Magnanimous Ladies and Gentlemen=0A=
=0A=
Due to an overly aggressive n00b rush, an ungraceful shutdown of our=0A=
Hosted Engine ensued.=0A=
=0A=
We were able to restore the Hosted Engine via RTFM.=0A=
=0A=
However the RHEL Host 6.6, upon which the Hosted Engine's integrity=0A=
depends, seems to have lost its network scripts. Forgive me for=0A=
inquiring about a topic that's probably been discussed many times.=0A=
=0A=
I restored the iSCSI and Management, Display, and VM VLAN's by=0A=
reconstructing the ifcfg scripts.  However we're not able to get vdsm=0A=
to restore what should exist.  So once RHEV-M returns the Host is of=0A=
course Non Operational.=0A=
=0A=
On the Host we have net_persistence =3D unified set in vdsm.conf.=0A=
=0A=
/var/run/vdsm/netconf/{nets,bonds} are empty.=0A=
=0A=
Though /var/lib/vdsm/persistence/netconf/{nets,bonds} contains=0A=
wonderful JSON.=0A=
=0A=
If files are copied from /var/run/vdsm/netconf/* to=0A=
/var/lib/vdsm/persistence/netconf/* then does this present a problem?=0A=
=0A=
How does persistence work with a stateful RHEL Host?=0A=
=0A=
I did not set up this Host so cannot vouch for its proper configuration.=0A=
=0A=
We've concerned about letting RHEV-M reconfigure the network of this=0A=
Host since if we lose the iSCSI bond that would be bad for the=0A=
manager.  We do not have another Hosted Engine capable Host at this=0A=
time :)=0A=
=0A=
If could you please assist I promise a cocktail or two the next time=0A=
you visit New Orleans.=0A=
