[PVE-User] Cluster creation using specific IP or interface
Goal: to create a proxmox cluster using my 10gig backnet. Background: 10gig backnet network: 192.168.1.0/24 Accessible network: 10.135.164.0/24 Issue: When using ‘pvecm create clustername’ it chooses to use the 10.135.164.x address. Can anyone tell me how ‘pvecm create’ get the IP it is going to use? Can I influence it in someway?

Edit /etc/hosts so that your hostname resolves to an address in the 10gig network. ___ pve-user mailing list pve-user@pve.proxmox.com http://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-user
[PVE-User] High ceph OSD latency
Hello. I have a small proxmox/ceph cluster: - 3 x Dell CS24, each with: - 2 x xeon CPU - 24 Gbyte ram - 1 x 500Gbyte SATA disk (used for proxmox) - 3 x 2Tbyte WD2000F9YZ SATA Enterprise Edition (used for ceph OSDs) - 1 x Gbit ethernet (used for ceph and proxmox) - 1 x Gbit ethernet (used for vms ethernet) What is strange is that on OSD tree I have high latency: tipically Apply latency is between 5 and 25, but commit lattency is between 150 and 300 (and sometimes 5/600), with 5/10 op/s and some B/s rd/wr (i have only 3 vms, and only 1 is working now, so the cluster is really unloaded). I am using a pool with 3 copies, and I have increased pg_num to 256 (the default value of 64 is too low); but OSD latency is the same with a different pg_num value. I have other clusters (similar configuration, using dell 2950, dual ethernet for ceph and proxmox, 4 x OSD with 1Tbyte drive, perc 5i controller), with several vlms, and the commit and apply latency is 1/2ms. Another cluster (test cluster) with 3 x dell PE860, with only 1 OSD per node, have better latency (10/20 ms). What can i check ?

Re: [PVE-User] High ceph OSD latency
I will check, but the latency in osd tree is for each disk, and i have high latency on all osd; this is why i don't think that the problem is related to one host or disk.

POOMA U, but if you have one drive or controller that is marginal or failing, it can slow down the whole cluster. Might be worth while benching individual osd's ___ pve-user mailing list pve-user@pve.proxmox.com http://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-user
