OCI - How To Add Virtual Memory Partition in Oracle Linux 8 or 9 Platform Images
Applies to:
Oracle Cloud Infrastructure
Linux x86-64
Goal:
Add additional virtual memory (aka swapfile) as an additional partition to an Instance running the OCI Oracle Linux 8 or 9 Platform Image.
Solution:
When an Instance is created from an Oracle Linux 8 OCI Platform Image, the below can be observed:
[opc@instance ~]$ ls -ilha /.swapfile 13014 -rw-------. 1 root root 4.0G Apr 25 09:16 /.swapfile [opc@instance ~]$ cat /etc/fstab | sed 's/#.*$//g;/^ *$/d' /dev/mapper/ocivolume-root / xfs defaults 0 0 UUID=f7cf63bd-4975-44bb-ba99-b81e037be7e1 /boot xfs defaults 0 0 UUID=9814-8B9E /boot/efi vfat defaults,uid=0,gid=0,umask=077,shortname=winnt 0 2 /dev/mapper/ocivolume-oled /var/oled xfs defaults 0 0 tmpfs /dev/shm tmpfs defaults,nodev,nosuid,noexec 0 0 /.swapfile none swap sw,comment=cloudconfig 0 0 [opc@instance ~]$ lsblk -flamp NAME FSTYPE LABEL UUID MOUNTPOINT SIZE OWNER GROUP MODE /dev/sda 46.6G root disk brw-rw---- /dev/sda1 vfat 9814-8B9E /boot/efi 100M root disk brw-rw---- /dev/sda2 xfs f7cf63bd-4975-44bb-ba99-b81e037be7e1 /boot 1G root disk brw-rw---- /dev/sda3 LVM2_member tixqPz-Ls6v-ejHE-mL8K-Zavk-d0hl-C5O4xj 45.5G root disk brw-rw---- /dev/mapper/ocivolume-root xfs 8b8d3b19-9faa-4dee-b3ba-765c3515b283 / 35.5G root disk brw-rw---- /dev/mapper/ocivolume-oled xfs 21d53c77-7876-4a1c-b4e1-a8cd74d1938c /var/oled 10G root disk brw-rw---- [opc@instance
