Cache Drive not using full 1TB Disk

With the array stopped completely wipe the device with:

blkdiscard -f /dev/nvme1n1

Then start array and re-format, that should fix it.

I did this and I am still only showing a disk size of 537MB 

 

Also, attached diagnostics.

 

 

Thanks for the help.

Run it again with the array stopped and post the output.

Okay, so I stopped the array ran 'blkdiscard -f /dev/nvme1n1' and this was the response 

 

root@Server1:~# blkdiscard -f /dev/nvme1n1
blkdiscard: Operation forced, data will be lost!
root@Server1:~#

Now post the output of

fdisk -l /dev/nvme1n1

root@Server1:~# fdisk -l /dev/nvme1n1

Now start array and format.

[Austin Detzel]

Still no luck only 537MB, seems really strange. Everything detects the 1TB disk but it wont useit.

Very strange, post again the output of:

fdisk -l /dev/nvme1n1

 

[Austin Detzel]

Sure thing

That looks correct, please reboot in case there's something still in RAM about the old layout.

[Austin Detzel]

Full Reboot, and no luck

[JorgeB]

Post new diags after rebooting and the output of fdisk.
