fsadm command

[Silvance Daniel]

I want to enable largefilesize(more than 2GB) of a file system by using 'fsadm' command.

What is the syntax of that command?

Whether that command will affect the the existing data in that file system?

Hi,

Depends if you have or have not have OnlineJFS installed.

# fsadm -o largefiles /app/oracle/dbappl
fsadm: /etc/default/fs is used for determining the file system type
fsadm: /app/oracle/dbappl is not a valid operand

# umount /app/oracle/dbappl
# fsadm -o largefiles /dev/vg01/rlvol4
# mount -a

Regards,
Robert-Jan

Hi,


# umount /
# fsadm -F vxfs -o largefiles /dev/vgXY/rlvolX

man fsadm gives you an example.

If you have onlineJFS - you can do it without unmounting.

fsadm -o largefiles /mountpoint

Otherwise, unmount it,

fsadm -o largefiles /dev/vgXX/lvolXX

make sure you update /etc/fstab:

Example:
/dev/vg00/lvpub /pub vxfs rw,suid,largefiles,delaylog,datainlog 0 2

Unmount the filesytem first.

fsadm -F -o largefiles

And specify /etc/fstab entry with largefiles there.

Examples are provided on fsadm man page.

Note: There are possiblity to get problem during largefiles enablement. < 10.20 ( it can not be mounted )

Refer fsadm_vxfs.1 man page largefile flag part

Hi.
You also can enable this option by using SAM
