Unmountable : not mounted?

[[email protected]]

I added this disk like a month ago. i'm not sure if there's any data on it. 

i can't click the check button as it's greyed out. it's currently doing a parity check.

i'm btrfs. so i need to restart in maintenance mode and run the check from the command line?

Are you sure it was ever formatted? Please post the diagnostics, that will also give an idea if it was previously formatted ort not.

As for the temperature alert, not much to do except check/improve the disk cooling.

i have 5 fans? lol and i've never had issues with cooling before in the past 2 years - was my point.

i have a supermicro 12 drive case with a ridic amount of fans.

 

this is not a pic of my actual machine but it is similar. there is a fan at the back of the machine and a fan on the CPU as well as the 3 fans in the drive bay area.

If it worked then it doesn't, the something broke.

 

I'd say either a fan failed or the way you control the fan did.

 

You'll have to investigate.

i mean, it was added to the array? i used to have 18TB free. now i have 5 something? it's a 12tb drive. it's brand new. i just bought it a couple months ago. sealed.

 

thank you for your help!

 

i'm not sure what to do about the drive. i can't click on the check filesystem status button

well, i had the top lid off the supermicro? maybe that messed up the airflow? all 5 fans are running. seems to be ok now w/ the lid closed. so far it is not overheating again.

That doesn't mean it was formatted, you need to manually format every disk after it's added to the array, but that's not the case here, the disk was formatted before, though based on the transid it was barelly used:

 

Jun  9 00:40:52 BIGASSNAS kernel: BTRFS: device fsid 0ce0630a-bf7e-4ce4-84f1-f598405bcb82 devid 1 transid 7 /dev/sdb1 scanned by udevd (1282)

 

Note 'transid 7', this is a very new and unused filesystem, compare for example with your other ones:

 

Jun  9 00:40:52 BIGASSNAS kernel: BTRFS: device fsid d9e9f710-02c9-41cb-bd9b-cfc93345fbc1 devid 1 transid 98843 /dev/sdc1 scanned by udevd (1289)
Jun  9 00:40:52 BIGASSNAS kernel: BTRFS: device fsid 33232feb-7c0b-4e3c-bbef-a0925aae03c4 devid 1 transid 1334443 /dev/sdg1 scanned by udevd (1289)
Jun  9 00:40:52 BIGASSNAS kernel: BTRFS: device fsid 41637979-6e3a-4dfc-a801-edcd1a8032b7 devid 1 transid 113884 /dev/sde1 scanned by udevd (1289)
Jun  9 00:40:52 BIGASSNAS kernel: BTRFS: device fsid 812a0302-1349-4d0e-9703-5291c65db4d8 devid 1 transid 19303823 /dev/sdd1 scanned by udevd (1289)

 

So if you just re-format pretty sure there wouldn't be much there, maybe nothing, but if you want to try and recover or confirm first there are some recovery options here.

Most probably that ; if there is a gap between the drives and the fan, the fan will not pull air through the drives but from the open space.
