How to chage nolargefiles to largefiles in /dev/vg00/jefftest, I was using the below command but get the error message?
Notes: no online JFS,

fsadm -F vxfs -o largefiles /dev/vg00/jefftest
vxfs fsadm: /dev/vg00/jefftest is not the root inode of a vxfs file sytem

Try unmounting the filesystem.

I'ved check the man and the command is properly formatted.

Make sure you have the logical volume name right. Prior to umount bdf and make sure its right.

Thanks, how to verity the /jefftest is largefiles supported?

Hi,
when you change the filesystem to "largefiles" you also need to add largefiles as mount option for the filesystem in question in /etc/fstab. If not, you will get a mount error when trying to mount the file system again.
Unfortunately, I have forgotten what the error message looks like, but the idea is that the mount options must match the actual setting of the file system.

regards,

Hi,

# fsadm -F vxfs /dev/vg01/rlvol4
nomultifsets
largefiles

run fsadm with no options.

Do you mean the fsadm works now?
Because if I look at the error message, you have a version of fsadm that needs the mountpoint as argument, not the device file (this is the case for vxfs filesystems, while hfs needs the device files).
For vxfs filesystems you don't have to change anything in /etc/fstab.
For hfs it is indeed needed and you should be able to set it runtime by using:
mount -o remount,largefiles

Just check

swlist |grep -i onlinejfs

If that is not there then you cannot do things online

you have to umount and then mount after converting it to largefiles

ALso make sure that you update /etc/fstab.

to check for largefiles already enabled

fsadm -F vxfs /dev/vg00/rlvol?
