Description of problem: I've upgraded F14 to F15 beta. On restart it failed to boot. Version-Release number of selected component (if applicable): udev-167-4.fc15.x86_64 dracut-009-6.fc15.noarch How reproducible: Always Steps to Reproduce: 1. Boot the PC Actual results: dracut fails saying it cant find the root partition Expected results: Boot just fine Additional info: Now i start the machine by entering rdshell on kernel boot (grub), then executing lvm_scan, then type exit... and boot goes just fine to GDM I tried getting more info from udev (rdudevinfo) but i get much text that i cant handle and that text dont get logged anywhere. Here i inform all the data as suggested on http://fedoraproject.org/wiki/How_to_debug_Dracut_problems#AllInfo Command line: ro root=/dev/mapper/vg_server-lv_root LANG=es_ES.UTF-8 SYSFONT=latarcyrheb-sun16 KEYBOARDTYPE=pc KEYTABLE=es rdshell Fstab: # # /etc/fstab # Created by anaconda on Fri Dec 11 16:06:21 2009 # # Accessible filesystems, by reference, are maintained under '/dev/disk' # See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info # /dev/mapper/vg_server-lv_root / ext4 defaults 1 1 UUID=f44f6010-29e2-46eb-be96-5a0006267ddc /boot ext4 defaults 1 2 /dev/mapper/vg_server-lv_swap swap swap defaults 0 0 tmpfs /dev/shm tmpfs defaults 0 0 devpts /dev/pts devpts gid=5,mode=620 0 0 sysfs /sys sysfs defaults 0 0 proc /proc proc defaults 0 0 [root@server log]# dmsetup ls --tree vg_server-lv_swap (253:1) └─ (8:2) vg_server-lv_root (253:0) └─ (8:2) [root@server log]# blkid /dev/sda1: UUID="f44f6010-29e2-46eb-be96-5a0006267ddc" TYPE="ext4" /dev/sda2: UUID="eaxYEY-xrre-Ow6X-VeR9-ATbB-6Xh1-tVSZSy" TYPE="LVM2_member" /dev/mapper/vg_server-lv_root: UUID="134dffc3-9bfb-4827-bc98-c7fb96e6ae96" TYPE="ext4" /dev/mapper/vg_server-lv_swap: UUID="c52cd3af-1b38-484c-ba5e-28d5c4883c72" TYPE="swap" [root@server log]# blkid -o udev ID_FS_UUID=f44f6010-29e2-46eb-be96-5a0006267ddc ID_FS_UUID_ENC=f44f6010-29e2-46eb-be96-5a0006267ddc ID_FS_TYPE=ext4 ID_FS_UUID=eaxYEY-xrre-Ow6X-VeR9-ATbB-6Xh1-tVSZSy ID_FS_UUID_ENC=eaxYEY-xrre-Ow6X-VeR9-ATbB-6Xh1-tVSZSy ID_FS_TYPE=LVM2_member ID_FS_UUID=134dffc3-9bfb-4827-bc98-c7fb96e6ae96 ID_FS_UUID_ENC=134dffc3-9bfb-4827-bc98-c7fb96e6ae96 ID_FS_TYPE=ext4 ID_FS_UUID=c52cd3af-1b38-484c-ba5e-28d5c4883c72 ID_FS_UUID_ENC=c52cd3af-1b38-484c-ba5e-28d5c4883c72 ID_FS_TYPE=swap /etc/dracut.conf: [root@server log]# cat /etc/dracut.conf # Sample dracut config file logfile=/var/log/dracut.log fileloglvl=6 # Specific list of dracut modules to use #dracutmodules+="" # Dracut modules to omit #omit_dracutmodules+="" # Dracut modules to add to the default #add_dracutmodules+="" # additional kernel modules to the default #add_drivers+="" # list of kernel filesystem modules to be included in the generic initramfs #filesystems+="" # build initrd only to boot current hardware #hostonly="yes" # # install local /etc/mdadm.conf mdadmconf="yes" # install local /etc/lvm/lvm.conf lvmconf="yes" [root@server log]# cat /etc/dracut.conf # Sample dracut config file logfile=/var/log/dracut.log fileloglvl=6 # Specific list of dracut modules to use #dracutmodules+="" # Dracut modules to omit #omit_dracutmodules+="" # Dracut modules to add to the default #add_dracutmodules+="" # additional kernel modules to the default #add_drivers+="" # list of kernel filesystem modules to be included in the generic initramfs #filesystems+="" # build initrd only to boot current hardware #hostonly="yes" # # install local /etc/mdadm.conf mdadmconf="yes" # install local /etc/lvm/lvm.conf lvmconf="yes" [root@server log]# lvm vgdisplay --- Volume group --- VG Name vg_server System ID Format lvm2 Metadata Areas 1 Metadata Sequence No 3 VG Access read/write VG Status resizable MAX LV 0 Cur LV 2 Open LV 2 Max PV 0 Cur PV 1 Act PV 1 VG Size 148,85 GiB PE Size 4,00 MiB Total PE 38106 Alloc PE / Size 38106 / 148,85 GiB Free PE / Size 0 / 0 VG UUID Yw3lz0-joQX-2BCn-icxh-31rw-JLNn-rJYJXY [root@server log]# lvm lvdisplay --- Logical volume --- LV Name /dev/vg_server/lv_root VG Name vg_server LV UUID Pt8Pk0-3EbN-69Iv-RvL5-GT0G-vHEy-zyUrnX LV Write Access read/write LV Status available # open 1 LV Size 142,98 GiB Current LE 36602 Segments 1 Allocation inherit Read ahead sectors auto - currently set to 256 Block device 253:0 --- Logical volume --- LV Name /dev/vg_server/lv_swap VG Name vg_server LV UUID lveFp0-3tpM-r2WZ-WBKU-loEC-eEfs-aGqd2p LV Write Access read/write LV Status available # open 2 LV Size 5,88 GiB Current LE 1504 Segments 1 Allocation inherit Read ahead sectors auto - currently set to 256 Block device 253:1 Hope this helps to solve the problem.

