On my AIX 6.1 server, i have a problem on a VIO LPAR.
A filesystem seams to be full with the 'df' command, but not with 'du' or 'ls' for example.
I searched but I don't understand where the problem comes from.
The 'df' command shows :
[root@VIO2] /var/vio/storagepools/VIO2_storfs_rvg #df -IMvm | grep var
/dev/hd9var /var 1024.00 497.91 526.09 49% 9226 122167 8%

The 'du' command :
[root@VIO2] /var/vio/storagepools/VIO2_storfs_rvg #du -sx *

And some 'fuser' commands :
[root@VIO2] /var/vio/storagepools/VIO2_storfs_rvg #fuser -dV /var/vio/storagepools/VIO2_storfs_rvg
/var/vio/storagepools/VIO2_storfs_rvg:
[root@VIO2] /var/vio/storagepools/VIO2_storfs_rvg #fuser -dV /var
/var:
Thanks in advance if anyone can explain!

The
df
program reports the amount of space available to a non-root user no matter who runs it. This has been historically true, and I imagine it remains so. The rational is that if a regular program fills a partition, root has a little extra workspace to correct the problem. This was especially true if the offending process was still trying to consume all available space.I don't have access to an AIX machine, but you might look in
sys/mount.h
, if it's around.
