large file systems

[Shankar_6]

Hi all,

I wanted to set the larg file option for an existing file system.
after firing the fsadm command it gave the following error,

fsadm -F vxfs -O largefilesystem /dev/vg01/lvol1

vxfs fsadm: /dev/vgo1/lvol1 is not the root inode of a vxfs file sytem

Thanks,

The command needs to be as follows.

fsadm -F vxfs -o largefiles /dev/vg01/lvol1
If you do not have onlineJFS, you need to unmount the FS, If you have it, then
fsadm -F vxfs -o largefiles /mount_point will do it.

Hardcore the settings in /etc/fstab.

You got two things wrong (assuming this is a vxfs filesystem)

fsadm -F vxfs -o largefiles /dev/vg01/lvol1

I would try the command as follows:
fsadm -F vxfs -o largefiles /dev/vg01/lvol1

If you have OnlineJFS you can do:

fsadm -F vxfs -o largefiles /mountpointname

If /dev/vg01/lvol1 is mounted as /spot then

fsadm -F vxfs -o largefiles /spot

when i check using fstyp its showing me as Vxfs....how to conclude whether its JFS or online JFS...online JFS has been installed in the system..

You should use mount point instead of device name.

Hi Shankar,

I assume that you dont have an online JFS and since do

# fsadm -F vxfs -o largefiles /mount_point

Hi,

do

#swlist | grep -i jfs

and will give the following output if Online JFS is installed.
