Depends on how easy it is to rebuild an OS from scratch. If you have
something like Puppet or Chef that configure a node completely for
you, it may not be too much of a pain to forgo the RAID. We run our
OSD nodes from a single SATADOM and use Puppet for configuration. We
also don't use swap (not very effective on SATADOM), but have enough
RAM that we feel comfortable enough with that decision.
If you use ceph-disk or ceph-deploy to configure the OSDs, then they
should automatically come back up when you lay down the new OS and set
up the necessary ceph config items (ceph.conf and the OSD bootstrap
keys).
Hello sir
This sounds really interesting , could you please elaborate how after reinstalling OS and installing Ceph packages, how does Ceph detects OSD's that were hosted earlier on this node.
I am using ceph-deploy to provision ceph , now what all changes i need to do after reinstalling OS of a OSD node. So that it should detect my OSD daemons. Please help me to know this step by step.
Thanks in advance.
