I spoke to soon, turning off NCQ helped dramatically, it worked three times!
writing to raid10 dd: writing `file2': No space left on device 1430328+0 records in 1430327+0 records out 1499806973952 bytes (1.5 TB) copied, 3914.51 s, 383 MB/s Fri Dec 5 06:00:25 EST 2008 writing to raid10 dd: writing `file2': No space left on device 1430328+0 records in 1430327+0 records out 1499806973952 bytes (1.5 TB) copied, 4063.25 s, 369 MB/s Fri Dec 5 07:08:11 EST 2008 writing to raid10 dd: writing `file2': No space left on device 1430328+0 records in 1430327+0 records out 1499806973952 bytes (1.5 TB) copied, 3926.71 s, 382 MB/s Fri Dec 5 08:13:41 EST 2008
Then it crashed again, with NCQ enabled, it would not even complete one test, So basically a new system, new PSU, new cables, its on a new APC UPS and the problem persists even when all disks are on a RAID card, SW raid, it does not matter, Velociraptors have problems, I think its time for me to get regular 1TiB disks and be done with it.
