All, I'm having an issue with encrypted disk setup on my Dell M6600 laptop. During boot of Fedora 17 (originally installed from alpha, yum updated current ever since), I get prompted for the password but the device shown in the prompt changes. If it ends up picking md127p1 the boot device is not decrypted the devices but instead fails with a luks error trying to access the device. If I get prompted for the pass phrase for any other device, boot up is successful, including mounting the md127p1 partition. I've got four drives in the system: Two MSATA (one in the optical bay in a sata to msata converter) 120GB disks for OS and most other stuff (sdc and sdd), two Momentus XT 750GB for data (sda and sdb). They are set up as two mirrors in the Intel bios (Intel 82801 in a QM67). The boot raid consists of sdc and sdd. The drives are partitioned into 3 partitions: Number Start End Size File system Name Flags 1 1049kB 2097kB 1049kB bios_grub 2 2097kB 526MB 524MB ext4 ext4 boot 3 526MB 120GB 120GB Mount point for p2 is /boot, for 3 / The other raid consists of sda and sdb. The drives are partitioned into 2 partitions: Number Start End Size File system Name Flags 1 1049kB 17.2GB 17.2GB 2 17.2GB 750GB 733GB First partition is swap, the second is mounted under my home as /home/loony/data MD seems to look good too # cat /proc/mdstat Personalities : [raid1] md124 : active raid1 sda[1] sdb[0] 732571648 blocks super external:/md125/0 [2/2] [UU] md126 : active raid1 sdc[1] sdd[0] 117218304 blocks super external:/md127/0 [2/2] [UU] md127 : inactive sdc[1](S) sdd[0](S) 4776 blocks super external:imsm md125 : inactive sdb[1](S) sda[0](S) 5608 blocks super external:imsm unused devices: <none> Dracut related boot messages from a successful boot are: [ 3.399954] dracut: dracut-018-35.git20120510.fc17 [ 3.494352] dracut: rd.lvm=0: removing LVM activation [ 4.763255] dracut: Starting plymouth daemon [ 4.891705] dracut: rd.dm=0: removing DM RAID activation [ 5.322356] dracut: luksOpen /dev/md126p3 luks-a417a2f6-988b-49bf-be2e-e2cf34dcc160 none [ 11.592058] dracut: Checking ext4: /dev/mapper/luks-a417a2f6-988b-49bf-be2e-e2cf34dcc160 [ 11.596940] dracut: issuing e2fsck -a /dev/mapper/luks-a417a2f6-988b-49bf-be2e-e2cf34dcc160 [ 11.615698] dracut: /dev/mapper/luks-a417a2f6-988b-49bf-be2e-e2cf34dcc160: clean, 481162/7299072 files, 7478284/29175296 blocks [ 11.622597] dracut: Remounting /dev/mapper/luks-a417a2f6-988b-49bf-be2e-e2cf34dcc160 with -o ro [ 11.653308] dracut: Mounted root filesystem /dev/mapper/luks-a417a2f6-988b-49bf-be2e-e2cf34dcc160 [ 11.787906] dracut: Switching root The grub entry for the kernel is: linux /vmlinuz-3.3.4-5.fc17.x86_64 root=/dev/mapper/luks-a417a2f6-988b-49bf-be2e-e2cf34dcc160 ro rd.md.uuid=19fdc234:857a89e5:8831880f:c92180dc rd.lvm=0 rd.dm=0 SYSFONT=True rd.md.uuid=39828da2:5ba3ed07:e158fca9:b46f3ac3 KEYTABLE=us rd.md.uuid=92c96695:945f79c8:050bcb03:353f85c5 rd.luks.uuid=luks-6fbe3ef9-b08b-4d59-92fa-c4a4746c6817 rd.md.uuid=b0b5044d:22352807:56f708f9:0264f70c rd.luks.uuid=luks-a417a2f6-988b-49bf-be2e-e2cf34dcc160 LANG=en_US.UTF-8 The issue I have is that I get randomly asked at boot time for pass phrases for md127p1 (does not work), or for any of the other encrypted partitions (works). The error I'm getting with md127p1 appears only after 15-20 seconds and says that /dev/mapper/luks-a417a2f6-988b-49bf-be2e-e2cf34dcc160 wasn't found. If I enter a incorrect password when prompted for md127p1 it works as expected and prompts again after a second or two. Only if I enter the correct password, I see this error.. So, I have two issues. For one, why am I prompted for a different device on boot up? Shouldn't I always be prompted for the same device? And second, why does md127p1 fail? I somehow have the suspicion that the answer is in the grub kernel entry but I can't find any documentation if multiple rd.luks.uuid entries are valid, if the order matters and what is the appropriate entry to be there...
Technically, this doesn't belong on this list as F17 hasn't been released yet.
