modidy vxfs attribute

Hi, ALl master,

I have a vxfs created before. Now I want to create a file larger than 2G on it. But this vxfs was created with 'nolargefiles' option. I have some data on this file system, so I wonder if I can modify this vxfs with 'largefile' enabled without recreating this filesystem. Thanks.
Keep finding is the way.

Re: modidy vxfs attribute

Yes, you can do this without re-creating the LV.

You can do:

# fsadm -o largefiles /mount_point

I think you should be able to do this without unmounting the LV.

Re: modidy vxfs attribute

to check if largefiles are enabled:

/usr/lib/fs/vxfs/fsadm /mountpoint
nolargefiles

you can change this on the fly with fsadm like this:

/usr/lib/fs/vxfs/fsadm -o largefiles /mountpoint

You can only do this on-the-fly if you got AdvanceJFS.

# /usr/sbin/fsadm -F vxfs -o largefiles /mount
