This is the 3rd time in about a year. Have 2 other backup servers that were cloned from this one that have no problems. Done a couple kernel upgrades recently. Now has 2.6.18-2 kernel. It's based on Debian sarge. It's a low end Intel server motherboard using ata_piix sata driver. Have another mother board just like doing raid1 with sata drives that has had no problems but it has a much lighter disk load. smartctl has never shown any problems. In /sys/block/md2 did echo check > syncaction No error messages but mismatch_cnt is 1152. rc0/errors and rc1/errors are both 0. I'm guessing a hardware problem. Any suggestions?
