Lage file enabled FS

Guru's

No, its not a questionnaire, but couple of doubts i have :-)

1) How do i check if a FS is Large file enabled or not (from the command line)

2) If the FS is not large file enabled, how do i enable it? can it be done online or do we have to recreate the FS.

3) This question might sound silly, but i have to ask it.
One of my user's is not able to create a file more than 2GB on a NFS. the FS is mounted on a HP box,
My question is should i check on the machine on which the FS is exported if the FS is larger file enabled or not?

Thanks for your time in advance,
Pattabhi Raman

1. mkfs -m -F vxfs /dev/vgxx/lvolxx

or

fsadm -F vxfs /mountpoint

2. Enabling Large files if you have OnlineJFS:

# fsadm -F vxfs -o largefiles /mountpoint

3. Yes. you should check from where this Mount Point is exported. (Server)

Hi Pattabhi,

To check if largefiles are enabled -

fsadm -F vxfs /dev//

If it is then it will respond with largefiles.

If it is not enabled, then you can enable it by using fsadm

fsadm -F vxfs -o largefiles /dev//

If you do not have Online JFS then you will need to umount it and remount it with the options in the fstab set as

rw,largefiles,delaylog

and then mount the filesystem

Your final question, I would check the NFS server for largefiles first.

Mike.

Hi Pattabhi,

1) vi /etc/fstab (must have the largefiles option). If you don't see it, you don't have the largefiles option enabled.

2) You can do it in SAM ou editing by /etc/fstab. But you will need to unmount and mount each logical volume.

3) Yes.

Best Regards,
