Comment #12 on issue 787 by [email protected]: DRBD sync problems after
downgrade from DRBD 8.4 to 8.3
http://code.google.com/p/ganeti/issues/detail?id=787
Hi,
no I didn't modify them. The report above was while I tried manually
creating DRBD resources (which worked, although they were slow due to the
slow standard sync-rates).
Regarding DRBD/metadata:
I found that out reading the logs I posted above. It looks like the
creation and even the syncing of the logs goes fine, but than this happens
and ganeti deletes all disks and removes everything again:

As I understand the logs above (especially the lines between 151-230)
everything goes fine until the part posted here.
Another question: Kernels >3.8 (DRBD 8.4) aren't supported at the moment
(Ganeti 2.10.1), are they?
