Hi Folks,

 

I had to rebuild my server with different hardware because my old MB crapped out. In any case, it seemed to have started fine but my devices showed up as missing, and when I tried to add them into the correct slot it showed up as wrong (it was not). I read another thread about this issue and went with the advice of doing a "New Config" and "Retain All". That seemed to have worked as all disks showed up correctly and array working.

 

After that I had to restart the server and upon restart the same problem appeared, so I did the "New Config" again with "Retain All" but this time all devices showed up as unassigned? I'm kind of stuck now as I have no idea what the correct device order was/is/should be. What should I do at this point? Is there a log or history somewhere I can look up the correct device order?

 

Help is greatly appreciated.

Do you have any old diagnostics saved or posted on the forum? Are you using single or dual parity?

NO diagnostics saved. I did find a photo I took of it today though and were able to put them in the right order. It's dual parity.

I did initiate a parity check after that, and hopefully it will work after that.

So while running the parity check, a bunch of read errors started to pop up on several devices. Does this mean my drives are toast or should I look for a hw problem at this point? I will let the parity check finish first. Log attached.

Edit: Should I cancel the parity check? There are a lot of sync corrections, and I am not sure if that's related to the previous issue or the read errors.

Disks look fine, and the errors happened on all five disks at the same time, which virtually rules out a disk problem, check all connections especially anything shared by those disks, like power cable, backplane region, etc, could also be a PSU issue, unlikely to be controller related since they are using two different controllers.

I replaced a power cable and all is back to normal. Thanks a lot guys, really appreciated the help. One last question, is it prudent to run another parity check after this?

 

Oh and one last question, I have added a second SSD for the cache drive. It does say it is part of the cache pool but it still only showing 500gb total. It's probably something silly, sorry.

It's fine, but always run a non correcting check (unless sync errors are expected).

Default profile is RAID1, so usable space will be the same, but it can be changed.
