Dear 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...
Greetings
Dominik