Does it help, if you add "rd.lvm.vg=vg_server" to the kernel command line?
Nop. I tested with that, and doesnt work.
can you boot with "rd.debug" , do your magic to boot to the real root and then attach /run/initramfs/init.log to this bugzilla?
Created attachment 497114 [details] init.log from rd.debug Here is it. I doubt if it is a dracut or a udev problem. As far as i understand from the log, it seems dracut waits in a loop for the root to become visible, but it cant. I dont know if there is a way to enable udev log too to be included on the same init.log ??
can you give me in the dracut shell the output of: # udevadm info --query=all --name=/dev/sda2
Created attachment 497375 [details] Output of udevadm info --query=all --name=/dev/sda2
(In reply to comment #6) > Created attachment 497375 [details] > Output of udevadm info --query=all --name=/dev/sda2 ok, somehow ID_FS_TYPE is missing here... what is the output of: # blkid -o udev -p /dev/sda2
Output is : sudo blkid -o udev -p /dev/sda2 ID_PART_TABLE_TYPE=dos ID_PART_ENTRY_SCHEME=dos ID_PART_ENTRY_TYPE=0x8e ID_PART_ENTRY_NUMBER=2
There are advances on this? I think Fedora 15 final release should depend on fixing it! https://bugzilla.redhat.com/show_bug.cgi?id=617261 Right?
your sda2 is strange, has this been an extended partition once?
So, I see: [root@server log]# blkid ... /dev/sda2: UUID="eaxYEY-xrre-Ow6X-VeR9-ATbB-6Xh1-tVSZSy" TYPE="LVM2_member" [root@server log]# blkid -o udev .... ID_FS_UUID=eaxYEY-xrre-Ow6X-VeR9-ATbB-6Xh1-tVSZSy ID_FS_UUID_ENC=eaxYEY-xrre-Ow6X-VeR9-ATbB-6Xh1-tVSZSy ID_FS_TYPE=LVM2_member and # sudo blkid -o udev -p /dev/sda2 ID_PART_TABLE_TYPE=dos ID_PART_ENTRY_SCHEME=dos ID_PART_ENTRY_TYPE=0x8e ID_PART_ENTRY_NUMBER=2 and no ID_FS_TYPE in udev properties. kzak, any ideas?
Halard: No, it has been al LVM all the way
Javier, what is the output of: BLKID_DEBUG=0xffff blkid -o used -p /dev/sda2 and BLKID_DEBUG=0xffff blkid /dev/sda2 and fdisk -l /dev/sda and hexdump -C -n 512 /dev/sda2 and rpm -qf /sbin/blkid It really seems that there is any old partition table on sda2 (it was probably extended partition some time ago).
BTW, how old is LVM on the device? LVM should be able to wipe 8KiB from the beginning of the device, so there should not be any unexpected stuff.

Please, when nominating a bug as a blocker, note this, and explain why you believe it should be one, with reference to the release criteria - https://fedoraproject.org/wiki/Fedora_Release_Criteria . This makes it much easier to evaluate, especially when the bug has a long comment history like this one. This seems like an issue with your particular LVM setup; is there a reason to believe this bug would affect a wider range of systems? -- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers
Adam, i dont know really if i will affect a wider range of systems. nobody could yet give me a possible solution to my problem, so i cannot confirm is a issue "particular" to me. My LVM was created by Fedora tools (from version 14 or 13 i think). So i was hoping that Fedora 15 could "just work" with it? I dont know: the solution is to reinstall all my system? Or there is some workaround to avoid that?
This is not blocker from my point of view, your problem is very uncommon. LVM wipes first 8KiB on the device, the begin of your device is not wiped (see 0x55 0xAA, grub stuff, ...). It means that the device was modified later after LVM initialization. This fact was detected by libblkid and LVM signature was ignored. The solution is to remove the obsolete partition table from sda2. Backup first two sectors: dd if=/dev/sda2 of=~/backup bs=512 count=2 and wipe 2 bytes (0x55AA) from the device: dd if=/dev/zero of=/dev/sda2 seek=510 conv=notrunc count=2 bs=1 After this change the partition table will be invisible for libblkid. Please, be careful and think twice, you can lost your data.
Karel, it worked just fine!. Thanks and sorry to you all for the time you lost on this.
