Hello,
I wanted to upgrade my F10 system to F11 (fresh install), but F11's
anaconda wouldn't detect my md RAID sets. I booted back into F10 and
after a bit of investigation, I discovered fdisk can't even read the
partition table of my 3 drive RAID 5 set. But, a look at /proc/mdstat
reveals md is happy.
I don't know what I should do to fix the problem. I don't have a ton of
experience with Linux RAID.
Here's the fdisk output:

Drives sdb, sdd, and sde are the ones with the supposed invalid
partition tables.
Here's the md status from the kernel's point of view:
[ranbir@ranbir ~]$ cat /proc/mdstat
Personalities : [raid1] [raid6] [raid5] [raid4]
md2 : active raid5 sdb[0] sde[2] sdd[1]
976772992 blocks level 5, 64k chunk, algorithm 2 [3/3] [UUU]
md0 : active raid1 sda1[0] sdc1[1]
104320 blocks [2/2] [UU]
md1 : active raid1 sda2[0] sdc2[1]
976655488 blocks [2/2] [UU]
unused devices: <none>
Is there actually a problem? If so, how do I fix it? Although I have
backups and could conceivable wipe the entire system clean during the
F11 install, I'd much rather have the md raid sets detected so that I
may choose to keep some of my partitions (e.g. /home).
Regards,
Ranbir
