Description Gordon Watson 2014-09-30 16:12:08 UTC

Description of problem:

This is a request to evaluate the potential of adding the 'perf' utility and/or the 'collectl' utility to the RHEV-H image.

The reason behind this is that there have been some specific occasions where having these utilities immediately available would have facilitated troubleshooting efforts.

I understand the need for these tools.

Currently we have about 10MB of space left on the ISO, due to implementation specific limitations. Which means that we can not add those tools.

Comment 7 Fabian Deutsch 2014-10-09 14:28:00 UTC

The limitation is about 256 MegaBytes (base 1024).

The installation will fail, because the iso image is larger than the allocated disk-space.

The only way to add more packages is by freeing enough space within the iso to add the desired packages.

Hello

When you say allocated "disk space" what do you mean exactly.
Gordon seems to have been able to create an ISO of 280MB.

Thanks
Laurence

Comment 9 Fabian Deutsch 2014-10-10 09:06:17 UTC

Yes, the iso can get larger, but it will not fit on the LV on disk.

The logical volume on disk, which holds the iso after the installation, is 256MB in size. An iso which is larger than this will not fit into it.

Test version:
rhev-hypervisor7-7.2-20151025.0.el7ev
ovirt-node-3.3.0-0.18.20151022git82dc52c.el7ev.noarch

Test steps:
1. Clean install rhev-hypervisor7-7.2-20151025.0.el7ev
2. Check perf in shell
3. #perf

Test result:
1. # rpm -qa perf
perf-3.10.0-325.el7.x86_64
2. perf command is provided.

So perf package is added in ovirt-node-3.3.0-0.18.20151022git82dc52c.el7ev.noarch now. Change the status to verified.
