Titania,

For changing the largefiles bit in HFS The file system MUST be unmounted.

To convert the HFS file system to largefiles capable:

#fsadm -F hfs -o largefiles /dev/vg#/lvol#

To mount the new largefiles capable file system :

#mount -F hfs -o defaults,largefiles /dev/vg#/lvol# /(mountpoint)

To set the correct /etc/fstab syntax:

/dev/vg#/lvol# /stand hfs defaults,largefiles 0 2

To verify the largefiles being set you can use mount() or fsadm().
Verify with mount() command:

mount -v :
/dev/vg00/lvol1 on /stand type hfs largefiles on Wed Apr 29

I assumed the question was on how to increase the size of the filesystem, not set the largefiles bit?

So for the former the answer is it can't increase the size.

Indead Dennis

Extending an hfs FS is done with

extendfs -F hfs

man extendfs_hfs

titania,

Dennis is right, it is only applicable for vxfs if you want to increase size,

#fsadm -F vxfs -b M /dev/vgXX/lvolXX

-F represents what filetype
-b represents the size
M represents 'Megabytes'

Example:

#fsadm -F vxfs -b 100M /dev/vg03/lvol2
This will extend lvol2 100 megabytes with a vxfs filetype

Hi,

No.

You need to
# umount /filesystem
# lvextend -L new_size /dev/vgxx/lvoly
# extendfs -F hfs /dev/vgxx/rlovy
# mount /filesystem

You can not use fsadm.

you need to do a lvextend on file system you want to extend, then u can use fsadm if Online Jfs is installed,
command syntex for fsadm is
fsadm -F hfs /dev/vg02/rlvol1
man fsadm_hfs
