Steps to extend a filesystem

[Jonathan Grymes]

Please provide steps to extend logical volume and file system from 8GB to 15GB. I do not have online JFS.

The system is HPUX 11.31 rx2660 itanium.

/dev/vg01/gexvar   8388608 8301364   83091   99% /gex/var

Thanks

Jon

Unmount the file system:

# umount /gex/var

If it won't umount because it is busy, then you will have to stop all processes accessing the file system and then umount it.  

To see all processes accessing it:

# fuser -cu /gex/var

Once all processes have been killed / stopped, then umount again:

# umount /gex/var

Once it has been unmounted --

Extend the LV:

# lvextend -L 15360 /dev/vg01/gexvar

Extend the file system:

# extendfs /dev/vg01/rgexvar

Remount it:

# mount /gex/var

Verify new size:

# bdf /gex/var

Restart any applications / processes that use the file system.

There are many ways to extend to do this.

1. unmount the Filesystem and extend .

2. Boot system into single user mode and extend.
