Your server has issued one or more call traces

Cache filesystem is almost completely allocated, though it does not look fully allocated and call traces if it was are unusual, still it should be balanced, especially since it has dual data profiles, you should be getting a system notification about that, before starting best to backup anything important on the pool just in case, then run 1st:

 

btrfs balance start -dusage=75 /mnt/cache

 

and when done run:

 

btrfs balance start -dconvert=raid10 /mnt/cache

When it finishes check that the single profile is gone:

@johnnie.black when I try to run the second part of your instructions

btrfs balance start -dconvert=raid10 /mnt/cache

I get the following

ERROR: error during balancing '/mnt/cache': Invalid argument
There may be more info in syslog - try dmesg | tail

any suggestions?

 

Thanks

@johnnie.black That did it, every thing runs now, here is what the system returned:

 

1st command 

Done, had to relocate 1 out of 4 chunks

2nd command

Done, had to relocate 2 out of 4 chunks

now the system reports this for cache drive 1 pool information, the drive shows 1% used on the dashboard.

 

Label: none  uuid: 7c0a6cb7-b610-4a31-9b58-a09704ac0a81
	Total devices 2 FS bytes used 1.17GiB
	devid    1 size 232.89GiB used 3.03GiB path /dev/sdh1
	devid    2 size 232.89GiB used 3.03GiB path /dev/sdg1

is this good? if not what do I do next?

 

Thanks

It looks good, but not sure the call traces were related to the filesystem being almost fully allocated, see if you don't get more now.

 

It's good practice to run a weekly balance to keep it under control until you update to v6.4, now on kernel 4.14 which should fix this issue, and my early testing seems to confirm it does fix it.
