Hi All,

Good Morning!

I wanted to increase the partion size of /var from the current 10 GB to 15 GB, tried all the ways but not able to. Can someone please help?

Through various help, I have already increased the size of /dev/vg00/lvol2 from 10 GB to 13 GB, lvdisplay showing the same but df -h still showing 10 GB only.

Here are the current details for reference -

Since you've expanded the LV, you just need to "resize2fs" or "ext2online" (depending on your RHEL version) /var. The filesystem doesn't yet know that the underlying device (the LV) is bigger.

This would work if you have a ext3 file system on /var:
