/tmp device busy..

[Jayraj]

Hi,

when I am tried to umount the /tmp directory.. It is giving device busy..I have used
fuser -ku /tmp

stil the error persists..then I rebooted the server.. even it is giving device busy when tried to umount the /tmp..

is there any way to solve this problem

Why do you want to unmount /tmp? /tmp will ALWAYS be in use. 'fuser -ku /tmp' can be dangerous as it may kill some OS processes.

The only way to guarantee that /tmp will NOT be in use is to reboot your system and come up in SINGLE-USER MODE.

When in single-user mode /tmp will NOT be automatically mounted. Nor will any other file systems for that matter.

As soon at that OS is booted, /tmp is used. You don't want to use that fuser -k.
What are you trying to do? You may have to be in single user mode.

Hi , for what reason you like to umount /tmp ??
If it is for increasing the FS then you could only do that via single user mode.

As said above, you cannot umount /tmp FS in multiuser mode

Infact I want to increase the file system space.. since I dont Hace online JFS, I want umount it to apply the lvextend changes..so can we use extend fs in single user mode..

Swaraj,

In that case you have to take your system into single user mode.
