<p class="MsoNormal">Hi list, <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have a question regarding filesystem consistency – say I choose async protocol (A) and the master peer node crashes fatally in the middle of write operation.<o:p></o:p></p>
<p class="MsoNormal">The slave peer node will then be outdated, but what happens to the filesystem on the top of the replicated block device – will I be able to restore data from the outdated peer?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">My understanding is that DRBD completely ignores the filesystem, so unless I choose synchronous replication protocol C, filesystem corruption can occur on the peer node.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Am I right?<o:p></o:p></p>
<p class="MsoNormal">Thanks,<o:p></o:p></p>
