file systems

[Mark Mitchell]

I wanted to throw this out there. Is there a way to reduce a file system. or do you have to always go in and rebuild it. Since this is posible on the lv level (lvreduce) and so on, i was curious about this....

If you have a advanced jfs (aka online jfs) then you can.
Otherwise, it involved a backup/lvreduce/newfs/restore sequence.

So what are the jfs steps?

[Andy Monks · Accepted solution]

fsadm -F vxfs -b

lvreduce ....

do a man on vxfs_fsadm to ensure you get it correct!.
