discrepency between bdf and df -x

Jürgen Heim — Thu, 18 May 2006 10:15:31 GMT

Hi!

How can I find the process that still blocks space in the filesystem? If I do a bdf I get following output:
/dev/vg00/lvol3 512000 497320 14680 97% /
and if I use the df -x command it reports:
root@hpus0301:(/)#du -xks
101408 .
I.e. according to bdf in the root fs 497MB is used, according to du only 101MB!

Thanks!

df reports the total size minus the 'minfree %'

bdf reports the total size

Use lsof to list open files and understand which process is causing the / to be full and kill the process.

Hi JÃ¼rgen,

Try using lsof or fuser on /dev/vg00/lvol3.

The discrepancy between bdf and du is usually caused by processes holding open files that have been deleted. Use lsof to find out which those files are:

# lsof +aL1 /
