Need to increase /dev/vg00/lvol3 space



I am pretty new to Unix administration. 

One of my machine shows "/" as 100% used. Below is the bdf output

Filesystem kbytes used avail %used Mounted on
/dev/vg00/lvol3 24510464 24510464 0 100% /
/dev/vg00/lvol1 1835008 198120 1624184 11% /stand
/dev/vg00/etest 5242880 274452 4658008 6% /opt/etest
/dev/vg00/arep 5242880 18941 4897520 0% /opt/etest/repository_archive
/dev/vg00/rep 5242880 696749 4262101 14% /opt/etest/repository
/dev/vg00/atropos 5242880 473504 4472528 10% /opt/atropos
/dev/vg00/lvol4 114688 5496 108344 5% /home


I tried extending the space by using lvextend

# lvextend -L 50000 /dev/vg00/lvol3
lvextend: Not enough free physical extents available.
Logical volume "/dev/vg00/lvol3" could not be extended.
Failure possibly caused by contiguous allocation policy.
Failure possibly caused by strict allocation policy


I need help in understanding this and let me know how we can resolve this.

Re: Need to increase /dev/vg00/lvol3 space

There are 1000 and 1 threads about the same topic.

lvol3 must be contiguous, so you cannot increase it on the fly. Consider to use ignite backup and increase while restoring.

But usually the admin created a new directory directly in root that consumes the space. You should simply not do this!

Hope this helps!
