That's correct, except not all of these guides discuss the drive serial |
15 |
number. If you want to ensure that different drives are mounted at |
16 |
different points, you have to rely on the device serial (since the /dev |
17 |
nodes are filled in order of the device connection, regardless of which |
18 |
drive it is). |

|
20 |
There are plenty of guides that mention how to find the serial number and |
21 |
how to write the correct udev rules, but most the guides are outdated and |
22 |
suggest use of the symlink udevinfo, which was removed upstream recently. |
23 |
So, to get a device's serial number, for example (replace /dev/sdb with the |
24 |
correct node) : |
25 |
|
26 |
# udevadm info -a -p $(udevadm info -q path -n /dev/sdb) | grep |
27 |
ATTRS{serial} |
28 |
|
29 |
and use the (first) serial that doesn't have colons and periods. Then for |
30 |
the udev rule you just need to include ATTRS{serial}==" 0000000000" |
31 |
|
32 |
This is also useful when you have external harddrives that use ext3 |
33 |
formatting and flashdrives that don't. |
