Subject: vstart: set a sensible default for ruleset-failure-domain
X-Git-Tag: v0.79~17^2
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=e4a8535ad123ee2ff9e3bf96bc75130f5739d717;p=ceph.git

vstart: set a sensible default for ruleset-failure-domain

Set ruleset-failure-domain=osd so that

  ./ceph osd pool create ecpool 12 12 erasure
  ./rados --pool ecpool put SOMETHING /etc/group

works by default. When using a vstart cluster the default failure
domain (host) won't work because all OSDs are in "localhost".
