<div>Package: mdadm</div><div>Version: 2.6.7.2-3</div><div>Severity: important</div><div><br></div><div>I used mdadm --detail --scan >> /etc/mdadm/mdadm.conf before rebooting to make</div><div>sure everything came back as configured. After rebooting I had two md devices</div>
<div>again, but both were auto-read-only and one was pointing to an old device that</div><div>shouldn't have been active. Every action I took with mdadm was prefixed with:</div><div><br></div><div>mdadm: metadata format 00.90 unknown, ignored.</div>
<div>mdadm: metadata format 00.90 unknown, ignored.</div><div><br></div><div>After some heart pounding, hair pulling and searching (ignoring any advice</div><div>to zero the superblock) I came across a post that suggested the parsing of</div>
<div>metadata=00.90 was at fault. Sure enough, I changed it to metadata=0.90</div><div>and everything's good again.</div><div><br></div><div><a href="http://ubuntuforums.org/showthread.php?p=6345457#post6345457">http://ubuntuforums.org/showthread.php?p=6345457#post6345457</a></div>
<div><div><br></div><div>After getting this sorted out I checked around further and found that mdadm -Ds</div><div>was the generally recommended way to add those settings, if one uses a</div><div>mdadm.conf file (bug 569359) and they format the metadata parameter with 00.90 just </div>
<div>like all other mdadm output, but for some reason assemble hates them. I also noted</div><div>that the /usr/share/mdadm/mkconf tool doesn't include the metadata parameter.</div><div><br></div><div>I see there is suppose to be a patch that is hopefully in the version of mdadm</div>
<div>for Squeeze already.</div><div><br></div><div><a href="http://neil.brown.name/git?p=mdadm;a=commit;h=d7ee65c960fa8a6886df7416307f57545ddc4460">http://neil.brown.name/git?p=mdadm;a=commit;h=d7ee65c960fa8a6886df7416307f57545ddc4460</a></div>
