    • Oracle Linux – How to Change /var Partition to a New Disk

    in Linux 2 comments

    Applies To:

    Linux OS – Version Oracle Linux 7.0 to Oracle Linux 9.0 [Release OL7 to OL9]

    Linux x86_64 on Oracle Public Cloud

    Goal:

    Move /var partition to a new disk to avoid running out of space due big logs from 3rd=party software.

    Symptoms:

    [root@<HOSTNAME> ~]# df -hP | grep root 
/dev/mapper/ocivolume-root   36G   35G  1.2G  97% /

    There was a 3rd-party software with more than 18GiB of logs inside /var (not shown here).

    Solution:

    Before following these steps make sure there is a full and working backup in case anything goes wrong.

    • Create a new Block Volume of at least 50GiB.
    • Attach this Block Volume to the instance selecting "Paravirtualized". DO NOT select ISCSI as this won't work.
