(Did you know yesterday came from the word 'yeast'? So actually yeasterday: because one used the yeast of the day before to bake the bread of today. Also in Dutch the word for yeast: 'gist', still sounds in the word for yeasterday: 'gisteren'.)
I ran however against the prerequisite check on the swap space that was only 2GB because of my default OL7 install. And the Universal Installer required 8GB at least. So I needed to expand it. There are several ways to do it. But since I was into SSM, it was a good practice to use that. And it turns out very simple to do. It shows how easy it is to add a new device to a pool and an existing volume.
So I created a new disk of 8GB to my VM (I only need 8GB, but I thought I'd simply add it to the existing 2GB, to be certain to have enough with 10GB).
So, after booting up, verify existence of non assigned device (/dev/sdc):
[root@darlin-vce-db ~]# ssm list
--------------------------------------------------------------

--------------------------------------------------------------
/dev/sda 20.00 GB PARTITIONED
/dev/sda1 500.00 MB /boot
/dev/sda2 40.00 MB 19.47 GB 19.51 GB ol
/dev/sdb 0.00 KB 100.00 GB 100.00 GB pool01

---------------------------------------------------------------------------
/dev/ol/root

/dev/ol/swap
ol 2.00 GB linear
/dev/pool01/disk01
pool01 100.00 GB xfs 99.95 GB 99.95 GB linear /u01
/dev/sda1
500.00 MB xfs 496.67 MB 305.97 MB part /boot
---------------------------------------------------------------------------
Then add the device to the 'ol'-pool:
[root@darlin-vce-db ~]# ssm add -p ol /dev/sdc Physical volume "/dev/sdc" successfully created Volume group "ol" successfully extended
And verify again:
[root@darlin-vce-db ~]# ssm list -------------------------------------------------------------- Device Free Used Total Pool Mount point -------------------------------------------------------------- /dev/sda 20.00 GB PARTITIONED /dev/sda1 500.00 MB /boot /dev/sda2 40.00 MB 19.47 GB 19.51 GB ol /dev/sdb 0.00 KB 100.00 GB 100.00 GB pool01 /dev/sdc 8.00 GB 0.00 KB 8.00 GB ol -------------------------------------------------------------- ---------------------------------------------------- Pool Type Devices Free Used Total ---------------------------------------------------- ol lvm 2 8.04 GB 19.47 GB 27.50 GB pool01 lvm 1 0.00 KB 100.00 GB 100.00 GB ---------------------------------------------------- --------------------------------------------------------------------------------------- Volume Pool Volume size FS FS size Free Type Mount point --------------------------------------------------------------------------------------- /dev/ol/root ol 17.47 GB xfs 17.46 GB 12.29 GB linear / /dev/ol/swap ol 2.00 GB linear /dev/pool01/disk01 pool01 100.00 GB xfs 99.95 GB 99.95 GB linear /u01 /dev/sda1 500.00 MB xfs 496.67 MB 305.97 MB part /boot ---------------------------------------------------------------------------------------
Now resize the swap volume:
[root@darlin-vce-db ~]# ssm resize -s+8GB /dev/ol/swap Size of logical volume ol/swap changed from 2.00 GiB (512 extents) to 10.00 GiB (2560 extents). Logical volume swap successfully resized
And, again, verify:
[root@darlin-vce-db ~]# ssm list -------------------------------------------------------------- Device Free Used Total Pool Mount point -------------------------------------------------------------- /dev/sda 20.00 GB PARTITIONED /dev/sda1 500.00 MB /boot /dev/sda2 0.00 KB 19.51 GB 19.51 GB ol /dev/sdb 0.00 KB 100.00 GB 100.00 GB pool01 /dev/sdc 36.00 MB 7.96 GB 8.00 GB ol -------------------------------------------------------------- ----------------------------------------------------- Pool Type Devices Free Used Total ----------------------------------------------------- ol lvm 2 36.00 MB 27.47 GB 27.50 GB pool01 lvm 1 0.00 KB 100.00 GB 100.00 GB ----------------------------------------------------- --------------------------------------------------------------------------------------- Volume Pool Volume size FS FS size Free Type Mount point --------------------------------------------------------------------------------------- /dev/ol/root ol 17.47 GB xfs 17.46 GB 12.29 GB linear / /dev/ol/swap ol 10.00 GB linear /dev/pool01/disk01 pool01 100.00 GB xfs 99.95 GB 99.95 GB linear /u01 /dev/sda1 500.00 MB xfs 496.67 MB 305.97 MB part /boot ---------------------------------------------------------------------------------------
Now check the swap space:
[root@darlin-vce-db ~]# swapon -s Filename Type Size Used Priority /dev/dm-1 partition 2097148 0 -1
Hey, it's still 2GB!
Let's check fstab to get the swap mount-definitions:
[root@darlin-vce-db ~]# cat /etc/fstab # # /etc/fstab # Created by anaconda on Mon May 11 20:20:14 2015 # # Accessible filesystems, by reference, are maintained under '/dev/disk' # See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info # /dev/mapper/ol-root / xfs defaults 0 0 UUID=7a285d9f-1812-4d72-9bd2-12e50eddc855 /boot xfs defaults 0 0 /dev/mapper/ol-swap swap swap defaults 0 0 /dev/mapper/pool01-disk01 /u01 xfs defaults 0 0
Turn off swap:
[root@darlin-vce-db ~]# swapoff /dev/mapper/ol-swap
And (re-)create new swap:
[root@darlin-vce-db ~]# mkswap -c /dev/mapper/ol-swap 0 bad pages mkswap: /dev/mapper/ol-swap: warning: wiping old swap signature. Setting up swapspace version 1, size = 10485756 KiB no label, UUID=843463de-7552-4a73-84a6-761f261d9e9f
Then enable swap again:
[root@darlin-vce-db ~]# swapon /dev/mapper/ol-swap
And check swap again:
[root@darlin-vce-db ~]# swapon -s Filename Type Size Used Priority /dev/dm-1 partition 10485756 0 -1
Yes!!! That did the job. Easy does it...
