marsadm: new switch semantics on marsadm primary
...
Apparently, sysadmins often forget to execute "marsadm up mydata"
(or similar) after a failover.
Recall the failover command sequence:
"marsadm pause-fetch mydata; marsadm primary --force mydata"
Some months later, other sysadmins in the group are stumbling over
the very old "pause-fetch" after a regular planned handover via
"marsadm primary mydata". It works, but the former primary
(which is now secondary) does no longer fetch data, because of the
very old pause-fetch command which was never reverted.
Afterwards, /mars is filling up slowly over a long time.
Somewhen later (e.g. a few days), a monitoring alert "/mars too full"
is happening at midnight, leading to an unnecessary on-duty call.
A different type of monitoring could help, by not only
tracking the filling level of /mars, but also view-todo-fetch or
similar. However, some people dislike this, because there
exist operational use cases (like creation of backups) where pause-fetch
is executed _deliberately_ for a longer time.
Here is a workaround for a forgotten resume-fetch / up after
the first failover:
After the _original_ "marsadm primary" or "primary --force" has
succeeded by appearance of /dev/mars/mydata, we simply execute
the equivalent of "marsadm up mydata".
This changes the semantics of the "primary" command. Hopefully
no scripts on this world will break.
