As Nicolas said you can't do that with ext2, but you can with OpenGFS. OpenGFS is still in development, though, so I don't know how stable it is. I have not used it. You wouldn't be able to use RAID from both machines, though, so it would have to be something like this: Server1--[SCSI]--[disk with OpenGFS]--[SCSI]--Server2 Of course, if your disk dies you have no data... > Is it possible (case 2) to run a software raid1 over two > partitions (one on each raid5) from both computers at the same > time? As far as I know, no. Linux software RAID was not designed to be accessed from more than one machine. hmmm... maybe you could do it with hardware RAID. I hope that helps. -- Michael Wood <[EMAIL PROTECTED]> -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
