Nope, I've just say that local caching can be reason SM does not supports for shareable VDI. (you can not have local caching and shared VDI same time). On 25.05.2012 01:45, Carlos Eduardo Tavares Terra wrote: Do I need to enable local caching to use shareable VDIs? On Thu, May 24, 2012 at 7:3

Dudu, pelo que eu entendi a melhor solução seria os dois server ligados enviando dados no mesmo disco, usando o cluster, pois se usarmos a outra solução de cluster onde caso um nó falhar o outra entra pode ocorrer o risco de corromper dados.. ?? Att Franciane Pessanha On 05/18/2012 11:5

I tried to execute the vdi-set-shareable-true.py script, that i have found in the forum. But the result was not positive. I got SR_OPERATION_NOT_SUPPORTED error. [root@vmserver05 ~]# ./vdi-set-shareable-true.py -v 31e3186c-367f-4a87-b591-56844bb23420 FULL VDI entry = OpaqueRef:fda5a983-f234-c147-3

DRBD is not a solution for me. I will keep both VMs on, but just one of them will mount the filesystem. But, I could do that too using GFS2 or OCFS2. On Fri, May 18, 2012 at 11:53 AM, Mike McClurg wrote: > On 18/05/12 15:12, Carlos Eduardo Tavares Terra wrote: > >> Thanks... >> >> I really need
