Hi! Another question on SFEX: Recent SBD allows multiple (1-3) devices, and SFEX could be used similarily, but I wonder how to express a "majority" of sfex primitives in CRM (what I have in mind is this: When using two SFEX disks, the resources should stay up if one of those disks fails, but not if the other fails).
r on Disk A r on Disk B r on node X ---------------------------------------- owned by X owned by X run failed owned by X run owned by X failed run failed failed halt owned by !X <any> halt <any> owned by !X halt unowned unowned run failed unowned run unowned failed run Interesting case is when node X can access Disk A and not Disk B, but node Y can not access Disk A, but can access Disk B. Assume the resource is unused at startup: X claims r on Disk A, Y claims r on Disk B. Both would start r which is wrong. A solution for that? Background is if you have shared two storage systems in a SAN that mirror al data, the resources should not fail if one storage system fails.
