Hi Alex,
interesting, I was not aware of ticket #1431! I considered PLM but assumed it involves some more work than the patch I sent out, as this feature is to be delivered in August. The remote fencing patch could be replaced with your PLM solution when it is ready and PLM seems to be the right place to add this functionality. It would be interesting to test your patch. /BR Hans ________________________________ Från: Alex Jones <ajo...@genband.com> Skickat: den 30 juni 2016 17:29:06 Till: Anders Widell; Hans Nordebäck; Mathivanan Naickan Palanivelu; Ramesh Babu Betham; praveen malviya Kopia: opensaf-devel@lists.sourceforge.net Ämne: Re: Opensaf-devel Digest, Vol 37, Issue 62 Yes, it uses libvirt for all the EE admin operations performed on the virtualized EE. There is no special fencing code in the PLM implementation, even for the current non-virtualized implementation. It's free with the PLM-EE hook in opensaf_reboot. So, if there are cases where opensaf_reboot is not being called for fencing in FM or elsewhere, we would need to change that. Alex On 06/30/2016 11:21 AM, Anders Widell wrote: > Ok, I see.
