Hello,
I'm using 8 2TB disk in RAID10 for data and meta.
Zo a native usable spavce of 7.3TB is acceptable (logical).
I created 1 volume with all disk and mount them on /btrfs.
2 folders are created:
iscsi = containing iscsi volumes
samba= contiing folders for Samba.
When I do a du -h /btfs I use 4.8TB of disk, but btrfs is telling me the filesystem is full.
btrfs fi sh:
root@sanos1:~# btrfs fi sh

Btrfs v3.18.2

Question:
Where is mu 2.4TB disk space and because btrfs is full, everything is slow now?
Thanks.
