And when we check
# du -k /appl

while
# bdf | grep /appl

Hi Yogi,

Although the "du" command shows that the space is already free, some process still has lock over the blocks.

Use "lsof" to determine the process and kill it.

Hi,
try to reboot your system, sometime LVM doesn't know that you had canecelled a file, especially when the file system is on 100%.
If you cannot reboot, try the fsync and sync commands (they are not dangerous),

This can happen if there is too many open files of big size. Use fuser -cu to find out the pid of application accessing this file system, then use glance to identify if there is any open files related to these PID.

glance -> Select Process (give PID) -> Open Files.

Hope this helps
