We want to upgrade all LVS servers to stretch for multiple good reasons, including T171850 and the fact that it's the right thing to do. :-)
The process should be relatively straightforward. A couple of things to keep in mind:
| Status | Subtype | Assigned | Task | ||
|---|---|---|---|---|---|
| Resolved | MoritzMuehlenhoff | T177961 Upgrade LVS servers to stretch | |||
| Resolved | Vgutierrez | T190993 Upgrade pybal-test instances to stretch | |||
| Resolved | Vgutierrez | T191897 Reimage LVS servers as stretch | |||
| Resolved | ayounsi | T192087 Rename lvs* LLDP port descriptions after upgrading to stretch |
One significant thing to keep in mind is the interface naming changes. We'll be going from e.g. eth[0-3] to something like eno[1-2], ens1f[0-1], and we'll have to work that into all the magic that's configuring our per-vlan interfaces and doing all the custom network setup stuff, etc. Some of it could be easy to miss (breaks "silently", at least to some level of testing/scrutiny).
