[Linux-cluster] iscsi qdisk failure cause reboot

[brem belguebli]

Hi Jose,

check out the logs of the other nodes (the ones that remained alive)
to see if you don't have a message telling you that  the node was
killed "because it has rejoined the cluster with existing state"

Also, you could add a max_error_cycles="your value" to your <quorumd
device..../> in order to make qdisk exit after "your value" missed
cycles.

I have posted a message a few times ago about this feature
'max_error_cycles' not working, but I was wrong....Thx Lon

If your quorum device is multipathed, make sure you don't queue
(no_path_retry queue) as it won't generate an ioerror to the upper
layer (qdisk) and that the number of retries isn't higher than your
qdisk interval (in my setup, no_path_retry fail, which means immediate
ioerror).

Brem
