@justjosh we just had to do a tool stack restart on one (out of four) of the slaves. The other three just reconnected as soon as the master completed its restart. VMs on the slaves were completely unaffected. The VMs on the master had to have power state reset and then they started normally. I think most of the VMs ran auto fsck (CentOS 7) and one needed a little help with fsck but all recovered and nothing was lost.
