Re: Create a large filesystem after creating filesystem

Hi,

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

and don't forget to update the /etc/fstab

Re: Create a large filesystem after creating filesystem

you can use sam also and check the largefiles box for large files support.

Re: Create a large filesystem after creating filesystem

Hi,

You can use fsadm as suggested by Robert or if you do not have any data on the filesystem as yet , you can recreate the filesystem , this time give the
-o largefiles
option with the mkfs/newfs command. and modify /etc/fstab entry to update the largefiles option.

Re: Create a large filesystem after creating filesystem

Hi Dhamodharan,

With Online-JFS

#/usr/sbin/fsadm -F vxfs /file_system_path
If the output shows largefiles, then large files are activated.If it shows nolargefiles large files are inactive.

To change a file system to support large files, do following:

# /usr/sbin/fsadm -F file_system -o largefiles /dev/vgxx/lvolx

for example
# /usr/sbin/fsadm -F vxfs -o largefiles /dev/vg01/lvol6
