not sure which OS/distro this is from (I'm guessing centos 6.2), but:
all root files (dmidecode, etc.) are 0 byte size
vdsm log is missing

I think some sos plugins on this host are missing.

Comment 2 Ayal Baron 2012-07-05 07:55:07 UTC 
In addition to proper logs, What do you mean it goes offline?
The physical host shuts down?
vdsm stops?
It is non-operational in engine?
Comment 3 Robert Middleswarth 2012-07-05 22:54:42 UTC 
Itamar,

Please define what you mean by SOS plugins?

Ayal,
Host goes non-operational.

Thanks
Robert
Comment 4 Robert Middleswarth 2012-07-05 22:57:12 UTC 
I moved to a newer build and the one node hasn't gone offline since.  If it pop's back up what logs are you looking for?

Thanks
Robert
Comment 5 Dan Kenigsberg 2012-10-27 23:20:11 UTC 
I'd like to see the output of getVdsCaps on the non-op machine. Running `sosreport -o vdsm` should provide it (and more). Please reopen if needed.
