SSD Caching software solution

Hello,

There is seems more and more stable solution for SSD caching without hardware raid card.

I'm need SSD caching for RAW partitions (Windows) is there any of there SSD caching that's could work with RAW instead of filesystem ?

ZFS have interresting features too, but seems also work only with his filesystem ? (never test it just look at man and some webpage)

The goal is to have SSD caching with Software Raid and RAW partition for Windows VM guest host.

Thanks

Hello,

we running 5 Nodes in a proxmox 2.0 cluster with 3.1. We have on all nodes the Community Subscription. I don't know, we never have done an Upgrade before from a cluster. So what is the right way to do that. Can we go on every node in the Webinterface on upgrade, and that it's. (Maybe an reboot when updateting kernel an qemu). Or is there a special to observe. Must every node have the same version of Proxmox?

Thanks for the information

Hello,

at customer after update from 3.1 to proxmox 3.2 we have a problem to backup one VM with snapshot (VM is an Gentoo, up to date). On my homeserver the same problem, but the VM is an Ubuntu 12.04 LTS. At my homeserver the backuprocess does not work sporadically. Sometimes it work.
But on customers server, every backup from the vm let the vm crash. It is a little Cluster with two nodes. On Customer we have the Basic Subscription. So updates should be ok. Here are the logs from the backups:

Getting started with PVE storage model - software RAID5 array and storage concepts

March 23, 2014, 6:31 pm

Hello,

So following up my "debuts" with proxmox, I am now trying to grasp the concepts and storage model of PVE. First of all, I'd like to add a bunch of SATA drives (6 of them) that were previously assembled as a software RAID 5 array under Slackware Linux. I would like to reassemble them and reuse the array under a VM running CentOS 6.5

Some questions:

1. Software arrays do not seems to be supported in proxmox at all. How should I proceed? Should I assemble them with mdadm at proxmox's level then add the md device in the vmnumber.conf file with something like: ide0: /dev/md0 so the VM sees it as a single large 10TB drive, or should I pass-through all 6 drives unassembled to the VM then assemble the array at the VM level?

2. I have tried the second option (pass-through all 6 drives unassembled to the VM then assemble the array at the VM level) by adding these lines in the VM config file

ide0: /dev/sdb
ide1: /dev/sdc
ide2: /dev/sdd
ide3: /dev/sde
ide4: /dev/sdf
ide5: /dev/sdg

but unfortunately, in proxmox, I only see 4 of them. I booted up the VM and confirm that only 4 of the 6 drives are passed to the VM. Obviously, the array is not started because there are too many missing drives. Why are only 4 of the 6 drives passed to the VM by PVE? Is it a misconfig of some sort or are VM limited to 4 physical drives?

EDIT: User tom at thread http://forum.proxmox.com/threads/159...e-pass-through clearly stated that

Quote:
you cannot use ide4. there are only 4 ide devices allowed - ide0, ide1, ide2 and ide3.
So how do I add more than 4 !??!

Thanks guys!

OpenVZ migration fails when no quota enabled

March 24, 2014, 1:33 am

Hi,

Using Proxmox VE 3.2, latest updates applied, no-subscription repo, in a 10-node cluster setup.

I've disabled disk quota in /etc/vz/vz.conf by setting DISK_QUOTA=no, cause I do not need
OpenVZ disk quota. I use OpenVZ for storage servers and allow it to take all of my disk space.

I use external GlusterFS server to store VMs. No HA, no rgmanager, just VMs on GlusterFS.

When I try to migrate OpenVZ VM to another node, I get:
Code:
Mar 24 11:57:19 starting migration of CT 81141 to node 'pve-server-NN' (XXX.XXX.XXX.XXX)

Mar 24 11:57:24 ERROR: Failed to dump 2nd level quota: vzquota : (error) Can't open quota file for id 81141, maybe you need to reinitialize quota: No such file or directory
Mar 24 11:57:24 aborting phase 1 - cleanup resources

TASK ERROR: migration aborted
pve32-vzmigrate-trouble.png

This is strange, cause if there is no quota enabled, vzmigrate should NOT check for it. :(

And, yes, if OpenVZ disk quota is enabled, migration goes fine.

Could you please help me with that? What should I do to make my VMs migrate across nodes smoothly, even if disk quota is disabled?

Thanks in advance!

