What is the tool used to increase the file system size during online?

[Javier Juarez]

Those are terms usen when you have configred automunter, it means that you use NFS and its configerd to work whith options, hardmount means always try to mount the filesystem, softmount means if can't mount, truy again n times, it is posible via maps, direct indirect or specials.

A direct maps, contains mount information for any numer of unrelated mount points, there is no common mount directory
An indirect map use a common mount directory to make several mount points appear as a common directory
A Special map is predefined and lead to a default mount action.

- soft softmount refer an option that automounter will time out and quit, instead of continuosly trying to contact the missing node (hardmount)

For increase the size of a filesystem online you must have Advanced OnLine JFS installed on your system and the filesystem need be vxfs type . first extend the logical volume

# lvextend -L new_size lvol_name

Then use fsadm command

# fsadm -F xvfs -b new_size_kb /mount_point

The value of new_size_kb is given in data blocks (kilobytes), eg, for a size of 200MB, (200*1024)

# bdf ------- to check new size
