Bug Critical Resolved Fixed Nathaniel Clark Frank Heckes soak Fri, 22 Jan 2016 11:23:24 +0000 Wed, 3 Feb 2016 16:17:57 +0000 Wed, 3 Feb 2016 16:17:57 +0000 0 4 <p>Nathaniel</p> <p>Could you advise on this one?</p> <p>Thanks</p> <p>Peter</p> <p>I don't see information on setup. A lot of setup scripts don't create a cache file on the hosts for zfs so automatic import doesn't happen <tt>-o cachefile=none</tt>. I don't see a link for the soak test scripts do you have the easily accessable? Where there any error when you tried to import them the first time?</p> <ul> <li>I attached the script library. Indeed the essential command in line <em>258</em>: <div class="preformatted panel" style="border-width: 1px;"><div class="preformattedContent panelContent"> <pre>on $host "zpool create -f $(poolname $target) -o cachefile=none $(dev $target)" </pre> </div></div> <p>create the zpool with no cachefile. <br/> This configuration option was decided to be used after some discussion about how-to import in HA set-up.</p></li> <li>What is the correct way to do it?</li> <li>No, errors occurred when explicitly importing the pool after the <em>first</em> boot after pool creation.<br/> And once this is done the pools are imported every the node is rebooted.</li> </ul> <p>Do you have a copy of the error you get when you import it the first time?</p> <p>The 'import' actions are logged in attached file 'cnventory-after-first-boot':</p> <div class="preformatted panel" style="border-width: 1px;"><div class="preformattedContent panelContent"> <pre>Script started on Fri 22 Jan 2016 03:02:04 AM PST ESC]0;root@lola-4:~ESC\[root@lola-4 ~]# zpool list no pools available ESC]0;root@lola-4:~ESC\[root@lola-4 ~]# zpool lisESC[ESC[ESC[ESC[KimESC[Kport -f soaked-ost2 ESC]0;root@lola-4:~ESC\[root@lola-4 ~]# zpool import -f soaked-ostESC[KESC[K6 ESC]0;root@lola-4:~ESC\[root@lola-4 ~]# zpool import -f soaked-ostESC[K10 ESC]0;root@lola-4:~ESC\[root@lola-4 ~]# zpool import -f soaked-ost1ESC[K4 ESC]0;root@lola-4:~ESC\[root@lola-4 ~]# zpool list NAME SIZE ALLOC FREE EXPANDSZ FRAG CAP DEDUP HEALTH ALTROOT soaked-ost10 4.53T 24.4G 4.51T - 0% 0% 1.00x ONLINE - soaked-ost14 4.53T 14.6G 4.52T - 0% 0% 1.00x ONLINE - soaked-ost2 4.53T 17.4G 4.51T - 0% 0% 1.00x ONLINE - soaked-ost6 4.53T 10.2G 4.52T - 0% 0% 1.00x ONLINE - ESC]0;root@lola-4:~ESC\[root@lola-4 ~]# # Reboot on more time ESC]0;root@lola-4:~ESC\[root@lola-4 ~]# exit exit Script done on Fri 22 Jan 2016 03:05:28 AM PST </pre> </div></div> <p>Actually no error occurred.
