switch from nolargefiles to largefiles

[Roberto Martinez_6]

Hi,
Is there a way to alter a filesystem created with "nolargefiles" so it becomes "largefiles" aware? (without erasing contents or re-creating the fs)?

TIA

[Vicente Sanchez_3]

Hi Roberto,

fsadm -o largefiles /dev/vgxx/lvolxx

Regards, Vicente.

Roberto:

I think, there's no other way than re-creating a
filesystem that handles large files. (HP-UX 11.00)

[T G Manikandan · Accepted solution]

#usr/sbin/fsadm -F vxfs -o largefiles /dev/vgxx/rlvolx

use the character device--rvol

then mount the filesystem
#/usr/sbin/mount -F vxfs -o largefiles /xxx



Also make sure that you update the /etc/fstab


Thanks

Thank you! It is always good, writing "I think ..." than saying something for sure ...

use fsadm. man fsadm for more details.

Hi,
with this config:

/dev/vgb2/lvol3 /mountdir vxfs rw,suid,nolargefiles,delaylog,datainlog 0 2

, fsadm -o largefiles /dev/vgb2/lvol3 yields:
vxfs fsadm: /dev/vgb2/lvol3 is not the root inode of a vxfs file system.

?!?!

I've tried with the rlvol device, it works silently but when trying to mount, got:
vxfs mount: mount option(s) incompatible with file system /dev/vgb2/lvol3
...

Hi,

If your 'fsadm' command worked with no complaints using the rlvol3 device, then it was successful. You'll just need to modify your /etc/fstab entry so that it says 'largefiles'.

Exact. thanx all.

[Robert-Jan Goossens]

Hi,

Use
# /usr/sbin/fsadm -F vxfs -o largefiles /filesystem_name

or

# umount /filesystem
#/usr/sbin/fsadm -F vxfs -o largefiles /dev/vg00/rlvol9
# mount /filesystem

Hope it helps,

Robert-Jan.

Do you have Online JFS installed on the server.

#swlist -l |grep -i onlinejfs
If not then you will need to
umount the file system and then

run fsadm against the raw volume and then mount it.
