    Default udev: don't delete Device

    Hello,

    i have 4 Harddisk-Boxes in my computer. In /etc/udev/rules.d/10-local.rules i put

    SUBSYSTEMS=="scsi", KERNEL=="sd?", MODE="0666", KERNELS=="3:0:0:0", NAME="sdB"
    SUBSYSTEMS=="scsi", KERNEL=="sd?[0-9]*", MODE="0666", KERNELS=="3:0:0:0", NAME="sdB%n", SYMLINK+="ftp1"
    SUBSYSTEMS=="scsi", KERNEL=="sd?", KERNELS=="4:0:0:0", NAME="sdC"
    SUBSYSTEMS=="scsi", KERNEL=="sd?[0-9]*", KERNELS=="4:0:0:0", NAME="sdC%n", SYMLINK+="ftp2"
    SUBSYSTEMS=="scsi", KERNEL=="sd?", KERNELS=="6:0:0:0", NAME="sdD"
    SUBSYSTEMS=="scsi", KERNEL=="sd?[0-9]*", KERNELS=="6:0:0:0", NAME="sdD%n", SYMLINK+="ftp3"
    SUBSYSTEMS=="scsi", KERNEL=="sd?", KERNELS=="5:0:0:0", NAME="sdE"
    SUBSYSTEMS=="scsi", KERNEL=="sd?[0-9]*", KERNELS=="5:0:0:0", NAME="sdE%n", SYMLINK+="ftp4", GROUP="ftpgroup"
    and in /etc/fstab
    /dev/ftp1 /home/ftp1 ntfs-3g defaults,users,rw 0 0
    /dev/ftp2 /home/ftp2 ntfs-3g defaults,users,rw 0 0
    /dev/ftp3 /home/ftp3 ntfs-3g defaults,users,rw 0 0
    /dev/ftp4 /home/ftp4 ntfs-3g defaults,users,rw 0 0
    So, when i put a disk into the first box, i only have to wait a littel an then simply tipping "mount /mnt/ftp1".

    That works fine, for a half year (or a little bit longer, i'm not shure).

    Normaly, when i umount a disk an then get it out, the device will disapear.

    But since some days, in some cases it will not. That means i have /dev/sdE and /dev/sdE1 (or /dev/sdB and sdB1), but there is no disk! What is going wrong there?

    (After an reboot, the device disapears.)

    At the Moment, i have no disk in the Box ftp4, but i have /dev/sdE (and /dev/sdE1).

    "udevadm info --export-db" says:

    P: /devices/pci0000:00/0000:00:1f.2/host5/target5:0:0/5:0:0:0/block/sdb

    E: ID_TYPE=disk
    E: ID_BUS=scsi
    E: ID_PATH=pci-0000:00:1f.2-scsi-3:0:0:0
    At the moment, i have no idea, why this is happening and i can't reproduce the failure.

    If you've an suggestion, i'm greatful.

    Thanks

    Hello,

    i think it was the libudev-devel - Security-Patch. I rolled it back, and since there, this failure dosn't appear.

    It's not nice, but for te moment, it works.

    regards jk
