I play with OVM this weekend and when I try to install Oracle database, it complains that I need increase swap space.
There is a 2 way to increase swap: by adding swap file or add a new swap partition.
Since there is not enough disk space for linux virtual disk in this Oracle virtual machine, so I decide to add new virtual disk as new swap partition.
Here is the step by step
1. Login oracle vm server manager console
2. Select virtual machine name and hit Configuration
3. Hit Storage tab
4. Hit Create New Virtual Disk, for example the new virtual disk is /dev/sdd
5. After virtual Disk created properly, login virtual machine
6. use su to change root user
[soa@vrremcc12c ~]$ su
Password:
7. free -k to check how much swap space is currently used
[root@vrremcc12c soa]# free -k
total used free shared buffers cached
Mem: 6117676 192628 5925048 0 9368 56500
-/+ buffers/cache: 126760 5990916
Swap: 1052248 0 1052248
8. user fdisk -l to check the new partition mounted
Disk /dev/sdd: 5368 MB, 5368709120 bytes
166 heads, 62 sectors/track, 1018 cylinders
Units = cylinders of 10292 * 512 = 5269504 bytes
Disk /dev/sdd doesn't contain a valid partition table
9 format the new partition by fdisk
[root@vrremcc12c soa]# /sbin/fdisk /dev/sdd
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel. Changes will remain in memory only,
until you decide to write them. After that, of course, the previous
content won't be recoverable.

10. setup newly created partition by mkswap
[root@vrremcc12c soa]# /sbin/swapon -s
Filename Type Size Used Priority
/dev/hda3 partition 1052248 0 -1
[root@vrremcc12c soa]# /sbin/mkswap /dev/sdd1
Setting up swapspace version 1, size = 5364318 kB
11. enable swap partition
[root@vrremcc12c soa]# /sbin/swapon /dev/sdd1
[root@vrremcc12c soa]# swap/sbin/on -s
Filename Type Size Used Priority
/dev/hda3 partition 1052248 0 -1
/dev/sdd1 partition 5238588 0 -2
[root@vrremcc12c soa]#
12. update /etc/fstab file with new swap area
/dev/sdd1 swap swap defaults 0 0
