[HLUG] BTRFS - no space left on device - or too full to delete

I had an interesting time this week.
i installed Timeshift which is a system restore tool that makes snapshots
of your entire os using rsync or Btrfs if you have it. Great idea I thought
that might get me out of a hole sometime ..
Well actually it left me in a bigger one :-(
Last night I experienced lots of weird goings on and found that there was
no space left on the root filesystem
But the usual trick of deleting stuff didnt help. I managed to boot into
another os I already had on a different HD on the pc.
This helped quite a bit. I'd installed the main os with Btrfs but ended up
with the situation that Timeshift had filled up my pc too much and I
literally couldn't delete files due to no space left.
I tried a rebalance and this didnt work . I tried the next technique of
making a dummy volume in btrfs as per
cannot run because the filesystem is full
Once I had the new loop volume i did another balance and this time it was
able to relocate 1 chunk out of 31 but this was enough to let me delete
files and rebalance again.
Moral of this story .. There's always a way to fix a problem in Linux
and sometimes trying to fix stuff just isnt worth it.
and lastly I really should read up more on Btrfs volumes sometime ;-)
