enabling largefiles option for a file system while it is till mounted

[zhi wang_1]

Forgot to run newfs -F vxfs -o largefiles /dev/vgxx/lvol1 while creating the file system. It has online-jfs, wonder if I will be able to modify the configuration without "umounting" the file system. In other words, will I be able to make the file system accept largefiles without taking down the file system? Thx.

Yes:

fsadm -F vxfs -o largefiles /mountpoint

Then update /etc/fstab file as well.

fsadm -o largefiles /

[Mel Burslan]

fsadm -F vxf -o largefiles filesystem_here

(make sure using filesystem not the logical volume)

also

vi /etc/fstab

/dev/vg01/lvol3 /oracle vxfs largefiles,delaylog 0 2

add the largefiles switch

Hi,

#fsadm -F vxfs -o largefiles /mount_point

shall do this.

An entry in /etc/fstab will enable it everytime in future when it gets mounted.

HI,

fsadm -F vxfs -o largefiles mountpoint

is the command to get this done .

largefiles option must be added to the line which mounts the said filesystem in the /etc/fstab file.

thanks

Hi zhi

Yes, with online JFS you can achieve so. Use following cammand

#fsadm -F vxfs -o largefiles mountpoint

and then update /etc/fstab file to reflect the file system with large file option

Zhi,
When you have onlinejfs then;
fsadm -F vxfs -o largefiles mountpoint
and also check&update your /etc/fstab
like;
.....vxfs rw,suid,largefiles,delaylog,datainlog 0 2

Good Luck,
