Reduce a File System

Arun Jain — Thu, 28 Feb 2008 09:13:16 GMT

Dear All,

Please let me know if there is any method to reduce the size of a file system.
I can reduce the size of the LV by lvreduce command. But like extendfs is used to extend a fs, any command is there to reduce it.

Regards:
Arun

Hi

try

# fsadm -b

You should reduce the filesystem size first and reduce the lvol second..

Thanks & Regards

Ramesh

fsadm -F -b

if ur giving filesystem size in mega bytes dont forget to postfix "m" with size
lvdisplay will give the filesystem size in mega bytes

eg: to extend a 1GB files to 2 GB

fsadm -F vxfs -b 20480 /siju
or
fsadm -F vxfs -b 2048m /siju
