
