kde 4: Disk Space widget: curious discrepancy

Hi,

Different utilities show different disk usage:

$ df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/sda2              29G  8.0G   20G  29% /
none                  474M   12K  474M   1% /dev/shm
/dev/sda3             261G  247G  971M 100% /home

Disk Space widget:

Home: 14.2 GiB
Root: 20.9 GiB

df results look more credible

Curiously, Root usage checks, more or less. Could it be something more subtle than a mere Disk Space widget bug?

29G - 8G gives you 20.9GiB for root
261G -247G gives you 14.2 GiB for home

:D

Which indicator is useless, then? df or Disk Space?

Re: kde 4: Disk Space widget: curious discrepancy

Maybe both are working well (you need to know the math and conditions each program uses).
I would go with df though, if I'm not wrong it takes into account the reserved space for root that each partition usually has. Because a normal user can't access it it doesn't count as free space.

Maybe the Disk Space widget doesn't take that into account and gives you different results.

Use "command watch" widget with df, and you're done. Tweak it with awk to get some prettier look if you wish

You mean, in the range of gigabytes? Sounds funny.
