strange bdf value

Jerome Salyers — Tue, 02 Apr 2002 08:03:47 GMT

hi...

i'm working on a hpux 11 system (B2000) and have got my /tmp configured at 100MB... at the moment, when i run a du -s -k * in /tmp, i come up with 503KB being used... there are no links anywhere in the dir. or any subdirs... however, my bdf tells me i'm using 98% of my /tmp dir. and i've only got 1.6MB left...

before i reboot, i was wondering if there was anything i've overlooked...

thanks

jerome

There could be some process using up some disk space. use fuser -u to find out who.

Hi Jerome,

It could be file swap taking up your /tmp space or the minfree parameter for that file system too high.
But these are longshots. I think the most probable cause is a file that has been removed but is still being used by a process (so the previus answer is good to find it).
It's a strange behaviour, but even if you remove a certain file, it's blocks won't get cleaned up while there's a process reading/writing to it (that is, with a file handle open to that file).
So, if there's a process writing to /tmp that you can, let's say, kill, the you're Ok. Otherwise, you'll have to reboot sooner or later, since the OS really really needs /tmp.
