I had this line in /etc/fstab when I upgraded from FEdora 21 to Fedora 22 last night: /dev/disk/by-id/wwn-0x50014ee102293fcc-part1 /mnt/point ext4 user_xattr,acl 0 0 As I recall, though it was a long time ago, the device path you see there was inserted by the "Disks" application when I originally configured the system to mount this filesystem. Before the upgrade, this worked just fine. After the upgrade, however, the system hung for a minute and a half trying to mount this filesystem (I hit ESC during the graphical boot and saw the mount job wait that long, which is how I know how long it took), and then failed to boot and fell into recover mode, i.e., prompted me for my root password. I'm not sure, but I think somehow the device path changed to /dev/disk/by-id/wwn-0x4597051696078737409x-part1 with the upgrade to Fedora 22. I thought the point of /dev/disk/by-id/whatever is that they're not supposed to change, but apparently not. Presumably others are going to be bitten by this and find themselves with systems suddenly unable to boot.
Same problem here. I referenced some disks/partitions by WWN and now, in F22, they're gone for different, unclear, WWN numbers. Checking with "hdparm -I /dev/sdX" confirms the WWN in F22 is not correct, at least assuming "hdparm" reads it properly. bye, pg
It seems bug #1227503 is duplicate of this one (or the other way around). In any case, there is explained the reason and, hopefully, there will be soon a solution. bye, pg
