<p>We have 2 ocfs2 filesystems on our 6 node cluster running OEL5.10 that were created before indexed-dirs were active by default.</p>
<p><br>
</p>
<p>We were having lag in accessing sub directories that contained 10s of thousands of files, so thought adding the indexes would help, and it did for D/Q, we ran into this in our PROD environment.<br>

<p>adding the indexes to the first filesystem went fine, but adding to the 2nd resulted in errors

</p>
<p>The FS was fsck.ocfs2 prior to the attempt to add indexed-dirs and came back clean.</p>
<p><br>
</p>
<p>I then fsck'd again and removed the feature as it said it was enabled, and I didn't want corruption similar to as seen in :
