/dev/vglog/lvmlogb /oracle/FDN/mirrlogB vxfs rw,suid,nolargefiles,delaylog,datainlog 0 2

Shalom,

After you have used newfs to create a filesystem without largefile support you have two options to fix it.

Convert it with fsadm

newfs -F vxfs -o largefiles

The second option is destructive.

As far as I know 11i v1(11.11) dropped support for the largefiles paramter in /etc/fstab

I doubte 11i v2(11.23) as put that back in.

HI:

If you have Online JFS installed (which I hope you do) you do not need to unmount a filesystem to enable largefiles support.

With Online JFS:

# fsadm -F vxfs -o largefiles /mountpoint

Without Online JFS:

# umount /mountpoint
# fsadm -F vxfs -o largefiles /dev/vgNN/rlvolXX

...note the use of the (r)aw device file above.

Regards!

HI AFA,

Follow these Steps to change the FS.

1. Unmount FS by following commands.

umount /oracle/FDN/mirrlogA
umount /oracle/FDN/mirrlogB
umount /oracle/FDN/origlogA
umount /oracle/FDN/origlogB

2.Use fsadm command to change largefiles.

fsadm -F vxfs -o largefiles /dev/vglog/rlvmloga
fsadm -F vxfs -o largefiles /dev/vglog/rlvmlogb
fsadm -F vxfs -o largefiles /dev/vglog/rlvologa
fsadm -F vxfs -o largefiles /dev/vglog/rlvologb
3.Change entries in /etc/fstab
4.mount -a
