how to make root filesystem support large file.

[Li Chunbo]

In my layout of the filesystem, root filesystem used up all the available disk space, no /usr and /var filesystem. when install the os, I don't notice the large file support option. now how to make root filesystem support large file?
because when I excute command make_net_recovery.
the archieve file is beyond 2gb.

Hi,

To check if it is turned on:
mkfs -F vxfs -m /dev/vg00/lvol

to turn it on:
fsadm -F vxfs -o largefiles /dev/vg00/lvol

( -F vxfs/hfs depending on filesystem used)

Regards,

Hi,

# fsadm -F -o largefiles /dev//

Hi,

check if you have OnLineJFS:

# swlist -l product | grep -i online

If you have it

# fsadm -o largefile /

and change /etc/fstab on / filesystem adding largefile option.

Otherwise go in single user mode with / filesystem unmounted and change /etc/fstab with largefiles option on / filesystem then boot up.

It is needed to go in single user mode because / filesystem should not be unmounted in multi user mode (run-level 3).

HTH.

Best regards,
Ettore

Hi,

#fsadm /dev/vg00/rlvol3

shows whether largefile enables or not

to enable

#fsadm -F hfs -o largefiles /dev/vg00/lvol3.

but it may corrupt the data inside that file system if you enabled largefile option.

Hi,

#fsadm -F vxfs -o largefiles /dev/vgnn/[r]filesystem

To know version and other activated options:
#fstyp -v /dev/vgnn/filesystem

f_flag: 16 indicates you that support large files!

Rgds.
