Hi,
Currently on Ubuntu with Upstart when you invoke a restart like this:
$ sudo restart ceph-osd-all
It will restart all OSDs at once, which can increase the load on the
system a quite a bit.
It's better to restart all OSDs by restarting them one by one:
$ sudo ceph restart ceph-osd id=X
But you then have to figure out all the IDs by doing a find in
/var/lib/ceph/osd and that's more manual work.
I'm thinking of patching the init scripts which allows something like this:
$ sudo restart ceph-osd-all delay=180
It then waits 180 seconds between each OSD restart making the proces
even smoother.
I know there are currently sysvinit, upstart and systemd scripts, so it
has to be implemented on various places, but how does the general idea
sound?
