Unfortunately this didn’t seem to correct the problem. Please see below:

devid 2 size 465.76GiB used 247.01GiB path /dev/sdb
rockstor mounts everything over and over, even if I manually unmount, so I did
the following:
> umount /mnt2/pool_homes; mount -o clear_cache /dev/sda /mnt2/pool_home
dmesg shows the following:
[ 3473.848389] BTRFS info (device sda): use no compression
[ 3473.848393] BTRFS info (device sda): disk space caching is enabled
[ 3473.848394] BTRFS info (device sda): has skinny extents
[ 3548.337574] BTRFS info (device sda): force clearing of disk cache
[ 3548.337578] BTRFS info (device sda): disk space caching is enabled
[ 3548.337580] BTRFS info (device sda): has skinny extents
Any help is appreciated!
