Hi, thanks for your reply. I can tell for sure that nobody had directly modified that file... and neither had I, of course. Anyway, when I was installing the server, I restored that vm from backup on the SAS storage and then moved the 50GB disk to SSD storage through UI -> Move disk .. no...

Hello everybody, At the beginning of this week, I just deployed a new PVE 4.4-13 cluster over a DELL VRTX with 3 blades with HA active for almost every VMs, and everything was working flawlessly. Storage is LVM, of course. Just one hour ago, for some unknown reason, one (or more? I didn't get...

So it seems that the overall Ceph performance is not that great as one may think... I mean: can I compare eg. 3-node ceph cluster with 2 osd (15k SAS 600gb) + 1 jornaling ssd per each node against a dedicated FC/iSCSI SAN with the same amount and kind of disks? I think the SAN would win here in...

hi melanxolik, thanks for sharing. I don't have a specific workload, but just need to get an idea on how to dimensionate a pve + ceph cluster in a scalable way. A common environment could be ~10 vms (domain controllers, smb file servers, mail servers and database servers (oracle, mysql), web...

Hello, could you share your working and tested configuration (DELL anyone?) for use with Ceph? I need a 3-nodes general purpose configuration which offers good performance (~10-20 vms). Details are welcome (hdd/ssd models, benchmarks, problems encountered.... and so on). In addition I have a...

Hi there, I had to create a samba server with shadow copy support, so I needed a fs with snapshot support and I thought to use BTRFS which is well suitable for this purpose (I used it before on bare-metal installations). Since it's a COW filesystem like ZFS, I was wondering if it could cause...

Hi fireon, Glad to hear so.. I'll appreciate a lot if you would like to share your work, and I think it's not a problem if your docs are in german. Google translate is my friend :) Thanks, Michele

Was my idea really so bad ?? :(

Hello everybody, I'm looking for a reliable way to backup ZFS zvols of my proxmox system. Since the built-in vzdump tool is pretty slow, as it always create full dumps of each virtual disk wasting a lot of disk space (no plans for qemu incremental backups yet? -...

Proxmox 4.0 is out. Are there any improvements with backups (eg. incremental) ? I'm still looking for a reliable solution which allows to perform VMs' disk images without requiring an agent installed on each, and which supports incremental/differential tasks as well, in order to save storage...

I agree with you, but where do you store backups? I guess you need another machine with ZFS where you run zfs receive.

Sincerely, I had no issues when I tried to access to the web interface on the other nodes when the primary (where I created the cluster) was down.

If the proxmox node1 suddenly dies (few months after my other two nodes have been powered off) ... I won't have /etc/pve replicated .... that could be an issue ? Maybe I could schedule an rsync ... ?

Yes, I tested all the possible combinations and I've been able to migrate and create new vms all the times

I have obtained the same result using qdisk, but with less effort :D I installed proxmox on 3 VMs (the nodes) where I attached a small 1GB iSCSI disk from my NAS Then, I created a partition on it and formatted as qdisk: # mkqdisk -c /dev/sda1 -l qdisk01 Writing new quorum disk label 'qdisk01'...

Hi, thanks for your reply. So, basically, your idea is to use another proxmox VM inside the main node, acting as fake node to increase the votes count. Am I right? What about using quorum disks instead?

Nobody helps? :(

Hello everybody, Currently, I've got a proxmox node with fiber channel SAN storage (I'm using LVM here) and NFS on a Synology NAS. Since I've got another two smaller spare servers available, I would like to put a FC HBA card on them and create a 3-node cluster, but I don't want to keep these...

Hello, I finally found the cause of the issue! I just disabled scheduled backups of the two VMs, and the host stayed up for 2 weeks without interruptions. Now, I'm looking for an alternative solution to vzdump+lzo backups .... :rolleyes:
