[SOLVED] VMs disappeared after adding one ssd to cache pool and a parity disk - Version: 6.8.3

[bschron]

Hello, I am new to Unraid and was running with only 1 SSD at cache a 1 hard drive as a array.

Today I decided to add another ssd to the cache pool and one more HDD as a parity disk, but while the parity check was running suddenly all VMs stoped and now I reboot Unraid. After the startup all VMs were gone and every time I try to create a new one this messages shows up: "cannot create file '/etc/libvirt/qemu/Windows 10 - Larissa.xml.new': Read-only file system"

 

What should I do?

 

One extra issue, I tried stopping the array and it also does not work. It keeps displaying this message "Array Stopping•Retry unmounting disk share(s)...".

 

What should I do?

Cache pool is completely full, you need to move some data, it also has dual data profiles and it's not redundant, after you free up some space run a balance to raid1.

Beside what Johnnie said, it looks like you had a cache pool of 1x 240GB SSD. You then added a 120GB SSD to it.

Do you know that will immediately drop the amount of available space to 120GB (i.e. running in RAID-1)?

That explains why you suddenly ran out of space.

 

You might want to clarify what you were trying to do adding the 120GB to a pool with a 240GB if it was not an oversight.

Thanks, removing the file "solved"my problem for now.

Yes, this is still a bit confusing to me.

The idea is that I had 240gb on the cache and added more 120gb so I could have 360 total. Is this possible?

How do I mark it as solved?
