6.6.6/6.7.0 - System Kernal Panic One Parity Drive Swap

[SpyKiIIer]

Hello All,

 

I was running 6.6.6, and have updated to 6.7.0, and both versions have the same issue.  Most of my drives are 3/4TB drives, and one of my 4TB drives died.  I am trying to do the swap method to change the 4TB parity disk to a replacement for the 4tb that died, and make a new 8TB drive the new parity disk.  When I check the checkbox to start the process I see errors in the system logs, and then the system becomes unresponsive, requiring a physical restart to get access again.  Is there anything that can be done to fix this, or do I need to buy drives and copy all my content off, and remake the raid (not preferable).

Have you done a memtest recently?

[SpyKiIIer]

I have not, I will start it running tonight. And will update when complete.

I ran the memtest and it showed that there was a bunch of errors with the memory.  I have ordered replacement memory from Amazon and will swap it out and try again.

Sometime you get errors just because the memory modules are not seated properly.  Always worth checking for.

And don't use your server AT ALL until memory problems are fixed.
