Comment 9 for bug 1931790

I tried as in[1]:

  btrfs filesystem resize max /path/to/mount

It did resize, but it is still not working with 5.11 kernel, had to go back to 5.8.

> The other alternatuve solution which I discovered the hardway is to break one of the disks (In my case, I rebuilt both disks one after he other due to some issues) and re-add it and rebuild to see if that solves..

Can you write specific steps? I understand that needs to happened on working kernel. Surprisingly I have two raid1 devices. The root is working fine, however the other one mounted at /mnt is not.
