[Spacewalk-list] Kickstart File - Increase Root Partition Size

[Sulove Khanal]

Hello,

 

Coming back to this, I had a few questions. I am trying to explicitly define the partitions now in my kickstart, creating these mount points (/boot, /, /home, and swap). I want to ensure I use LVM for all but the /boot partition, and give / 20GB of space. I have referenced the link in the below chain for kickstarts, as well as Stefan’s custom partition table.

 

The file system type on our other systems are xfs, so I am following in that same way. 

 
Does every LVM need to have a vg name specified?
Why do I need to define a volgroup?
Does this look correct below?
 

part /boot --fstype=xfs --size=1000

volgroup vg vg_main --pesize=4096

logvol / --fstype=xfs --name=lv_root --vgname=vgroot --size=20000

logvol /home --fstype=xfs --name=lv_home --vgname=vghome --size=1000

logvol swap --name=lv_swap --vgname=vgswap --size=1000

 

Regards,

Sulove

In a kickstart you cannot use autopart and also define any partition to be a particular size.  It is one or the other.

 

https://pykickstart.readthedocs.io/en/latest/kickstart-docs.html#autopart

 

I prefer to have more control over the disk layout, myself, and use the same method as Stefan.  But it depends upon your needs.  Sounds like you have a need to define your partitions.

 

Kickstart is powerful.  I have found only a very few limitations in it, and those have always been in the sysroot’d environment itself not in Kickstart.

Hello Sulove,

 

as far as I am aware, by default on RHEL it is using the full HDD as root after a /boot and a swap default.

 

This is how I do custom partition my servers:

 

Go to Systems --> Kickstart --> Profiles --> <Label> --> System Details --> Partitioning --> Partition Details

 

Enter

 

part /boot --fstype=ext4 --size=500
part pv.01 --grow --size=1
part swap --size=1000   --maxsize=2000 
volgroup vg_main --pesize=4096 pv.01
logvol /var/log --fstype=ext4 --name=lv_log --vgname=vg_main --size=1000
logvol / --fstype=ext4 --name=lv_root --vgname=vg_main --size=1 --grow
logvol swap --name=lv_swap --vgname=vg_main --size=2016

 

 

This creates:

- /boot 500MB as ext4

- swap between 1GB to 2GB (I think this is autoscaled to memory 1:1)

- /log 1GB as ext4

- / [root] for the rest

 

I hope this helps.

 

Best wishes,

 

Stefan

Betreff: [Spacewalk-list] Kickstart File - Increase Root Partition Size

 

Hello,

 

I’m looking to increase the size of the root partition in my Spacewalk kickstart file to 20GB. It is currently defaulted to 8GB when I boot up a new VM based off the kickstart file. The kickstart is also set to autopart –type=lvm. I am using Centos 7. I haven’t found how to increase the size of the root partition while still using the autopart option in the kickstart from my research online. 

 

Is this possible?

 

Thank you,

Sulove
