Hi Alwin, the usage jumps between different OSDs and everytime i see it, its on all 3 nodes of ceph on one osd per hardware node. HDDs are all the same. Is it possible to identify io usage inside ceph? On nodes there is only one node which shows round about 15MB/second from proxmox io view, but...

Hi, we are using proxmox 5.1-36 and ceph luminous. Sometimes we see higher io latency on some pgs and if i view iostat -x 1 in shell, i see one hardware drive from ceph with high awaits and %util. Is it possible to identify the vm which is the cause for the awaits and io usage? Best regards, Volker

Ok, thank you, we added a second private network to configuration of ceph. Regards, Volker

Hi, we have configured an external ceph with infiniband and added it to proxmox cluster. The ceph has a public network (172.16.65.0/24) and a cluster network (10.16.70.0/24). We also added the ceph pool to storage.cfg: rbd: ssd01 content images monhost 172.16.65.21 172.16.65.22...

Hi, 12 x Toshiba HK4R | 960GB Server specs: 2 x 14 Cores, 128 GB Ram

Hi, we setup a new environment with 3 nodes, debian stretch, proxmox 5.1, ceph luminous. Each nodes has 4 ssds for osd, summary 12 osds. From pg-calc we set a pg_num of 512 in ceph pool. The network for ceph is connected via infiniband. If we install a vm in ceph storage and make a dd inside...

Hi, we also see that before all nodes rebootet, the network device was in full usage while vm migration. We now use infiniband for migration traffic and dedicated lan for corosync. I think this task is done now. Regards Volker

Hi, we setup a new cluster on debian stretch with proxmox 5.1 and wanted to use ceph. While configuring setup we get the following error: root@cloud-node12:~# pveceph createmon unable to find local address within network '172.16.65.0/24' Our /etc/network/interfaces looks like: iface vmbr0...

What does this type of "totem" mean in corosync config? Here is always the ip of node01 totem { cluster_name: uCloud config_version: 8 ip_version: ipv4 secauth: on version: 2 interface { bindnetaddr: 172.16.70.11 ringnumber: 0 } } Shouldnt it be 172.16.70.0 on a /24...

Hi Folks, we have a proxmox cluster of 4 nodes, installed proxmox 4.4. While migrate vms from one node01 to another, all hardware nodes rebooted and i cant find a hint in a logfile what happened. As storage we configured ceph with 25 osds and 4 monitors (now reduced to 3). Any ideas where i can...

Thank you, Tom. Do we have to stop VMs on node we want to upgrade or can they run while we upgrade ceph from hammer to jewel? Later for reboots while mirgate to luminous we will migrate them to other nodes, of course :-)

Any ideas or tips you can send us? Or is it to easy in normal way? :-) Regards, Volker

Hi, we want to create two ceph pools. One with SAS osds, and one with ssd as osds. Is it possible to maintain that in proxmox 5.1 via webinterface or cli or do we have to configure one ceph configuration by hand? Regards, Volker

Hi, we have a running setup with: 4 Server Debian 8.x with Proxmox 4.4, CEPH "hammer" with 30 osds Last weekend and for further growing, we installed 4 server with debian stretch and proxmox 5.1. If we login to the proxmox panel the new servers are marked as "offline". I didnt see any hints...
