Hello, We have a 6 nodes cluster (PVE 5.2) with mixed storage: 20TB in Ceph and 10TB in a NetApp appliance, two separates lans with vlan, one for storage (LACP 2 x 10Gbps each server) and one for production (LACP 2 x 10Gbps each server) this core is 9 years old and we are planning to get a new...

Hi, finally solved the problem. As I have understood multipath-tools has a configuration, you can see it if you execute the command multipathd -k, then in the multipath prompt execute show config, then list the live configuration. In this configuration I saw that the blacklist section already...

Hi Hec, sorry, I was in worng. The wwid has to be the same for the same lun. Yes, I've installed the multipath utilities. The problemais the multipath.conf file: blacklist { wwid "*" } blacklist_exceptions { wwid "3600a09803830327241244735782f4e50" } multipaths { multipath { wwid...

Hi everyone, I'm trying to configure iscsi multipath but i'm not able. I have a Netapp with two controllers, one ip address assigned for iSCSI portal on each one, when I configure the portal in Proxmox the System automatically recognize both ip, and I can access and use the luns correctly. I...

Hi, sorry for no reply before, but i had spam problems, someone in my lan has been doing spam, a lot of spam... but solved by now. Our switches are two Extreme Summit X670 with 48x10Gbase-T ports, plus 4 SFP+... The switches had only one ip address configured for administration, this interface...

UUFFF... solved!!! The problem was the multicast. It was enabled in the switches, but in order to work the switch needs an IP address in each vlan, and there was NOT. When the support team has configured the IP addresses the quorum has reached, and now is well working. Thanks for all RobFantini!!

Yes, but which ip address, the pve hosts has two ip addresses. Thanks, I'm trying to ensure that multicast is permited in both lans (LAN and SAN), the swith support team is wotking to ensure it. About the traffic, the switches are Extreme Summit, I hope they can support more, more, a lot more...

Yes, but pve hosts are connected to two lans. I have 4 nics on each, 2 LACP groups, one for lan (172.22.0.0, eth0 and eth2) and one for SAN (172.18.0.0, eth1 and eth3). Which interface uses Proxmox for heartbeat (I guess that uses multicast)? Where can I found this configuration? In order to...

Hi, yes, all the nodes has four 10GbaseT, 2 for LAN and 2 for SAN (using LACP), moreover the Ilo connection. I can ping from all the lans the other nodes. All the nodes exists in /etc/hosts and dns resolution is working. Do you know which connection uses Proxmox for heartbeat? Can I specify it?

Hi, I updated (really new installation) from 3.4 to 4, but now I'm having problems with quorum. There are, by now, only 3 HP Proliant DL360 gen 8. I installed v4 without problems two days ago, and today the quorum has lost. I don't know why, I have been configuring Netapp iSCSI and NFS 4...

Hi Hec, I'm sorry, but I didn't read the NF Document from NFS, can you post a link, please? No, during test there were only v3 or v4 enabled, never both neither 4.1. No, Hec, I didn't set the Domain in idmap.conf. I'll set it. Here are the outputs: vserver show -vserver...

Yes, I agree with you, how important is this issue? If we plan to use nfs for big files there is no problem. But I were surprised when testing. I was planning to use iSCSI for images and NFS for backups, iso... but I read several articles about the major performance of NFS v4 vs iSCSI, that's...

Hello, I'm sorry, Manu, but i'm really surprised, as you can see in my statics the Qnap (TS-EC879U-RP, 8x3TB sata HD, it costs about 7.000€) NFS v3 reaches 55MB/s, the same proxmox server, same switchs, same files... but diferent NAS, Netapp (two controllers, 10Gb fiber connections, 24 x 1TB...

Hello, First I try with default parameters, then Netapp send me some modifications, last parameters were rsize=wsize=65536, and timeo=6000

Hello, I'm installing a new virtualization core: - 4 x HP Proliant Server (2 Intel Processors x8 cores and 96GB RAM each one), and another smaller one. With 4 10Gbase-T ports (two for LAN and two for SAN) each one. - 2 x Netapp (release 8.3, FAS2552 and FAS2520) with 4 10GbaseSX for node -...

Hi, It looks very interesting, I am installing two Netapp (production and backup) with four HP servers. Is there any easy way to install this plugin? Or a detailed maual for installation? I'm trying to install it but I'm not able to do that. I downloaded the plugin and tried to compile it and...

Hello, I am preparing technical specifications for the purchase of a new core server to work with Proxmox. Wiki says the hardware compatible is, in general, the hardware compatible with RHEL 6, but until I know Proxmox uses Debian. Do you think I should ask for the hardware has available...
