The root partition on builder0 to builder10 has about 8 GB of disk. We run into disk space problems often. Let's increase that to either 15 GB or 20 GB so these problems are avoided.
8G should be enough for the system, what is taking all the space ?
wouldn't it be better to mount a specific partition for that ?
We do have disk space in lvm, so it can be done without reinstalling the VM, but I would prefer know if we can get a better solution than increase / (purely to ease automation)
So this was easy:
ansible -i hosts -m shell -a 'lvresize /dev/mapper/vg_root_*-root -L +10G -r' 'jenkins_builders_rht:!int_rht_gluster_org'
That's likely enough, I can't add more without reinstalling (which is easy enough too)
