- <li>Identify the EBOFS block devices. This is accomplished with symlinks (or actual files) in the <tt>ebofsdev/</tt> directory. Devices can be identified by symlinks named after the hostname (e.g. <tt>googoo-1</tt>), logical OSD number (e.g. <tt>4</tt>), or simply <tt>all</tt> (in that order of preference). For example,

For example,
<pre>
-mkdir ebofsdev
-ln -s /dev/sda3 ebofsdev/all # all nodes use /dev/sda3
-ln -s /dev/sda4 ebofsdev/0 # except osd0, which should use /dev/sd4
+mkdir dev
+ln -s /dev/sda3 dev/osd.all # all nodes use /dev/sda3
+ln -s /dev/sda4 dev/osd0 # except osd0, which should use /dev/sd4
</pre>
These need not be "real" devices--they can be regular files too. To get going with fakesyn, for example,
<pre>
# create small "disks" for osd0-osd3
for f in 0 1 2 3; do # fakesyn defaults is 4 OSDs
-dd if=/dev/zero of=ebofsdev/$f bs=1048576 count=1024 # 1 GB each
+dd if=/dev/zero of=dev/osd$f bs=1048576 count=1024 # 1 GB each
done
