 |
|
Hi,
after updating udev-141 to udev-146-r1 my system hangs at startup with the following message: | Code: | ...
Checksum root filesystem
Failed to open device '/dev/sda3': No such file or directory
Filesystem couldn't be fixed
... |
How could I solve the problem?

| No, I didn't try. After downgrade to version 141 it works. But with version 146 not. |

| Please post the output of nl /etc/fstab ; nl /boot/grub/grub.conf ; find /dev -mindepth 1 -maxdepth 1 -name '?d?*' -ls, as run from the working udev. |

With udev-141 I get the following outputs:

| What kind of hardware backs sda? You may need to upgrade to a new udev and explore the dev that it creates, then adjust your kernel line accordingly. |

That's it.
I'm using the following udev rules: | Code: | # nl /etc/udev/rules.d/10-udev.rules
1 # Harddisc
2 SUBSYSTEMS=="scsi", KERNEL=="sd?[0-9]", ATTRS{model}=="SAMSUNG HD250HJ", NAME="hd/samsung_hd%n", SYMLINK+="%k", GROUP="disk", MODE="0660"
3 ACTION=="add" SUBSYSTEMS=="scsi", KERNEL=="sd?[0-9]", ATTRS{model}=="Maxtor 6Y080L0", NAME="hd/maxtor_hd%n", SYMLINK+="%k", GROUP="disk", MODE="0660"
4 ACTION=="add" SUBSYSTEMS=="scsi", KERNEL=="sd?[0-9]", ATTRS{model}=="Seagate FreeAgen", NAME="hd/freeagent", SYMLINK+="%k", GROUP="disk", MODE="0660"
5 # Flash
6 #SUBSYSTEMS=="scsi", KERNEL=="sd?[0-9]", NAME="usb/flash/%k", SYMLINK+="%k", GROUP="disk", MODE="0660"
7 SUBSYSTEMS=="scsi", KERNEL=="sd?[0-9]", ATTRS{model}=="SAMSUNG SUM-4G", NAME="usb/samsung%n", SYMLINK+="%k", GROUP="disk", MODE="0660"
8 SUBSYSTEMS=="scsi", KERNEL=="sd?1", ATTRS{model}=="Memorybird", NAME="usb/memorybird", SYMLINK+="%k", GROUP="disk", MODE="0660"
9 SUBSYSTEMS=="scsi", KERNEL=="sd?1", ATTRS{model}=="USB 2.0", NAME="usb/greenhills", SYMLINK+="%k", GROUP="disk", MODE="0660" |
I adjusted my /etc/fstab in the following way: | Code: | # nl /etc/fstab
1 # /etc/fstab: static file system information.
2 # $Header: /home/cvsroot/gentoo-src/rc-scripts/etc/fstab,v 1.14 2003/10/13 20:03:38 azarah Exp $

4 # noatime turns off atimes for increased performance (atimes normally aren't
5 # needed; notail increases performance of ReiserFS (at the expense of storage
6 # efficiency). It's safe to drop the noatime options if you want and to
7 # switch between notail and tail freely.
8 # <fs> <mountpoint> <type> <opts> <dump/pass>
9 # NOTE: If your BOOT partition is ReiserFS, add the notail option to opts.
10 /dev/hd/samsung_hd1 /boot ext2 noauto,noatime 1 2
11 /dev/hd/samsung_hd2 none swap sw 0 0
12 /dev/hd/samsung_hd3 / reiserfs noatime 0 1
13 /dev/hd/maxtor_hd6 /mnt/store ext2 noatime 0 0
14 /dev/fd0 /mnt/floppy auto noauto,user 0 0
15 # NOTE: The next line is critical for boot!
16 none /proc proc defaults 0 0
17 # glibc 2.2 and above expects tmpfs to be mounted at /dev/shm for
18 # POSIX shared memory (shm_open, shm_unlink).
19 # (tmpfs is a dynamically expandable/shrinkable ramdisk, and will
20 # use almost no memory if not populated with files)
21 # Adding the following line to /etc/fstab should take care of this:
22 none /dev/shm tmpfs nodev,nosuid,noexec 0 0
23 none /proc/bus/usb usbfs defaults 0 0 |
But I wonder why the symlinks like /dev/sda3 are not created any longer. Does someone know why? |

| Perhaps it's because you're changing NAME (which you should do - udev upstream discourages that). |

| No, I didn't change. Maybe I'm wrong, but from my understanding SYMLINK+="%k" should created e.g. a link /dev/sda3 to /dev/hd/samsung_hd3. |

That looks like attempt to change NAME. |

This works with udev-141. Maybe I have to read the udev documentation again.
At least I can boot now. Rest will follow. |
