Hello,<div><br></div><div>I have device which is partitioned with fdisk and formatted with mkfs.ocfs2. I wan't to remove that device from cluster.</div><div><br></div><div>What is the proper way to do that?</div><div><br>
</div><div>When I unmount device from all cluster nodes and try to deattach device from cluster, OCFS2 evicts one (of two) node from the cluster.</div><div><br></div><div>This is OEL 5.8 with OCFS2(1.4).</div><div><br></div>
<div>I've noticed this errors before node eviction:</div><div><br></div><div><div>Nov 5 13:35:28 l01ora3 kernel: sd 1:0:1:9: Warning! Received an indication that the LUN assignments on this target have changed. The Linux SCSI layer does not automatically remap LUN assignments.</div>
