[gentoo-user] Udev rules for identical hard drives

[gentoo-user] Udev rules for identical hard drives

[Alex Schuster]

Hi there!

I do not understand the numbering of my hard drives. There may be some
inherent logic, but whenever I make some changes, like replacing drives,
or changing BIOS settings, the order changes. Maybe it's even more random.

So I made some udev rules like this, and my drives are called /dev/hd1,
hd2 and hd3:

SUBSYSTEMS=="scsi", KERNEL=="sd?", ATTRS{model}=="SAMSUNG HD154UI",
SYMLINK="hd1"

This works fine, and this way I can address them in scripts, smartd and
hdparm config files and such. But now I have two identical drives. I had
this before with the drive above, but while being identical models, the
two drives differed a little in size, so I just had to add ATTR{size}.
This does not help with my current drives, and I find nothing
in /sys/block/sd?/device/ that differs. Could there be another way to
distinguish the drives, like looking at the partition scheme or something?

If you want to distinguish partitions, I would recommend using labels
(in fstab too); those never change unless you specifically change
them. Then, no matter how you put them in your machine, they will get
mounted correctly, and then you don't need to fuzz with udev rules.
Also, as a superficial bonus, they get mounted using the label and it
looks nice in your file browser.

The drives themselves I see no reason to recognize them, why do you
need to do that?

Oh, and I forgot; doesn't the links in /dev/disk/by-id,
/dev/disk/by-label, /dev/disk/by-uuid do what you want to?

I'm aware of that, and I would use this, if I weren't using LVM and
encryption on top of that. So I do not deal with raw partitions at all,
but with partitions like /dev/mapper/root or /dev/weird/portage.

Oh, this gives me an idea of what to use as workaround: If what I would
like to have is not possible, I will add a little start script
in /etc/local.d/ which calls pvscan to check which volume groups belong
to which drives, and creates the symlinks.

Well, I don't really *need* this. But it's convenient.

- I have a monitoring plasmoid on my desktop that shows whether a drive
  is active or on standby, and also gives the temperature of my always
  running system drive. If there were a mixup, calling hddtemp on a
  sleeping drive would wake it up.

- I have different idle time settings in /etc/conf.d/hdparm, and I spin
  down two drives immediately after I have booted.

- Same goes for a little script I use for suspend-to-ram. It makes use of
  the rtcwake command to make the PC wake up in the morning (before I get
  up), and along other stuff spins down drives.

- And I have different settings in /etc/smartd.conf.

Those seem to list partitions only, not whole drives. A label for a drive
would be nice to have.

Uh, and here's the little start script I just wrote. No idea why I call
my drives hd1 to hd4 instead of using the name of the only volume group
they have, but I'll keep it like that for now.

str=$( pvscan )

hd()
{
	hd=$( echo "$str" | grep "$1" | head -n 1 | awk '{print $2}' )
	echo ${hd//[0-9]/}
}

ln -s $( hd "weird " ) /dev/hd1
ln -s $( hd "weird2" ) /dev/hd2
ln -s $( hd "weird3" ) /dev/hd3
ln -s $( hd "pata1"  ) /dev/hd4

I'm pretty sure whole drives are there also:

$ ll /dev/disk/by-id
...
ata-SAMSUNG_HD160JJ_S08HJ10YC13279 -> ../../sda
...

That's a whole drive right there.

Wow, now I feel really stupid :) You are so right, they are there, and I
don't why I overlooked them... too many entries there maybe, I have 140.
But still. Stuuupid!

I looked again in the terminal at what I did this night, and at least
feel a little less stupid now. I had searched for my /dev/sdd drive, and
this one just has no label. Only its partitions do, they appear twice, as
ata-SAMSUNG_SP1614N_0735J1FW815459-part[15678] and
wwn-0x50f0000000000000-part[15678].

This drive is an older PATA drive, maybe that's the difference?

Check out the very nice 'lsdrv' script by Phil Turmel. Run it, save a
copy of the output for bad times.

