I think this is different than the issue #599 so I create a new issue. I believe this is udev related or kernel config related.

My system is running gentoo-3.3.5 and udev package version is udev182-r3, and using git build for zfs.I can normally create pool and volume. But there is not /dev/zvol/* or /dev/zd* at all. Nothing even shows in /dev/disk/by-id. So I run "udevadmin monitor" to see what happen. When I start zfs, the udev events show:

KERNEL[2418.363575] add /devices/virtual/bdi/zfs-11 (bdi)
ACTION=add
DEVPATH=/devices/virtual/bdi/zfs-11
SEQNUM=2697
SUBSYSTEM=bdi

UDEV [2418.363895] add /devices/virtual/bdi/zfs-11 (bdi)
ACTION=add
DEVPATH=/devices/virtual/bdi/zfs-11
SEQNUM=2697
SUBSYSTEM=bdi
USEC_INITIALIZED=2418363830

KERNEL[2418.380939] add /devices/virtual/bdi/zfs-12 (bdi)

SUBSYSTEM=bdi

UDEV [2418.381255] add /devices/virtual/bdi/zfs-12 (bdi)
ACTION=add
DEVPATH=/devices/virtual/bdi/zfs-12

SUBSYSTEM=bdi
USEC_INITIALIZED=2418381189

That is it... Nothing else.

If I check the udev rules for zpool in /lib/udev/rules.d/60-zpool.rules, I read:
ENV{DEVTYPE}=="disk", IMPORT{program}="/lib/udev/zpool_id -d %p"

KERNEL=="[!0-9]", ENV{SUBSYSTEM}=="block", ENV{ID_ZPOOL}=="?", SYMLINK+="$env{ID_ZPOOL_PATH}"
KERNEL=="[0-9]", ENV{SUBSYSTEM}=="block", ENV{DEVTYPE}=="partition", ENV{ID_ZPOOL}=="?", SYMLINK+="$env{ID_ZPOOL_PATH}-part%n"
KERNEL=="dm-[0-9]", ENV{SUBSYSTEM}=="block", ENV{ID_ZPOOL}=="?", SYMLINK+="$env{ID_ZPOOL_PATH}"

So the subsystem should be "block", but my udev only shows subsystem as "bdi". So obviously nothing shows up in /dev.
Do I miss something or actually udev rules need some update?

Ok, more coming now. The top post is for a raidz2 case. So I want to know what happen to a single hard drive case.

Command: "zpool create storage /dev/hdd"
"udevadm monitor --property" outputs:

From zpool rules, I think we need ID_ZPOOL (please correct me if I am wrong). But we can see there is nothing named ID_ZPOOL in the udev events

instead, there are some related message(ironically, they are in the remove action!):

ID_FS_USAGE=raid

I really think that the udev rules are broken for udev-182 and kernel 3.3. Please correct me if I make any mistake

Ok, now I know what happens. I have to use "zfs create -V size volume" to make zvol avaliable. The zvol won't be created until "-V" switch is specific. This behavior should be documented.
