First find how much space available to extend
[root@xxx-bac02 ~]# vgdisplay -s
"VGExaDb" 3.27 TiB [185.00 GiB used / 3.09 TiB free]
[root@xxx-bac02 ~]# vgdisplay -s
"VGExaDb" 3.27 TiB [185.00 GiB used / 3.09 TiB free]
Here we have 3.09TB free
First check the existing size of /u01
df -kh |grep u01
/dev/mapper/VGExaDb-LVDbOra1 99G 27G 67G 29% /u01
Currently it is 100GB
I want to increase to 150GB
So here are the commands
lvresize -L +50G /dev/mapper/VGExaDb-LVDbOra1
resize2fs /dev/mapper/VGExaDb-LVDbOra1
Now if you recheck the size again
df -kh |grep u01
/dev/mapper/VGExaDb-LVDbOra1 148G 36G 105G 26% /u01
**********************************************
For XFS file system on new exadata machines
determine if it xfs or ext etc
[root@nasipedwdb-bac02 ~]# df -Th |grep /
Filesystem Type Size Used Avail Use% Mounted on
/dev/mapper/VGExaDb-LVDbSys1 xfs 15G 12G 3.3G 79% /
lvresize -L +50G /dev/mapper/VGExaDb-LVDbSys1
xfs_growfs -d /
[root@nasipedwdb-bac02 ~]# df -kh
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VGExaDb-LVDbSys1 65G 12G 54G 19% /
