Yes i checked i dont think that is it. Is it normal for the vzsnap-proxmox1-0 to be stored on a iSCSI target?

Ok after some more digging i have realized that my master node named proxmox1 and one other node proxmox10 are have a problem with accessing the logical volume vzsnap-proxmox1-0 . I am wondering if this is because of the name of the name. I thought that i might have issues with using a "1" and...

This is a other thing that really confuses me. How come some nodes see different images on the same storage?

LoL but i do not know what that is?

HEY!!! After reading more about DM i was able to find 65 proxmox10:~# dmsetup info -j 254 -m 65 Name: OPENFILER-vzsnap--proxmox1--0 State: ACTIVE Read Ahead: 256 Tables present: LIVE Open count: 0 Event number: 0 Major, minor: 254, 65 Number...

Ok. Will do. Would it be safe to delete the DM-65?

I have done that ... They all can access all storages. Some of my nodes are 1.7 and some are 1.8 could this be the problem?

Any ideas?

It looks like different nodes are seeing different things? Should all the storage configuration be the same?

Also.. In a setup with multiple NIC's what nic is used to communicate with the Storage Machine? Can i create a bond that is only used for storage comunication?

Also i have been getting messages like this when i create a VM or Migrate a VM. Also when i click on hardware tab sometimes it times out. /usr/bin/ssh -t -t -n -o BatchMode=yes 192.168.2.80 /usr/sbin/qmigrate --online 192.168.2.81 220 /dev/dm-65: read failed after 0 of 4096 at 0...

Ahhh good idea:) Would having different network setups across the nodes cause my networking issues?

No i can't. For one some nodes don't have the same amount of PCI slots as others. I have different networking requirements for the different nodes. So the master dostn poll the node and display that nodes configuration? Also i have been having alot of network problems. I have been trying...

When i am logged into the master i only see vmbr0 and vmbr1 .. Even though the node i am trying to set the VM on has a vmbr2. If i log into this node directly i can setup the vmbr2 but not from the master node.
