1. Why (when it cannot boot due to corruption) it NOT show anything
at
all in console?
I can get to grub menu (if moving fast enough), but if I continue boot I
see a blinking cursor for many minutes and not more. Grub options not
contain any splash/quiet parameters.
(exclusion for EDD message - it is meaningless, if I use edd=off - I get
only black console).
Where is a kernel boot logs/console output? Are it try to load initrd at
least?
2. How to set some timeouts for ha-agent NOT to try restart HE after 1-2
unsuccessful pings and 10 seconds outage?
For HE VM stability (not crash/broke fs) are more important instead
availability (I can live with unavailable it for 10-15 sec, but cannot
with broken VM).
3. I stop ha-agent, broker and HE VM on all (two) nodes. Fix a partition
in VM. Then I start ha-agent on nodes, and it BROKE VM fs AGAIN! (trying
to decide which VM are starting).
I fix VM fs again, put a cluster in maintenance mode, start a VM on one
node by hand, check it for status/health ok, and only then put ha-agent
in work (none) mode. Easy way to broke the cluster by crash HE VM fs (by
not put it to global maintenance mode).
