cloudstack stemcell root size volume

[mjsjinsu]

Hi there
I have a question about stemcell root volume size
I deployed CloudFoundry with cloudstack-cpi release based on cloudstack/xen
and used ubuntu stemcell 3192

I wonder if i resize root volume size
Unlike kvm based IaaS, cloudstack/xen base is didn't support flexible root volume size

I think root partition size 3GB is too small
It could be problem in the managing VM with bosh
I worried about root partition will be full
Also i know that, Most of job use attached data volume (ephemeral_disk and persisent disk)

I didn't know about stemcell bulid process and any infomation
Can you give me Opinion?

Hello @mjsjinsu
i think the root fs size should be ok.
As u know, all bosh releases uses ephemeral disk ( /var/vcap/data) for logs and temp files.
Globally, only base os packages and swap file are set on root disk.

I even have feedbacks from user considering 3Go to be to big for a template :-)

So you should not meet any issue. If u need more temp, just set a bigger ephemeral disk size
Dont hesitate to tell me if u meet a root fs file full, on a given bosh release
