Unable to format new drive

[Nodiaque]

Hello,

 

I'm on unraid 6.9.2 with an array of 5 drives. I've bought 2 new drives that I pre-clear and now I added to my array (extending to 7 drives). But it keep saying Unmountable: Unsupported partition layout. When I check Format, it says formatting and goes back to the same unmountable state. What am I doing wrong? Partition type was at auto, I tried with xfs selected and didn't change.

 

Thank you

You are likely to get better informed feedback if you post your system’s diagnostics zip file.

no problem, here it is. I'm reading though that I might be doing something wrong since I'm gonna remove one of the hdd in the array, I was gonna copy the content then remove it, but it seems I must use another replacement procedure that rebuild the array. But still, I need to have it format for it to work

ok, one of them is now formatted and I did nothing... I guess the process is running in background with nothing showed on the ui?

[Nodiaque]

the other one doesn't seem to want to be formatted though

The diagnostics showed you successfully formatting disk5.   If this is a different disk then post new diagnostics.

[Nodiaque]

should be disk 6

Cannot see any attempt to format disk6 in those diagnostics.   All I can see is it being partitioned.

[Nodiaque]

hmmm... maybe in this one. my gui showed formatting for about 10 minutes before reverting to unmountable

from what I seems to gather from the syslog, it clear the disk, format, create partition then failed to mount it.

I manage to do it. I had to take down the array, start the array in maintenance mode then format. Don't know why it was failing

Unrelated but your CPU is throttling due to overheating:

 

Jun 22 15:59:52 ServRaid kernel: mce: CPU26: Core temperature is above threshold, cpu clock is throttled (total events = 78)
Jun 22 16:00:00 ServRaid kernel: mce: CPU12: Core temperature is above threshold, cpu clock is throttled (total events = 78)

 

Check/clean cooler.

In fact it's ok. I was doing some heavy encoding a cpu reached 80c. But now it's sitting at 25c and it's still throwing these message, which is weird.

Are you positive you are monitoring the correct sensor? Sometimes the names are misleading.

[Nodiaque]

Yeah, I have a graph with the temp of all cores. CPU is sitting idle running right now between 40 and 50C. Everytime I start to have CPU throttling, it never stop until I restart unraid. Don't know why, and it happen when I run FileFlows using all CPU/Core. I don't monitor CPU hz, I should check that. I'm not even sure my CPU support throttling
