Large Files

Peter Reuschlein — Tue, 02 Mar 2004 02:48:23 GMT

Hey Everybody,

i have a little problem using Files larger then 2Gigabyte. We use a vxfs File System and there was the option "nolargefiles" in the fstab. I deleted that option and remounted that volume.
Still there is a max file size of 2 gigabyte.

Any1 knows how to fix that without restarting the server?

Would be pleased about an answer

Hi,

you could add "largefiles" to your fstab :)

and/or use "fsadm -F vxfs -o largefiles ..."

good luck,
Thierry.

If you can umount the filesystem you can make the changes without rebooting your server. If you have online JFS you can do this without even unmounting the FS

# umount /myfs
# fsadm -F vxfs -o largefiles /dev/myvg/mylvol
Change the entry in /etc/fstab to resemble largefiles option
# mount -a

To check to see if you have online JFS
# swlist -l product | grep -i online
If it reports nothing you don't have it.

Hi,

just by editing fstab wouldn't work.

have backup of the filesyetm you wanted to convert into largefiles.
#fstyp /dev/vgxx/lvolxx
(will show you type of file system)
#fsadm -F vxfs -o largefiles /dev/vgxx/rlvolxx
will convert lvolxx in to largefile system.

Hi Peter,

How about doing it online.

# fsadm -F vxfs -o largefiles /mountpoint
# mount -o remount,largefiles /mountpoint

and last but not least alter the fstab.

HTH,

Gideon

Hey every1 thx for the quick answers

vxfs fsadm: /dev/vg01/lvol17 is not the root inode of a vxfs file sytem

thats the error when i try to do that fsadmin thingy on the volume.

here the output of mount -v <-- perhaps that helps

hprp7410:/etc(root)$mount -v

Hi Peter,

So you do not have online jvs,

You will have to umount the filesystem and enable the largefiles option.

# umount /xmlfiles
# fsadm -F vxfs -o largefiles /dev/vg01/rvol17
# mount /xmlfiles

Regards,
Robert-Jan

forgot to add check the output from fsadm after you enable largefiles,

# fsadm -F vxfs /xmlfiles
nomultifsets
largefiles
