can we change to 'largefiles' option online

[VINU]

Hello friends,


Do we need to reinitialze the file system for chnaging the 'nolargefiles' option to 'largefiles' or just by enabling the 'largefiles' option thru SAM and remount will do.

I don't have the hp online jfs

thanks* regds

Hi Vinu,

Sorry not possible, you will need to umount your filesystem before you can change the largefiles option.

# umount /XXX
# fsadm -o largefiles /dev/vg00/rvolX
change the /etc/fstab
# mount /XXX

Kind regards,

Robert-Jan

If you don't have onlineJFS then you can't do it online sorry.

Furthermore you need to re-create the filesystem (could be wrong on this last part)

Withour online JFS, you can not do that online. You will have to unmount the filesystem do fsadm -F vxfs -o largefiles /dev/vgxx/rlvolxx and mount it again.

Put largefiles option in /etc/fstab for that mount point.

hi vinu

I had tested the following manner - I hope this will suite for u.
*) take full backup
*) unmount ur file system (umount)
*) create file systems with -o largefiles (newfs/mkfs)
*) fsck for the FS
*) mount (mount)

sure
