[arch-general] Btrfs blues - lack of space

[Savyasachee Jha]

Hello, all

The contents of my /etc/fstab are as follows:

/dev/sda3               /             btrfs
rw,relatime,space_cache,autodefrag    0 0
/dev/sda1               /boot         ext2          rw,relatime    0 2
/dev/sda5               /home       btrfs
rw,relatime,space_cache,autodefrag    0 0

Whenever I start my laptop up, /home takes ~17-19 seconds to mount, as is
evidenced by this line in the output of systemd-analyze blame:

16.467s home.mount

Running df -h on my system, I get:

Filesystem       Total    Used   Free   Use%     Mounted on
/dev/sda5         422G   364G   53G   88%        /home

However, running du -h --summarize /home, I get:

318G /home

If I use xdiskusage to see the partition, it shows 46.48G as
/home/(permission denied). I tried doing this using sudo, and I still have
the same problem. I have neither subvolumes nor any snapshots on this
volume.

Is there any way of recovering this space?

Thank you,
Savya
