Add option to override MGS host #132

Closed JohnGarbutt closed 4 years ago

JohnGarbutt commented 4 years ago

Added the config: DAC_MGS_HOST

By default it is localhost, which is existing behaviour where MGS always lives on the primary brick host.

We found operational issues of when to clean out the MGS after creating lots of filesystems. Eventually the MGS will fill up. As a work around, we allow operators to specify a custom location (host and device) for the MGS. This means you could easily rotate a single MGS (via change of config followed by reboot of dacd) that ensures the correct thing happens.
