Description of problem: rhevm-appliance has no swap by default, this is contrary to https://access.redhat.com/solutions/15244 where a system with 16GiB of RAM should have at least 8GiB of swap. Version-Release number of selected component (if applicable): rhevm-appliance-20161214.0-1.el7ev How reproducible: Always Steps to Reproduce: 1. Install RHV using the hosted engine (rhevm-appliance) 2. launch free -m on the appliance Actual results: No swap Expected results: 8GiB+ swap Additional info: swap is required especially since additional tools must be installed on the manager (3rd party backup tools, etc) which might increase memory pressure.
Hey Ryan I am trying to understand whether this change has any impact on the documentation. The Planning and Prerequisites Guide already mentions the swap partition, https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.1/html/planning_and_prerequisites_guide/requirements#storage_requirements Although this section does not specifically mention the self-hosted engine, the latter references this section in the introductory chapter of the guide: https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.1/html-single/self-hosted_engine_guide/#chap-Introduction So, can you please clarify whether the table that appears in the guide was actually incorrect for the Self-hosted engine? For 4.2, is the table actually correct as it is?
The table is correct as-is This RFE is about adding a swap partition to the engine virtual appliance. It increases the storage requirements for the hosted engine (on shared storage) to 58GB instead of 50GB.
Verified with: rhvm-appliance-20171102.0-1 * disk resized to 58G (swap 8G)
