Package: xcp-storage-managers Version: 0.1.1-3 Severity: normal XCP cannot use iscsi block devices. Fails with iscsiadm: No active sessions. I ran the following commands trying to diagnose the problem: First introducing a SR and then creating a PBD with the needed configuration for the iscsi block device. These steps work fine but when I tried to plug the PBD I got the error: root at xcpcompute1:~# SR_UUID=$(uuidg...

...at would be the best way to remove an iscsi lvm storage from a server. (removing all reference to that storage etc.) The storage in question will be reset and reformated and used on a different server; so no LVM export is needed. Do I have to do lvremove ..., vgremove ..., pvremove ... and do an iscsiadm -m node -T ... -p ... -u and iscsiadm -m node -o delete -T ... -p ... in order to achieve that?

Are folks in the Centos community succesfully using device-mapper-multipath? I am looking to deploy it for error handling on our iSCSI setup but there seems to be little traffic about this package on the Centos forums, as far as I can tell, and there seems to be a number of small issues based on my reading the dm-multipath developer lists and related resources. -geoff Geoff Galitz Blankenheim
