Hello.
Some time ago, about a year, I set up a RAID 5 with three 2TB Seagate SATA II discs, using the RAID controller which comes with the IDH67BL board. This was for a home server runnin Ubuntu server 12.10.
Yesterday, the server stopped booting ...
Yesterday, the server stopped booting ...
After booting with a live cd, I could see that SMART check of one of the disks was reporting bad sectors and that have had overheating in the past ...
I ran the SMART self-test for the three discs and two reported as OK, with one reporting as failed ( read errors ).
From the live cd I can mount the RAID, but when I try to access some files, it gives me a read error ....
My questions are:
1. If only one drive is reporting errors: why the machine is not booting and I can't access the data? Doesn't a RAID5 should keep working but in a degraded mode?
1b. Does this mean that surely one of the other discs also have problems?
2. How can I be sure that the data of the two disks, for which the SMART self-test reports as OK, its really OK?
3. What would be the steps to restore the RAID (if it is possible at all)? Is it enough to remove the failed disk and install another ?
Thank you very much .
