<div> I want to test OST for Lustre(1.6.4.2, OS is CENTOS 2.6.9-42).I encounter some problems:<br />
<br />
1.First, I start one MDS on one machine and start two OST on another OSS machine,the first OST data is shared with one disk by ISCSI.<br />
<br />
2.Second, I stop(umount) one OST on OSS machine and deactive the OST on MDS machine(lctl conf_param test-OST0000.osc.active=0);<br />
<br />
3.Third,I install new machine and install Lustre, ISCSI. I start(mount) the first OST by ISCSI and active the OST on MDS machine(lctl conf_param test-OST0000.osc.active=1).It can work(mount successfully). But I find the OST is inactive device on CLIENT machine by command 'lfs df -h' and list files failed.</div>Johnlyahttp://wiki.old.lustre.org/index.php?title=User_talk:Johnlya&diff=4766User talk:Johnlya2008-05-21T08:56:55Z<p>Johnlya: please explain config with failover+mon</p>

<br />
Next I have installed mon, but I don't know config it with lustre. Please help me explain how to work. Thank you very much!<br />
<br />
The manual refers to "mon.trap" and "lustre.mon.trap",please tell where is in lustre. Thanks!<br />

manual:<br />
<br />
9. Copy the supplied trap generator script_ (mon.trap) to a proper location<br />
(/usr/local/lib/mon/)<br />
This Perl script_ is based on a script_ found on the Mon mailing list. Other script_s are also available there.<br />
10. Copy the provided Lustre monitor script_ (lustre.mon.trap) to the mon monitor directory(/usr/local/lib/mon/mon.d)</div>Johnlya
