Maybe I miss something but the page doesn't say anything about cli tools of the megaraid cards :-? >>> 3/ The manufacturer is enough linux-friendly so that in the event of a >>> problem you can contact them with no regrets :-) >> >> Hope I don't have to find out about that ;-) > > Bugs do exist also in good hardware, so better having a person over the > wire that at least understands what you are talking about :-) Thats absolutely true! >> Btw: Wouldn't it be better to use software raid?

My data isn't so important that it would justify restoring it with professional help. Still I have to do backups of the really important stuff to dvd or a seperate external drive... >> Thanks for all your help and advices! Ramon > > Just an additional note.

This should be no problem. I plan to use four slots without raid for mythtv. I already have a 4x 1.5 TB disks raid 5 and another 4x 2 TB disks raid 5. When I want to add more disks I can e.g. go for 3 TB disks and set 4 of them up as another raid5. Like this I can use disks with different sizes. I'm thinking of combining the arrays then to a lvm... But I don't know if this is a good idea as it adds more complexity :-? Best regards Ramon -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
