I've been running my unraid server without any issues for a few years now.  About 3 months ago, I upgraded to 5.0rc and have been running fine as well.  I'm currently on 5.0rc11 and been on it for about 2 months.

 

Last night, I was trying to access my server to copy some files on it and received an error and it was going into read-only.  I don't really recall the error since I assumed it was a fluke and I just needed to reconnect to it.  Boy was I wrong!

 

I went to the web dashboard to stop the server and start it again hoping that would fix it but when I stopped it, one of my drives went missing. Clicking on the drop down menu showed no available disks so I assumed the disk had gone bad and just needed to be replaced.  Luckily, I had a spare sitting around and decided I would just  shut it down and install the new drive the following day.

 

The next day, I boot it up just to make sure the drive was still missing but now though two disks are missing!!! So here I am now, freaking out, because I know two disks missing is very bad.

 

I've attached my syslog and hope something can be figured out. If there is something else that is needed, please let me know.

Check the serial numbers and the disk connections. It sounds like the wrong disk was replaced or the connections are not attached.

This seems to have fixed it.  Something must of come loose since I haven't really touched the server.  Anyway, I pressed in all the SATA connections, turned it back on and everything is green again!

 

Thanks dgaschk!

FWIW, reseating the connections has fixed EVERY issue like this that I've seen on UnRAID for the 5 UnRAID servers I use or help with [2 of mine plus 3 friends] over the last 4 years.

 

I think that with time the connections can get very slightly off due to normal drive vibration ... especially with the 5-in-3 drive cages [i've never had a problem with drives using dedicated locking SATA connectors.

I moved about a month ago too so I'm sure that did not help. Anyway, all is green again

I'd run a NONCORRECTING parity check to be sure, but, good.
