Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.


I could not find anything "googleing" rcd_serial.
Do you have a link where I could get more information about it?

About my last big message the most important question is:
can I use iSCSI powered by drbd for sbd fencing?
is it a good solution?
what kind of iSCSI: active/active or active/passive?
any other hint for this solution?
