My friends, I have got an serious problem with SATA HDD running on CentOS Linux 5 (latest patched kernel 2.6.18).
My server often stops working. Although It can respond ping packets, I can not connect to any services. I review the server console, and see some error messages like: Nov 1 01:15:22 galgao kernel: SCSI device sda: 390719855 512-byte hdwr sectors (200049 MB) Nov 1 01:15:22 galgao kernel: sda: Write Protect is off Nov 1 01:15:22 galgao kernel: SCSI device sda: drive cache: write back Nov 1 01:15:22 galgao kernel: ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x0 Nov 1 01:15:22 galgao kernel: ata1.00: tag 0 cmd 0xb0 Emask 0x1 stat 0x51 err 0x4 (device error) Nov 1 01:15:22 galgao kernel: ata1: EH complete In normal conditions, I see these messages in "dmesg" results: ata1: EH complete ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x0 ata1.00: tag 0 cmd 0xb0 Emask 0x1 stat 0x51 err 0x4 (device error) I googled the phrase "ata1.00: tag 0 cmd 0xb0 Emask 0x1 stat 0x51 err 0x4 (device error)" and tried some instructions. However, the problem has not been solved. My server often still gets dump. Have you got any problem or something like this? And can you tell me a good solution? Thank you in advance.
