Hi, I've been searching the web, Google, mailing lists for a while now, but can't really find the answer - so I'm hoping for a 'SATA guru' here... On one of my server, I use 4 drive RAID5 Linux raid. One of the drives keeps reporting these errors: > Oct 1 10:11:29 bigxen2 kernel: ata1.00: exception Emask 0x10 SAct 0x0 > SErr 0x10002 action 0x2 frozen > Oct 1 10:11:29 bigxen2 kernel: ata1.00: (irq_stat 0x04400000, PHY RDY > changed) > Oct 1 10:11:29 bigxen2 kernel: ata1.00: cmd > 25/00:08:5c:be:60/00:00:14:00:00/e0 tag 0 cdb 0x0 data 4096 in > Oct 1 10:11:29 bigxen2 kernel: res > 50/00:00:6b:6a:60/00:00:14:00:00/e0 Emask 0x10 (ATA bus error) > Oct 1 10:11:30 bigxen2 kernel: ata1: waiting for device to spin up (7 > secs) > Oct 1 10:11:40 bigxen2 kernel: ata1: soft resetting port > Oct 1 10:11:41 bigxen2 kernel: ata1: softreset failed (1st FIS failed) > Oct 1 10:11:41 bigxen2 kernel: ata1: softreset failed, retrying in 5 secs > Oct 1 10:11:46 bigxen2 kernel: ata1: hard resetting port > Oct 1 10:11:47 bigxen2 kernel: ata1: SATA link up 3.0 Gbps (SStatus > 123 SControl 300) > Oct 1 10:11:47 bigxen2 kernel: ata1.00: configured for UDMA/133 > Oct 1 10:11:47 bigxen2 kernel: ata1: EH complete > Oct 1 10:11:47 bigxen2 kernel: SCSI device sda: 976771055 512-byte > hdwr sectors (500107 MB) > Oct 1 10:11:47 bigxen2 kernel: sda: Write Protect is off > Oct 1 10:11:47 bigxen2 kernel: sda: Mode Sense: 00 3a 00 00 > Oct 1 10:11:47 bigxen2 kernel: SCSI device sda: drive cache: write back As far as I can tell these happen randomly - sometimes it's 8 hours between two, sometimes it's a couple of minutes. There are about 5-20 of those per day, however Linux raid never kicks the drive out of the array. There are also no other signs of drive not functioning properly (such as filesystem corruption or similar). Any ideas? Can anyone 'decode' the above errors?
