Hardware failure

It’s been a while since I updated my blog. Have had serious problems with my main server in Sweden. It started to halt/stop on randon occations. The screen just went black. When I examined the logs I could see the following:

Mar 11 04:22:17 server2 kernel: ata1.00: (BMDMA stat 0×20)
Mar 11 04:22:17 server2 kernel: ata1.00: tag 0 cmd 0×25 Emask 0×9 stat 0×51 err 0×40 (media error)
Mar 11 04:22:17 server2 kernel: sd 0:0:0:0: SCSI error: return code = 0×08000002
Mar 11 04:22:17 server2 kernel: sda: Current: sense key: Medium Error
Mar 11 04:22:17 server2 kernel: Additional sense: Unrecovered read error – auto reallocate failed
Mar 11 04:22:17 server2 kernel: end_request: I/O error, dev sda, sector 1305413389
Mar 11 04:22:17 server2 kernel: ata1: EH complete
Mar 11 04:22:17 server2 kernel: SCSI device sda: 1465149168 512-byte hdwr sectors (750156 MB)

It is evidently obvious. Either the Hard disk controller or one of the harddisk are slowly failing.

I have fixed the read error by marking those sectors bad. But this was a serious warning that made me order a brand new server. It will be installed sometime during this week.

At present the server is holding up and it is in operation knock on wood.
