Hi All:<br>
<br>
I have an OmniOS server running, under which zfs/zpool commands
have stopped responding. Any activities that involve the external
JBODs storage seem to hang. Is there a way to kill/reset this other
than rebooting the server?<br>
<br>
Here is some background:<br>
<ul>
<li>when logging in, the following is displayed:</li>
<ul>
<li>OmniOS 5.11 omnios-79686dc 2012.03.06</li>
</ul>
<li>uname -a</li>
<ul>
<li>SunOS lss-bkup301 5.11 omnios-eae537b i86pc i386 i86pc
Solaris</li>
</ul>
<li>hardware:</li>
<ul>
<li>server - SUN x4250</li>
<li>LSI SAS HBAs (I believe there are 5 in the system), they are
all of the same type (LSI SAS 9200-8e)</li>
<li>a combination of SUN J4400 JBODs, and one DataOnStorage
DNS-1660D</li>
</ul>
</ul>
<p>What I am seeing:<br>
</p>
<ul>
<li>The system is responding to input (I can log in, view files in
the the root pool, perform commands as long as they are
restricted to the root pool, etc.)</li>
<li>an "ls" command to filesystems on the external JBODs hang</li>
<li>zpool status commands on the external JBOD hang</li>
<li>the following is coming out on the console, rolling about
every 10-30 seconds:</li>
