Scenario:
df -gt /oracle
Filesystem GB blocks Used Free %Used Mounted on
/dev/oralv 100.00 49 50 50% /oracle
/dev/oraloglv 100.00 49 50 50% / /oralog
shrink /oracle file system by 20 GB and add that space to /oralog filesysetm
solution
:
**make sure that both filesystem are in same volume group,if not then we unable to allocate space
which we shrink from /oracle File system.
then use following command to shrink /oracle
#chfs -a size=-20G /oracle
above command will take some time ....
Then check again size of File system it must be resized to 80 GB.
Then next step is add that 20 GB which we taken from /oracle to /oralog.
command to extend size of /oralog
#chfs -a size=+20G /oralog
new size of /oralog will be 120GB .
