ïDear Waldirio, Thank you for your description! (hell yea I can't portuguese but I understood it ;-)) I think you didn't get the point what I would do exactly... I try to boot from a ocfs2 fs. so the whole system is on a LV which is formated with ocfs2. I don't know if this possible... but I need a clustring filesystem because I dont have isci or something else... just 2 boxes which access the same scsi device...
