Hi,

 

I started an array rebuild recently when one of my 4TB HDDs had issues.  It was a SATA 4TB drive and I replaced it with a 6TB SAS drive (Dell PERC H310 cross-flashed to IT mode).  However, shortly after I started the rebuild I lost access to the WebUI.  I figured no big deal, I still have SSH access to monitor the progress of the rebuild using 

mdcmd status | egrep "mdResync"

Of course, I have no lost SSH access into the server.  My switch still shows an active physical connection but the Meraki dashboard shows no traffic to or from that port in over a day now.  Do I want the 1 day 16 hours it was estimated to take to finish then do a hard power off and pray its done or is there another way I can shut it down and not have it do a parity check right away?  I'd check the console, but it is a headless server so that makes it difficult.

When the rebuild is done type:

poweroff

That would be great, but I have no way of knowing if the rebuild is done. I can connect a keyboard, login and hope it's done and do a power off. But I dinner like that idea. I should have hooked one of my data drives to the onboard SATA controller, but I didn't. 

Sorry, missed the part you lost ssh access, try with a monitor and keyboard and check mdcmd status, failing that check for disk activity

I can drag a monitor downstairs, just didn't want to.  I guess I will tonight and hope it's done.  I think I will also swap a data drive to the onboard SATA controller instead of the H310 just so I have an HDD activity light for stuff like this.

Saw this when I hooked a monitor up.  Any ideas?

I figured out the issue.  It was the fact that I had my shucked 10TB WD HDD plugged into my new Mini SFF 8087 to 4X SFF 8482 Cable.  Even though the power connector going into it didn't have a 3.3v line, the pin being connected to the drive was enough to mess it up.  Working fine now.  Other than my SSD not wanting to trim, but I'll figure that out another day.
