Linux localhost 2.6.25-gentoo-r4 #1 SMP Thu Jun 12 18:13:51 PDT 2008 x86_64 Intel(R) Core(TM)2 CPU 6700 @ 2.66GHz GenuineIntel GNU/Linux udev-128 with hal-0.5.11-r3 and revdep-rebuild and reemerge of hal I added a couple of hard drives and used the same rule "formula" as drives that showup, but the new drives don't show up. I turn on debugging with 'udevadm control --log-priority=debug' and even enter rule formatting errors in my udev config file, '/etc/udev/rules.d/10-mjbjr-udev.rules', but get no errors or new drives, old drives show up. It seemed to me that it just wasn't reloading the rules. Here's a older line from my config that works (from pre-udev-128, machine has not been rebooted). Drive was mounted (pre udev-128) and '/dev/jabba', '/dev/jabba1', and '/dev/jabba2' correctly exist, and drive works properly: BUS=="scsi", SYSFS{model}=="ST3200826AS", SYSFS{vendor}=="ATA", NAME="%k", SYMLINK="jabba%n", MODE="0774" Here's a line for a new drive that doesn't seem to be recognized, i.e., '/dev/greenst' doesn't exist, drive mounted manually and works: BUS=="scsi", SYSFS{vendor}=="ATA", SYSFS{model}=="WDC WD5000AACS-0", NAME="%k", SYMLINK="greenst%n", MODE="0774" Here's a line from my config that doesn't work for a new drive. This is my "control", it doesn't auto-mount and I haven't mounted it. It has been partitioned and formatted: BUS=="scsi"SYSFS{vendor"}="ATA", SYSFS{model}="ST3500320AS", NAME="%k, SYMLINK="roscoe%n" If I add 'PROGRAM="beep" ('beep' makes a beep tone and runs correctly when run by root) to the end of one of the above lines, I expect to hear a beep when I run: 'udevadm control --reload-rules' but I don't hear it. Which among other things leads me to believe that 'udevadm control --reload-rules' is not working properly, hence the 'strace', below. Running 'strace udevadm control --reload-rules' seems to show it opening up only the main config file, as far as I can tell: # strace udevadm control --reload-rules execve("/sbin/udevadm", ["udevadm", "control", "--reload-rules"], [/* 64 vars */]) = 0 brk(0) = 0x516000 mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7f76ef6ea000 mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7f76ef6e9000 access("/etc/ld.so.preload", R_OK) = -1 ENOENT (No such file or directory) open("/etc/ld.so.cache", O_RDONLY) = 3 fstat(3, {st_mode=S_IFREG|0644, st_size=156628, ...}) = 0 mmap(NULL, 156628, PROT_READ, MAP_PRIVATE, 3, 0) = 0x7f76ef6c2000 close(3) = 0 open("/lib/libc.so.6", O_RDONLY) = 3 read(3, "\177ELF\2\1\1\0\0\0\0\0\0\0\0\0\3\0>\0\1\0\0\0002\326\1\0\0\0\0\0@"..., 832) = 832 fstat(3, {st_mode=S_IFREG|0755, st_size=1273512, ...}) = 0 mmap(NULL, 2330808, PROT_READ|PROT_EXEC, MAP_PRIVATE|MAP_DENYWRITE, 3, 0) = 0x7f76ef397000 mprotect(0x7f76ef4c7000, 1048576, PROT_NONE) = 0 mmap(0x7f76ef5c7000, 20480, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED|MAP_DENYWRITE, 3, 0x130000) = 0x7f76ef5c7000 mmap(0x7f76ef5cc000, 16568, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED|MAP_ANONYMOUS, -1, 0) = 0x7f76ef5cc000 close(3) = 0 mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7f76ef6c1000 mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7f76ef6c0000 arch_prctl(ARCH_SET_FS, 0x7f76ef6c06f0) = 0 mprotect(0x7f76ef5c7000, 12288, PROT_READ) = 0 mprotect(0x7f76ef6eb000, 4096, PROT_READ) = 0 munmap(0x7f76ef6c2000, 156628) = 0 brk(0) = 0x516000 brk(0x537000) = 0x537000 open("/etc/udev/udev.conf", O_RDONLY) = 3 fstat(3, {st_mode=S_IFREG|0644, st_size=277, ...}) = 0 mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7f76ef6e8000 read(3, "# The initial syslog(3) priority:"..., 4096) = 277 read(3, ""..., 4096) = 0 close(3) = 0 munmap(0x7f76ef6e8000, 4096) = 0 getuid() = 0 socket(PF_FILE, SOCK_DGRAM, 0) = 3 sendto(3, "udevd-128\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\4"..., 292, 0, {sa_family=AF_FILE, path=@"/org/kernel/udev/udevd"...}, 25) = 292 close(3) = 0 exit_group(0) = ?

Ignoring all the text about specific rules, as this bug is about udevadm control. udevadm control --reload-rules does just what it tells: It reloads the rules into udevd. It does NOT re-process the devices! To do this you can issue udevadm trigger
Your rules can be improved: 1. Setting NAME="%k" is not needed, as this is default. 2. Setting MODE="0774" - for what do you need execute permissions on the dev-node ? 3. You overwrite all symlinks that are there before. Please use SYMLINK+= 4. BUS is deprecated, please use SUBSYSTEM Otherwise closing this bug, as udev is doing fine. udevadm trigger isn what you want.
