Correct - you need to setup ordinary SW raid - follow mdadm documentations. https://www.educba.com/what-is-raid-in-linux/ https://raid.wiki.kernel.org/index.php/RAID_setup in this order .... > It's just > that someone told me many years ago that hardware RAID was always > better than software RAID. > You probably do not remember that correctly - or you were talking to sales man, or something ..... - it is the other way around, at least for data storage. It is fine for OS drives and scratch disks where loss of data is not important OR with storage NAS appliance with proper support contract. In my humble experience (about hundred+ raid cards LSI/HP/IBM) - even with identical RAID cards purchased together - I could not rely on being able to access the data with different card and/or different server. SW raid, OTOH, just works everywhere, with any card in any server. -Tomas _______________________________________________ PLUG: https://pdxlinux.org PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
