about largefiles

[Rambo_1]

Hi ,
After I made a new Lv_data with file system
#lvcreate -L 10000 -n Lv_data /dev/vg00
#newfs -F vxfs -o largefiles /dev/vg00/rLv_data
#mkdir /Lv_data
How to vi the /etc/fstab ?

Thanks

add something similar too:

/dev/vg00/Lv_data /Lv_data vxfs rw,largefiles,delaylog,datainlog 0 2


thats just one example there are other options you can use also. suid, nosuid etc...

Not sure what you are asking here.

#vi /etc/fstab

#man vi
for how to use vi.

Like Marvin already mentionned the largefiles option will have to be included in the option portion in your /etc/fstab. Several options are available to you along with largefiles. You can read the man for mount_vxfs for all the different options..


your /etc/fstab will look similar to this :

/dev/vg/lv /mountpoint vxfs largefiles,delaylog 0 2

if I am not wrong, mount automatically enables the largefiles based on the largefiles compatibility bit in the FS meta data. So even if you leave the defaults, it should not hurt.

mv /etc/fstab /etc/fstab.orig
mount -p > /etc/fstab

Can I add something similar below??

/dev/vg00/Lv_data /Lv_data vxfs delaylog 0 2

there are no largefiles,rw,detainlog options.

thank you

As a final check you can employ the following command to verify the options
employed while creating your filesystem:

mkfs -m /dev/vgXX/lvolXX

where XX refers to the volume group and lvol id corressponding to your new filesystem.
