I'm new to this list, so please excuse if this question was asked and probably solved elsewhere.
How is the suggested way to add a new lun, create a disk partition on, it, use this partition as physical volume, create a volume group and create logical volume ? I have done this on our three node (xen01-xen03) RHEL 5 cluster. I used a shared storage over fc ( HP EVA 8100 ) with multipath. - rescan echo "- - -" > /sys/classes/scsi_host/host0/scan on all nodes the devices appeared - done multipath mapping, and set multipath alias - on one node made the partition - on one node made the pv - on one node made the vg - on onde node made the logical volume but this volume can't be taken active: [EMAIL PROTECTED] kiswatch]# vgchange -ay Error locking on node xen01.tilak.ibk: Volume group for uuid not found: nEh1p8PzgfJO6Dedzjis1uDO6Yan2W5vew9ZlmZ3xyxbsgKclRwLCNAulf28UPqJ Error locking on node xen02.tilak.ibk: Volume group for uuid not found: nEh1p8PzgfJO6Dedzjis1uDO6Yan2W5vew9ZlmZ3xyxbsgKclRwLCNAulf28UPqJ the command lvdisplay on xen01 show the searched uuid: [EMAIL PROTECTED] kiswatch]# lvdisplay --- Logical volume --- LV Name /dev/lvm1/kiswatch_xvda VG Name lvm1 LV UUID ew9Zlm-Z3xy-xbsg-KclR-wLCN-Aulf-28UPqJ LV Write Access read/write LV Status NOT available LV Size 5.00 GB Current LE 1280 Segments 1 Allocation inherit Read ahead sectors 0 after restart of node xen02 the problem disappeared, but the node xen01 is very busy and should not be restartet. thanks in advance for any help -- Linux-cluster mailing list [email protected] https://www.redhat.com/mailman/listinfo/linux-cluster
