Hi Atul

raw file system is that which have no valid file system.
after creating lvol, application used the lvol as raw file system. no need to create mkfs command.

you can extend lvol.

And to extend a raw file system, you are simply extending the lvol using the lvextend command(s).

Rgrds,
Rita

I will make it little bit more clear as mentioned above:

lvcreate -L 100MB -n oravol1 /dev/vgora

[will create 100MB size lvol named oravol1 on vgora volume group.

lvextend -L 200 /dev/vgora/oravol1

[will extend the above LV to 200MB]

When you start to use it (with oracle or any RDBMS) mention it with the prefix of "r" (raw)
i.e., /dev/vgora/roravol1

oravol1 will be called as roravol1.

Regards.