That doesn't work here, and I do not understand why. In line 305 it tries
and fails to create /dev/block, which is already existing.

if not os.path.exists('/dev/block'):
	os.mkdir('/dev/block', 0755)

Uh, is this a python bug? It works fine with python 2.7, but not with
3.2. But os.path.exists() is quite a basic function, if that wouldn't
work, I'd expect all things to break, including emerge.

Nice script. Much similar to lshw I think, but it shows more stuff, like
LVM names and UUIDS. Thanks!

Dunno about the python-3.2 thing. Are you set to use 3.2 by default?
(How aggressive of you!) ;-) I'm set to use 2.7 as default which I
think is the overall recommendation of dummies like me:

c2stable ~ # eselect python list
Available Python interpreters:
  [1]   python2.7 *
  [2]   python3.2
c2stable ~ #

The script has been around awhile and updated now and again. Possibly
it's just not tested with python-3.2?

Anyway, the folks on the mdadm RAID list often ask people who had a
RAID completely fail if they had the info this script provides taken
from prior to the crash so I do it for all my machines and then keep
the output in my GMail account for safety.

HTH,

  You can get the ATTRS{serial} (i.e. serial number).  See the printer
example at http://www.reactivated.net/writing_udev_rules.html and adapt
to your hard drive.  Serial numbers should be unique, even amongst
otherwise identical drives...

======================================================================
I power on my printer, and it is assigned device node /dev/lp0. Not
satisfied with such a bland name, I decide to use udevinfo to aid me in
writing a rule which will provide an alternative name:

    # udevinfo -a -p $(udevinfo -q path -n /dev/lp0)
      looking at device '/class/usb/lp0':
        KERNEL=="lp0"
        SUBSYSTEM=="usb"
        DRIVER==""
        ATTR{dev}=="180:0"

      looking at parent device
'/devices/pci0000:00/0000:00:1d.0/usb1/1-1':
        SUBSYSTEMS=="usb"
        ATTRS{manufacturer}=="EPSON"
        ATTRS{product}=="USB Printer"
        ATTRS{serial}=="L72010011070626380"

My rule becomes:

    SUBSYSTEM=="usb", ATTRS{serial}=="L72010011070626380", SYMLINK+="epson_680"

I thought so too, so I was surprised to find a few weeks ago that 
something had set 3.2 as default. With 3.2 I get similar results to 
Alex's but with 2.7 it works properly.

That's exactly what I would like to have! I have a working solution, but
using UDEV would seem more adequate.

But: I cannot find a serial number for my hard drives in the output. And
shouldn't there be a file named 'serial' in /sys? I have some, but not
for my block devices, only for USB and in /sys/{bus,pci}/drivers/.

BTW, sys-fs/udev-187 does not have the 'udevinfo' command, it seems to be
'udevadm info' now.

I haven't found any official Gentoo documentation that says we should
be using anything other than 2.7 as default.

If something changed a setting like that (during an install or
otherwise) it could be quite frustrating to find. Sorry for your
problems.

I've seen one package in an overlay that's starting to look for python-4. Scary!

Um, but did you use eselect to make 3.2 the current version?

Portage should work well with 3.2 now, but I wouldn't wonder much if
something would break. I don't mind much about this, when it happens I
file a bug report, and use 2.7 again. But the problem with
os.path.exists() seems weird to me.

I guess so. Hmm, does anybody want to provide an ebuild on
bugs.gentoo.org for it? It would be nice to have it in portage.

Not all drives supply this. I have a pair of Seagate drives and a pair of
WD drives. Neither drive is distinguishable from its twin with udev
attributes.

udevinfo disappeared a long time ago. I wrote a script called udevinfo to
call mdadm info so that I didn't need thchage my setup, it is dated

Nope.  I didn't notice he was trying to use 3.2 until after I hit send. 
Bad thing about emails, you can't delete them after they are sent.  :/ 

I thought we were supposed to have 2.7 selected for the default and I
guess I just assumed that was what he was doing.  I guess I am not the
only one getting ahead of myself.  lol

In the good old days you could compose offline, and not send them
until the next time you dialed up, so you had ample opportunity to
retract what you had written if you had second thoughts. :)

In the gmail web interface, you can able "Undo send" feature in Labs,
which will give you 5 or 10 seconds to change your mind after clicking
"send" on a message.
