Lost a lot of disk space right after reboot
Hi,
I have a very strange problem. Before rebooting it, I have
root@readynas# df -h
Filesystem Size Used Avail Use% Mounted on
...
/dev/md127 28T 16T 12T 59% /data
/dev/m...
I see no snapshots.
status.log shows the volume usage warning alerts.
I do see a lot of metadata on the data volume and the space on the data volume is fully allocated.
Did you run any scheduled/unscheduled volume maintenance?
Have you checked how much space is consumed by different shares, and also Time Machine (if you use that).
Also have you checked if a user been putting a lot of data into a home share? You can login to SMB as the admin user and check the space consumed by home shares.
Or using SSH you could do e.g.
# du -csh /data/*
to get a rough idea as to what's consuming the data.
du is not designed for BTRFS, so it'll just give a very rough idea.
Is your backup up to date?
