<html><head></head><body><div style="font-family: Verdana;font-size: 12.0px;"><div>Hi \
List,</div>

<div>&nbsp;</div>

<div>
<div class="linestyle1 colourline"><span>I&#39;m having a problem with metadata \
updating to drbd9 (from mainline included version 8.4.5 to 9.0.4-1, using 8.9.8 \
tools).</span></div>

<div class="linestyle2 colourline">The resources are using external metadisks.<br/>
&nbsp;</div>

<div class="linestyle2 colourline">F<span>ollowing the update procedure when \
creating/updating new md (drbdadm create-md&lt;res&gt;) I get:</span></div>

<div class="linestyle1 colourline"><span>v08 al_offset: expected -64, found \
8</span></div>

<div class="linestyle1 colourline">&nbsp;</div>

<div class="linestyle1 colourline">After checking the docs I did find that specifying \
drbd9 meta-disk dropped the flexible- part, but changing that has the same \
result.</div>

<div>&nbsp;</div>

<div>Doing a -v, the problematic command is (this is resource 6):</div>

<div>drbdmeta 6 v09 /dev/volume0/diskmeta flex-external create-md 1</div>

<div>&nbsp;</div>

<div>/dev/volume0/diskmeta is a 128MB lvm volume.</div>

<div>&nbsp;</div>

<div>One possibly interesting thing I find was that trying to look at origin of the \
error (user/shared/drbdmeta.c, line 511), it is from a switch case of value \
&quot;DRBD_MD_INDEX_FLEX_INT&quot;, with the INT part here suggesting to me that it \
thinks it&#39;s an internal metadisk?</div>

<div>&nbsp;</div>

<div>Anyone know what&#39;s going on here?</div>

<div>&nbsp;</div>

<div>J. Downing.</div>
