-------- Original Message -------- Subject: mdraid & dmraid, Fedora 11 & Fedora 13 Date: Tue, 25 May 2010 18:51:54 -0700 From: Joe Christy <joe@xxxxxxxx> Reply-To: joe@xxxxxxxx, Community support for Fedora users <users@xxxxxxxxxxxxxxxxxxxxxxx> Organization: Joe Christy Informatics To: Community support for Fedora users <users@xxxxxxxxxxxxxxxxxxxxxxx> Please excuse me, for I am a bear of little brain ... In the F13 release notes it says: Important — Systems with Intel BIOS RAID sets Fedora 13 uses mdraid instead of dmraid for installation onto Intel BIOS RAID sets. These sets are detected automatically, and devices with Intel ISW metadata are recognized as mdraid instead of dmraid. Note that the device node names of any such devices under mdraid are different from their device node names under dmraid. Therefore, special precautions are necessary when you migrate systems with Intel BIOS RAID sets from operating systems or versions of operating systems that use dmraid. Local modifications to /etc/fstab, /etc/crypttab or other configuration files which refer to devices by their device node names will not work in Fedora 13. Before migrating these files, you must therefore edit them to replace device node paths with device UUIDs instead. You can find the UUIDs of devices with the blkid command. I'm currently running F11 on a system w/ Intel BIOS RAID (1) [Lenovo ThinkPad W700] and remember problems w/ the SW raid under F10, and more problems w/ SW raid when I upgraded to F11. Unfortunately, the above warning is opaque to me. How can I tell if my F11 uses mdraid or dmraid? I used lvm to break my single raid partition into separate logical partitions and would dearly love to keep the data on the non-system logical partitions w/o restoring from backups, so I'm hoping that I don't need to jump through a lot of hoops to do so.
