I enabled mdmonitor, and created a raid1 while booted into fedora 20 and everything is wonderful. It recognizes the entry in fstab and boots no problem. (I'm not using the raid1 to boot from, BTY, just as a data disk). I then tried to boot the fedora 21 partition on the same machine (being sure to enable mdmonitor in it as well), and it never finishes booting. (Though a fedora 21 live USB stick boots fine). Has something changed in the vicinity of mdadm in f21? Do I need the initramfs rebuilt or something? Right now it stops booting with messages on the screen something like "/dev/sde is a large disk, trying to use READCAPACITY" and just sits there. (Where /dev/sde is one of the two disks I have in the array). -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
