fs with a large file option?

[Gerald_13]

hi,
how to create fs with a large file option ?
(with command line)
thanks for your help.
regard,
Gerald

[Stefan Farrelly · Accepted solution]

fsadm -F vxfs -o largefiles

If you have online jfs you can do this while the filesystem is mounted, if not, you will need to unmount it first, run the command, then mount it again.

Hi!
With "-o largefiles":

1 example:
#mkfs -F vxfs -o largefiles /dev/vg01/rlvol1

2 example:
#mkfs -F hfs -o largefiles /dev/vg01/rlvol1

an existing filesystem you can modify for largefiles:

# fsadm -F vxfs -o largefiles mnt_point

and a new filesystem with largefile option can be created like follows:

# mkfs -F vxfs -o largefiles /dev/vgXY/rlvolX

To get the largefile option you have to mount the filesystem with this option and also add it in the /etc/fstab if necessary:

# mount -F vxfs -o largefile /dev/vgXY/lvolX /mnt_point

[T G Manikandan]

If you are doing that on a vxfs file system.

If you have Online JFS then you can extend without umounting the file system as Stefan suggested.
Else you have to umount the file system to enable large files.

Make sure you update the /etc/fstab after enabling it

Thanks

hello gerald,

if you are using SAM to create the logical volume, under "Modify FS Defaults..." -> "file System Attributes", you have "Allow Large Files" which will have to be checked.

Hope this helps too!
