Info:
Aix 4.3.3
file system is jfs.
(forgive me, I'm a solaris kinda guy)

I forgot to turn on largefiles for a /udb file system. I am wondering
(hoping) that I can edit /etc/filesystems to largefiles, umount/mount,
possibly reboot. If not I can backup/nuke/make/restore with no
issuses, just hoping it won't be that time consuming.

Tried smitty jfs, but unable to change it.

No chance to change the fs.

Make a new fs with large file enabled, mount it, and do a copy from the
old one to the new one. After you can just switch the mount points.

To enable large files, you have to use the flag "-a bf=true" on the
crfs command, it is not possible to do it on the fly or by changing
and rebooting. It depends how much data is in the filesystem ast to
how long it will take to achieve the backup and restore.

That is your *only* option.

BAH! Not the answer I *wanted*, but that's what I expected. Thanks
for responding so quick. Take care all.
