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>
