Change Raid | Can't Delete Storage Pool

Post by xpesrx »

I have a new TNAS and in setting it up, I ended up with a RAID 5. Now, before anything is on the nas, I am trying to change my RAID from 5 to 6.
I delete the volume then I go to delete the storage pool but as soon as I do, it pops back up? Edit and Create are grey'd out.

Please advise.

When you delete a storage pool, what is prompted?
You need to delete the storage pool before creating a new RAID.

No prompts. It does tell me something about nothing being saved and to confirm leaving when I tell it to delete the volume but I dont see a button where I can save what I've done (deleting the volume) anywhere. See video here: https://youtu.be/DxfZ0IedRmU

Hello, I am experiencing the same issue where I cannot delete a Volume (which means I also cannot delete a Storage Pool) on my TNAS (F5-421).

I have followed your instructions above to login using SSH, but when I try running this command:

umount /mnt/md0
umount /home

I get this error message in Putty:

umount failed: Operation not permitted.

Can you please help me to be able to delete my Volume?

If you are using TOS 4.x, you need to switch to the root user to execute the command.

Code: Select all

sudo -i
