Squid Posted December 10, 2017 Share Posted December 10, 2017 Its issuing the call trace when unmounting your cache drive. I *think* its because of this: Label: none uuid: 7c0a6cb7-b610-4a31-9b58-a09704ac0a81 Total devices 2 FS bytes used 110.15GiB devid 1 size 232.89GiB used 231.88GiB path /dev/sdj1 devid 2 size 232.89GiB used 232.88GiB path /dev/sdi1 But @johnnie.black is the real expert all things btrfs Quote Link to comment
JorgeB Posted December 10, 2017 Share Posted December 10, 2017 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: Quote Data, RAID1: total=230.85GiB, used=109.81GiBData, single: total=1.00GiB, used=0.00B System, RAID1: total=32.00MiB, used=48.00KiB Metadata, RAID1: total=1.00GiB, used=356.72MiB GlobalReserve, single: total=131.64MiB, used=0.00B Quote Link to comment

DocLove Posted December 11, 2017 Author Share Posted December 11, 2017 @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 The Doc Quote Link to comment

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.

DocLove Posted December 12, 2017 Author Share Posted December 12, 2017 Thank you so much @johnnie.black for your support in working on this problem, do you know when is v6.4 going to be released? the most current stable version is 6.3.5. The Doc Quote Link to comment
JorgeB Posted December 12, 2017 Share Posted December 12, 2017 No idea, you can check the progress on the v6.4 prerelease forum. Quote Link to comment
