When I run 'drbdmanage list-nodes' on my fresh proxmox drbd9 install I get this:
Code:
root@node1:~# drbdmanage list-nodes
+------------------------------------------------------------------------------+
| Name  | Pool Size | Pool Free | Site |                               | State |
|------------------------------------------------------------------------------|
| node1 |   2048000 |   1501184 |  N/A |                               |    ok |
| node2 |   2048000 |   1264230 |  N/A |                               |    ok |
| node3 |   2048000 |   1264230 |  N/A |                               |    ok |

Why is the pool free size on the first node different?

Beside that, the disk performance is very bad. On the previous install of our cluster it was around 100MB/s and now it is 8.9MB/s. We use 3 WD blacks in RAID0 (hardware raid). It looks like the problems started after a VPS clone yesterday.
