Hi, I have 3 nodes with proxmox 1.8 with a Volume Group backed by 2 iSCSI LUN on a FreeNAS. All the three nodes sees the shared volumes and everything works.
The problem arised when I added a third LUN iSCSI target to the cluster and manually run vgextend <<VGNAME>> /dev/sdf (the new iSCSI added disk).
On the master node it worked but on the secondary ones the new iSCSI target was not visible and the GUI crashed with an error on vgs command (vgdisplay) because a disk of <<VGNAME>> volume was not found.
After several attempts I discovered that proxmox doesn't add iSCSI targets if added from master node if you not visit Storage page on every node.
At this point che correct (for me) proc to extend a volume group is:
- Master GUI: add iSCSI target
- Slave nodes GUI: visit storage page (proxmox will add iSCSI disk at this point)
- Master CLI: vgextend <<VGNAME>> <<NEW DISK>>
