Expand /usr

[Peter Chuang]

my /usr is 100% full

/dev/vg00/lvol6 861557 775402 0 100% /usr

I have the command from previous thread

lvextend -L 500 /dev/vg00/lvol6

what is 500 stand for?

Thanks in advance

500MB size. See lvextend man page. Since your /usr is around 800MB, you'll want a bigger value than 800.

after you extend the lvol you will want to extend the file system. if you have onlinejfs you can

# fsadm -b 800M /var

Hi Peter:

# man lvextend

And take a look at the examples in "man lvextend". By the way, you will most likely need to reboot in single user mode in order to get /usr unmounted.

Hi,

If you look at the man page, you will see that the -L option sets the new size in MegaBytes.

If you have onlineJFS installed you can increase the /usr filesystem on the fly.

# swlist -l product | grep -i online

Then the command would be

# lvextend -L xxxxx /dev/vg00/lvol6
xxxxx = new size of /usr
# fsadm -F vxfs -b xxxxxM /usr

If you do not have OnlineJFS installed, you will have to reboot into single user mode.

# shutdown -r -y now
interrupt boor process
boot pri ipl
ISL> hpux -is
# /sbin/lvextend -L xxxxx /dev/vg00/lvol6
# /sbin/extendfs /dev/vg00/lvol6
# mount /usr
# shutdown -r -y now

Regards,
Robert-Jan
