Our current DRBD version is 8.0.16. We are constrained by the
linux kernel version we are using to upgrade to latest drbd
version.<br>
<br>
In this version after 70 - 80 failovers, we see that on board that
becomes cluster-primary FSCK -fy fixes some inodes.<br>
This change in inodes is not being replicated to standby board. <br>
If we perform failover at this stage, standby board that becomes
primary shows file corruption.<br>
File Corruption => Content of one file is seen in another file.
<br>
<br>
<strong>Some one can help us with DRBD version which fixed this
sync issue.</strong><br>
<br>
<strong>Solution:</strong><br>
In Run Level 3 we start a script to check the status of DRBD. If
it is not in expected state then we run recovery. This change
helped us clock 500+ failovers without any issue.</blockquote>
Version 8.2.5 and up seems to have verify to address this issue. I
run the verify regularly and before any planned switchover (that
safes a lot of bandwidth compared to a full sync). But that's not
available in the version you need to use.<br>
