Hello Florian,<br>
<br>
I do not remove the comments because I am not the only engineer
that manipulate the cluster and unfortunately the others do not "know"
Drbd so the comments may help us.<br>
<br>
In attachment you have a new config file, but actually I can not
validate.<br>
<br>
I want a "no limit" syncer parameter, so in drbd "no limit" = max =
700MB/s no ?<br>
My network dedicated to drbd is 2x1Gb/s this is less than 700MB/s okay
but I can use 2x10Gb/s link (approx 2500MB/s) and a BIG backend.<br>
<br>
I have the same problem with the 8.2.1, the 0.7.x see the metadata but
the 8.2.x no... in attachment you have the output.<br>
<br>
Best regards.<br>
<br>

<pre wrap="">Francis,
in case you're wondering why this list is being quiet about your issue, let me
guess it's a least partly because you haven't exactly made it easy for us to
even understand what's going on.
To illustrate, only to glean the differences between your 0.7.24 and your
8.2.0 config, I had to do this:
unzip drbd.conf.zip
for ver in 0.7.24 8.2.0; do
# strip comments, empty lines
grep -Ev "(^[[:space:]]*#)|(^$)" drbd.conf.$ver > drbd.conf.$ver.clean
done
diff --side-by-side drbd.conf.0.7.24.clean drbd.conf.8.2.0.clean | less

<pre wrap="">OK, Lars probably has a way shorter regexp for that grep, but you get the
picture. :-) But even after running it through that cruft, I'm having real
difficulty reading your config because your protocol option, and your disk,
handlers, syncer, startup, and net sections are configured on the resource
level -- and appear to be _exactly_ the same for every single resource.
You really need to set all of that once in the "common" section rather than
per resource; it will make your config a lot less verbose and much easier to
read. And everyone on this list is more likely to scan through 130 lines of
plain text config than through 677 hidden away in a zip archive, hint
hint. :-)

<pre wrap="">At first glance I can see that your syncer rate is way off at 700MB/s. I
highly doubt that your network is even coming close to that throughput. But
that's unrelated to the metadata conversion issue you appear to be having.

<pre wrap="">So, two suggestions:
- Skip 8.2.0 and go straight to 8.2.1. This is because of the nasty null
pointer dereference bug we had in 8.2.0 due to a change in the kernel crypto
API.
- Fix your config. Use the common section as intended, remove the "skip {}"
section included in the default config for illustrative purposes, remove
empty lines and comments, and re-post if your issue persists on 8.2.1.

<pre wrap="">Hello,
Lars, Phillip, Florian, do you have an idea why the 0.7.x find the
metadata magic number of the resource and the 8.2.x do not ?
Best regards.
