My /etc/mnttab file is showing ro permission for /usr

Hi All,

My current /usr utilization is 100%.As i don't have another harddisk i decided to delete some unnecessary files under /usr.But,while deleteing it is giving error "it is a readonly filesystem".I checked /etc/mnttab file it is showing the following entry

Code:
/dev/lofi/1     /usr    hsfs   ro,noglobal,maplcase,rr,traildot,dev=2400001    1298120730

As far as i understand it is mounted as "readonly" .

As far as i know i cannot modify /etc/mnttab file.Please suggest what changes i should do i am able to delete files under /usr or entry becomes "rw".

Urgent help would be appreciable.

Regards
