We hope to haveredwrite disconnected stable and with the remaining features
implemented (cache persistence across reboot so changes to be written back
persist) in time for 1.6.

The more likely bottleneck is currently getting the DAFS-related issues in
1.5 worked out.

No, this isn&#39;t a DAFS server. As you&#39;ve said, the salvage fixes it - I<br>
wanted to confirm that it&#39;s a known issue, as I couldn&#39;t find it in the<br>
tracker.<br>
<br>
On another note, does anyone know what the status around stable<br>
read-write disconnect is? Might it make 1.6? What is the proposed<br>
release timeline?</blockquote><div><br>We hope to haveredwrite disconnected stable and with the remaining features implemented (cache persistence across reboot so changes to be written back&nbsp; persist) in time for 1.6. <br>
