I have a machine with 4 hard drives. I run smartctl -d ata -t long /dev/sdx (where x is a, b, c or d) once a week. This all used to work fine, but lately the time required for sdb and sdd has increased greatly. For example, for sdd smartctl tells me Extended self-test routine recommended polling time: ( 163) minutes. but the current test has been running for 3.5 days and is only 50% done. The tests generally do complete, and have never shown errors. Both sdb and sdd are Seagate Barracuda 500G SATA NCQ 16MB cache 7200rpm 7200.10 Full smartctl -a output below. The two drives without problems are older, smaller drives. Kernel 2.6.28, oldish version of Debian. Any idea what could be happening? If this isn't the best list to ask on, please recommend another.

Is the disc more active at the time? Is it possible, that you do an umount, before starting the test? HTH & cheers, Gabriele |

So I don't think this is the issue. But if no other solution is found, I'll trying booting from rescue media and re-trying the test just to be sure. Also, I should have said that the disks are partitioned, and the partitions are assembled into various RAID arrays some of which have lvm running on top of them. Best, Dan |
