I want to change the allocation of ost06 from 10.121.13.62@tcp to 10.121.13.28@tcp. The original configuration of ost06 was:<br/> Parameters: mgsnode=10.121.13.31@tcp failover.node=10.121.13.31@tcp ost.quota_type=ug<br/> and the ost06 was hosted on 10.121.13.62@tcp</p> <p>I have use tunefs.lustre to modify the ost configuration with this command line:<br/> tunefs.lustre --erase-param --mgsnode=10.121.13.31@tcp --mgsnode=10.121.13.62@tcp --param="failover.node=10.121.13.59@tcp ost_quota=ug" --writeconf /dev/mapper/ost06p1<br/> I want host the ost06 on 10.121.13.28@tcp with a failover on 10.121.13.59@tcp</p> <p>When I starting up, I see in the logs that the mds try to connect to OST0006 on 10.121.13.62@tcp and give some ost_connection error.</p> <p>Could you provide me the correct procedure to relocate the ost06 ?</p> <p>Thanks in advanced</p> Red Hat Enterprise Linux 5.7 + lustre 1.8.7-wc1 LU-1168
