Re: [Moosefs-users] supervise mfs daemons

[Michał B. <mic...@ge...>]

Option '-f' has never been used to start MooseFS processes without forking.

Options '-f' and '-s' have been replaced by parameters 'start', 'restart'
and 'stop'.

In order to run MooseFS processes in foreground use '-d' option. It is used
mainly for debugging but it also starts processes without forking. So we
assume that it would be somehow possible to use 'daemontools' with this
option of MooseFS.

But bear in mind that it would work only in chunkservers. If the master
server crashes you need to run "mfsmetarestore" before starting it again.
You could think about writing a script which automatically starts
"mfsmetarestore" and if there are no errors, starts the master server.


If you need any further assistance please let us know.

Kind regards
