<div class="moz-cite-prefix">Documentation for v8.4 drbd.conf says
that minor-count can be a number from 1 to 1048575 but if I have
such global options:<br>
<br>
global {<br>
disable-ip-verification;<br>
usage-count no;<br>
minor-count 257;<br>
}<br>
<br>
drbdadm returns:<br>
<br>
root@63682049:~# drbdadm adjust all<br>
/etc/drbd.conf:6: minor-count 257 => 257 out of range [1..255].<br>
<br>
DRBD source code also does not indicate that I can set e.g.
minor-count 500;<br>
<br>
What is the difference between kernel module minor_count parameter
and minor-count option in config file? <br>
<br>
Thanks for help<br>

I would like to update DRBD from v8.3.10 to v8.4.4 in my
environment and have question about memory usage. <br>
<br>
I used minor_count=255 for DRBD (do not know how many resources we
will have in the running system) module parameter in DRBD 8.3 and
noticed that after update to 8.4.4, DRBD allocates about 256MB
memory in case of usage minor_count=255. Do I need set minor_count
to 255 in case when I do not know how many resources I will have
in the running system? Should I use
<meta http-equiv="content-type" content="text/html;
charset=ISO-8859-1">
minor-count option in config file? What is the difference? <br>
<br>
Additional when I try to attach (without starting replication
process) very big resources e.g. 16TB sometimes I get OOM killer
because of not enough memory. Does DRBD need about 32MB memory for
each 1TB of data assumption of using default values? <br>
<br>
Thanks in advance <br>
