The 'fake' RAID controller has two disks attached. Each is configured as separate RAID-0 stripe arrays - this is because the controller doesn't support JBOD pass-through.
This issue is caused by the LVM volumes on a fake-RAID device failing to be ready because the LVM VG_CADDY/rootfs is not created since the VG's container partition "/dev/mapper/pdc_ecjaiecgch4" does not get created: (initramfs) cat /proc/version Linux version 3.13.0-24-generic (buildd@panlong) (gcc version 4.8.2 (Ubuntu 4.8.2-19ubuntu1) ) #46-Ubuntu SMP Thu Apr 10 19:11:08 UTC 2014 (initramfs) cat /proc/cmdline BOOT_IMAGE=/vmlinuz-3.13.0-24-generic root=/dev/mapper/VG_CADDY-rootfs ro debug bootdegraded=true libata.force=noncq console=tty0 console=ttyS0,115200n8 [email protected]/eth0,@10.254.1.51/ --debug --verbose break=top nomdmonddf nomdmonisw (initramfs) dmesg | grep -C2 sdb [ 97.610562] scsi 11:0:1:0: Direct-Access ATA ST380011A 3.06 PQ: 0 ANSI: 5 [ 97.610762] sd 11:0:1:0: [sdb] 156299375 512-byte logical blocks: (80.0 GB/74.5 GiB) [ 97.610786] sd 11:0:1:0: Attached scsi generic sg2 type 0 [ 97.610893] sd 11:0:1:0: [sdb] Write Protect is off [ 97.610895] sd 11:0:1:0: [sdb] Mode Sense: 00 3a 00 00 [ 97.610942] sd 11:0:1:0: [sdb] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA [ 97.675153] sdb: sdb1 sdb2 sdb3 sdb4 [ 97.675669] sd 11:0:1:0: [sdb] Attached SCSI disk -- <27>[ 100.196769] systemd-udevd[176]: inotify_add_watch(7, /dev/sdb3, 10) failed: No such file or directory <27>[ 100.196845] systemd-udevd[168]: inotify_add_watch(7, /dev/sdb1, 10) failed: No such file or directory <27>[ 100.197798] systemd-udevd[177]: inotify_add_watch(7, /dev/sdb4, 10) failed: No such file or directory <27>[ 100.198351] systemd-udevd[175]: inotify_add_watch(7, /dev/sdb2, 10) failed: No such file or directory <27>[ 100.198375] systemd-udevd[179]: inotify_add_watch(7, /dev/sdc2, 10) failed: No such file or directory <27>[ 100.198911] systemd-udevd[180]: inotify_add_watch(7, /dev/sdc3, 10) failed: No such file or directory (initramfs) dmesg | grep 'too small' [ 100.346794] device-mapper: table: 252:13: dm-0 too small for target: start=13574144, len=142725198, dev_size=156298401 # fake RAID raw device (initramfs) kpartx -l /dev/sdb sdb1 : 0 2014 /dev/sdb 34 sdb2 : 0 1024000 /dev/sdb 2048 sdb3 : 0 12023809 /dev/sdb 1288192 sdb4 : 0 142725198 /dev/sdb 13574144 # same device through the device-mapper viewpoint (initramfs) kpartx -l /dev/mapper/pdc_ecjaiecgch Alternate GPT is invalid, using primary GPT. pdc_ecjaiecgch1 : 0 2014 /dev/mapper/pdc_ecjaiecgch 34 pdc_ecjaiecgch2 : 0 1024000 /dev/mapper/pdc_ecjaiecgch 2048 pdc_ecjaiecgch3 : 0 12023809 /dev/mapper/pdc_ecjaiecgch 1288192 pdc_ecjaiecgch4 : 0 142725198 /dev/mapper/pdc_ecjaiecgch 13574144 I've moved the VG to another disk on a plain PATA controller for now. I'll investigate more when I have time. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1358491 Title: [Trusty] fails to boot with kernels later than v3.11: systemd- udevd[133]: conflicting device node To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1358491/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
