So I've got an OMV 3.x server that I made out of an old dell PE 840, with 4 2TB drives in the Dell SAS Raid enclosure. Over the weekend a VM that I have on it failed. When i checked it out found tons of 'medium errors' and 'unrecoverable read errors'. I assume it's 'bad blocks' so first and foremost, how do I run a 'scandisk' or something on this to recover what it can?
Second would be, is there a way to get notified of errors like this? I think if I could have moved this before it got bad I wouldn't be in a pinch now so i figured I'd check for my other systems and future reference...
Thanks!
