Please reboot and post new diags after array start.

Filesystem is going read-only due to lack of space, but I'm not seeing why it's running out of space at mount time, this usually happens when a balance was started but not signs of "balance resumed" in the log, in any case please try this, with the array stopped type:

 

mkdir /temp
mount -o skip_balance /dev/sdf1 /temp
btrfs balance cancel /temp
umount /temp

 

Then start the array and post new diags.

Seems to be working now.

 

Here are the logs.

Yes, kooks OK now, note that the pool is in single profile, i.e., no redundancy but you can use the total capacity from both devices, if you want to convert to raid1 (redundant but only 120GB can be used since they have different capacities) you first need to remove some data from cache1.

Its working again.
