Cannot inrease var filesystem Cannot inrease var filesystem mar3i (Systems Engineer) (OP) 17 Oct 21 09:11 Hi All, When i tried to increase the var filesystem, i get the below error: Appreciate your support Thanks RE: Cannot inrease var filesystem iggsterman (TechnicalUser) 17 Oct 21 20:13 Because you do not have enough room on the volume group. Increase the underlying VG and then try again. RE: Cannot inrease var filesystem pa2nc (Programmer) 16 Nov 21 21:33 As iggsterman responded, you do not have enough available space. Run lsvg rootvg and look for FREE PPs. You will see that you do not have enough to fulfill your request. You need to add another hdisk with extendvg or if you are using SAN storage you can simply increase the existing LUN size followed by chvg -g rootvg (g=grow). Then, you should be able to add space to the /var filesystem.
