fsadm to set largefiles flag

[Thomas J. Harrold]

I remember being able to set the "largefiles" flag on a vxfs filesystem *online* without having to have OnlineJFS installed on my system.

This fails with an error. I can't find any specific comments in the man pages for fsadm that say that the filesystem must be unmounted.

Thoughts?

Hi Thomas:

Specify the *raw* device as the special file argument. Note the "rlvol":

# umount /
# fsadm -F vxfs -o largefiles /dev/vgXY/rlvolX

Then, change the "nolargefiles" to "largefiles" in the appropriate entry in /etc/fstab and remount the filesystem.

I think you misremember; must be unmounted and clean in order to run fsadm w/o online JFS.

Backup file system and:
#newfs -F vxfs -o largefiles /dev/vgxx/lvolxx
