Disc offline and read errors


Recommended Posts

Back story - had some renovations done over a few days and server was offline for most of it. Once renovations were completed I took my server outside and blew it out to clean it and set it all back up. Been running for a day or two no issues. Woke up this morning with read errors on one disk and no another disk has gone offline. I am thinking cables but I need to check with you guys first before powering down and reseating cables.

sdh drive seems to have issues:

This can be cable, but also the disk itself, or the controller..

Reseating the cable is the first thing to do.

Reseated all cables, power sata and mini sas.

Nothing appeared loose.

Powered back up, stopped the array, removed the errored disk, started the array, stopped the array, added the errored disk back in and started the array.

Now i am waiting for the parity sync / rebuild to complete so we will see what happens when / if it happens.
