Steps to extend a filesystem

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

Re: Steps to extend a filesystem

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.

Re: Steps to extend a filesystem

There are many ways to extend to do this.

 

1. unmount the Filesystem and extend .

2. Boot system into single user mode and extend.
