UNIX for Dummies Questions & Answers

Hi All,

The root file system of the HP-UX serevr I use is showing as 100% full.

It has a disk space of ~524MB. When I add up the sizes of all the files and directories (using du -sk) , except mount points, it came up to 237MB.
But when I bdf it still shows 100% full

Can anyone help please

Thank You

can you please post bdf and du -sk o/p. may be there is something you are missing.

The issue could be because a file to which a process was writing got deleted, but the process is till running. Since there is no entry in the directory the

Code:

du -sk

doesnt show that the filesystem is full, but the bdf shows the output. Since a process is still referencing the inode to write to the file, the filesystem gets full eventhough the file to which the process was writing got deleted.

Try using lsof/fuser to find out the process still writing to the filesystems and then kill the process.

Code:

lsof mount_point
fuser -d mount_point