New 3.2 installation, cannot connect via browser

I installed Proxmox VE 3.2 for the first time on my home server hardware today. I first attempted to install via USB key, but that didn't work at all... the installation timed out trying to "unmount cdrom". Well, I went back to the stone-age and burned a CD for the install ISO and it installed correctly, and without issue at all.

I now cannot connect to the Proxmox host via my PC on the local network, but I can ping the host IP address from my PC no problem. Checking ifconfig on the proxmox host, the network adapter is working and has an IP address on the local network (statically assigned, 192.168.1.100). This correctly correlates with my router IP assignment list. Additionally, from the host I am able to ping 4.2.2.2, yahoo.com, and my personal PC on the local network.

Here is the output from ifconfig, transcribed from the proxmox cmd line login on the physical hardware:

Cluster IP migration

March 24, 2014, 3:23 am

Hi,


I need to change IPs of both nodes of a 2 nodes (up to date) unicast cluster with no downtime of any VM. (old IPs: 88.x.x.x, new ones: 195.x.x.x)


I planned to:
- move all VMs from one node (B) to the other (A)
- change B IP
- migrate back all VMs from A to B
- change A IP
- dispatch VMs like they were at the beginning


So far so good, I tried the following:
- move all VMs from node B to node A
- change IP of node B in
/etc/network/interfaces
/etc/hosts
also change /etc/hosts in node A
- /etc/init.d/networking restart (node B)


this led to node B glowing red in the cluster, and no VM migration possible.


- reboot node B


not better


- restore previous network config in the previously changed files
- /etc/init.d/networking restart (node B)


cluster still down


- reboot node B


cluster finally restored, back to start.


Since the new IPs are in different ranges than the old ones, I’m not sure if I have any chance to make a temporary cluster with node A in the old range and node B in the new one.


Removing node B from the cluster, moving IPs of both nodes and setting again node B in the cluster doesn’t feel that safe, according to:
http://pve.proxmox.com/wiki/Proxmox_...a_cluster_node


What is the safest way to operate this migration?

Adding another disk and changing boot order on it fix the issue but need copy file and reinstall all program (windows vm)
So it's not a config issue, it's a problem on the VM disk.
I use RAW disk. Happen already 3 times.

How i can debug it for find where the problem happen ?

Proxmox Two-Node High Availability cluster problems with Quorum Disk

March 24, 2014, 9:32 am

Hi All,


I have managed to configure the Two node cluster and assign a Quorum disk to a Third server using an iscsi target.


In the work-through outlined in:- http://forum.proxmox.com/threads/163...ive-migrations


The iscsaidm example for connecting to the iscsi target is not persistent and does not survive a reboot on either of the Proxmox Cluster Nodes.



I therefore decided to set-up the iscsi target in Proxmox storage assigning it to both nodes.



After a reboot the primary node can see the Quorum disk and a clustat shows the Quorum disk.



However on the Secondary node the Quorum check fails on boot.



If I run /etc/init.d/cman reload on the secondary node I can then see the Quorum Disk when using clustat.



It therefore looks like the iscsi target is mounted after Proxmox checks for the Quorum disk on boot.



The Quorum disk is mounted on the primary server before it checks for it.



Is this problem due to the way Proxmox starts clustering?



How do I mount the Quorum disk before Proxmox checks for it on each node?



Will adding iscsiadm -m node -T iqn.BLAHBLAH -p IPOFiSCSISERVER -l to the /etc/rc.local work?



Are there any benefits in running more than one Quorum disk on a two node Cluster?

This link tells you how to set-up a 2 node Proxmox High Availability cluster using DRBD (for network based RAID 1 replicated storage in Primary/Primary mode over LVM)


I've always been a bit wary of using DRBD after a few problems with split brain.


Now with the launch of Proxmox 3.2 we have the ability to use Ceph storage.



Can we use Ceph on just two nodes?


If so, has anyone tried this and can offer some inputs?

cloning a KVM?

Coming from Xen/VMWare, cloning, templating, and booting up a live VM in seconds are one of those features that makes virtualization wonderful but I do not see it supported on Proxmox(?).

Or am I overlooking something or is there some reason proxmox don't support this?
I know you can manually do some workarounds via CLI, boot it up and change the IP, etc, but why not be able to do it from GUI?

Lack of this feature makes it a bit tough sell to customers, because currently they have to buy a VM, and they have to install OS from scratch via the VNC? Using Hostbill btw.

OTOH, the Openvz is not a problem and I wish KVM worked in similar fashion where you can boot up a fresh image in seconds.

But please correct me if I'm wrong ...
