<p class="MsoNormal"><span lang="DE"><o:p> </o:p></span></p>
<p class="MsoNormal">every time trying to do zfs send | recv between OmniOS 151022.x and Nexenta 4.0.5x the Nexenta node crashes. This is very critical to us as we either want to use the OmniOS system for DR or migrate some files between the two. I raised a
ticket with Nexenta and they pointed me in the right direction. It seems that this problem had already been reported on Illumos mailinglist. So far no real fix has been provided.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><a href="https://www.mail-archive.com/discuss@lists.illumos.org/msg02699.html">https://www.mail-archive.com/discuss@lists.illumos.org/msg02699.html</a><o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The only way to fix this is either patch the receiving side (Nexenta). They have not done this for 4.0.5.x yet. But I was told that it will be done in 5.1 and it is planned to upstream the fix to Illumos.<o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">or the sending side. <o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">But the patch for the sending side (OmniOS) doesn’t work. The last thing on the post is an advice to implement this fix on the sending side:<o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">It seems that the problem not only affects zfs send | recv between Illumos based an Nexenta systems. Nexenta told us that they have a fix for NS 5.1 but currently upgrading to 5.x is not an option for us as this version has some limitations
and it currently doesn’t have this very important fix implemented:<o:p></o:p></p>
