2 Disabled disk while reconstructing a replacement drive

[eric4414]

Using Unraid for a while but first big issue for me.  First time posting anything.  My goal is to replace a 2GB drive with a 10.  I precleared the new drive with no issues.  I changed disk10 to use the new drive and restarted the array.  It started okay and was emulating and reconstructing disk10. Looked the same as I've done before in the past.   I didn't check on it for a while and noticed I have 2 disks disabled.  I have 2 parity disks so the array is working unprotected right now.  The only thing I did after the successful preclear and before the disk config change was to change a broken fan.  Maybe I wiggled something??  My thought is to power down and reset cables.  But I thought I'd reach out for some advice before I did.  Plus I'm a little unclear as to how to get the drives back to enabled state when I have 2 of them with the issue.  Any help is appreciated.

Thanks, Eric.

Syslog is missing the last days, reboot and post new diags after array start.

Rebooted.  Here's the latest diagnostics.

Thanks,

Eric.

Disks look fine, you're using SASLP controllers, these are not recommended for a long time and known to drop disks without a reason, if possible replace them with LSI HBAs.

Thanks.  I'll take a look at a replacement controllers.

So it sounds like my next course of action would be to follow the procedure to Rebuild a drive onto itself.  Does that sound right?  Also, should I rebuild both disabled disks at the same time?

Yes, if you're going to replace the controllers soon I would do it after, you can do both at the same time, no extra risk since they are already disabled.
