Description

I accidentally deleted the original ticket (#14985) so I'll have to recreate this from my email history. The original ticket was filed by Yuri with this description:

VPS are not used and trustworthy because of low memory assignment.
We need to decide if number of VM's per host should be reduced in order to address this issues

Issue #14985 has been updated by Tamilarasi muthamizhan.

hi Yuri, brought this topic up in the weekly leads meeting and everyone agreed with the decision to go with reconfiguring the VM host to create a few VMs than now[like having to create 2 instead of 4], so as to increase the memory on the VMs and make it more usable for our nightlies testing.

I don't see anything about "bad alloc" here - is there an indicator that it's memory-related that you saw?

True Zack, but it's "reliably" hangs, I am testing another job now that hopefully will produce better error.

I manually enabled sar and told it to sample every second for these tests. Bear in mind that teuthology.front uses PST whereas the VMs use UTC.

Testing on a VM with 2GB RAM failed as expected:
http://qa-proxy.ceph.com/teuthology/issue_15052/2gig/teuthology.log
http://qa-proxy.ceph.com/teuthology/issue_15052/2gig/sar.txt
http://qa-proxy.ceph.com/teuthology/issue_15052/2gig/sa10

Testing on a VM with 4GB RAM failed as well:
http://qa-proxy.ceph.com/teuthology/issue_15052/4gig/teuthology.log
http://qa-proxy.ceph.com/teuthology/issue_15052/4gig/sar.txt
http://qa-proxy.ceph.com/teuthology/issue_15052/4gig/sa10

Testing on a VM with 8GB RAM passed:
http://qa-proxy.ceph.com/teuthology/issue_15052/8gig/teuthology.log
http://qa-proxy.ceph.com/teuthology/issue_15052/8gig/sar.txt
http://qa-proxy.ceph.com/teuthology/issue_15052/8gig/sa10

The sa10 files are sar's binary logs. They can be queried to e.g. show only memory stats via: sar -f /path/to/sa10 -r

We've decided to move to 4GB VMs. All even-numbered VMs have been marked down. The teuthology change (just merged) is here:

Should we leave this open until we decide what to do with the unused disks?
