If not fsck then what?

Yes, there are:
Mar 9 09:14:13 vhost03 kernel: end_request: I/O error, dev sda,
sector 1236929063
Mar 9 09:14:30 vhost03 kernel: end_request: I/O error, dev sda,
sector 1236929063
Mar 9 09:14:48 vhost03 kernel: end_request: I/O error, dev sda,
sector 1236929063
I am running an extended SMART test on the drive at the moment. I
suspect that the drive is probably at its EOL for practical purposes.
So likely we will be looking at an equipment upgrade given the age of
the rest of the equipment.
In the meantime what steps, if any, should I take to remediate this
problem?
