  1. [SOLVED] PVE/Ceph: Strategy for disaster recovery backups of VMs

    Hi there, we just started with our three node PVE/Ceph cluster - so far so good. Now I'm looking for the best way for "disaster recovery style" backups of our Windows and Linux VMs. At the moment we do backups like this: For file based backups we use Bareos which works well. For (weekly)...
  2. [SOLVED] command line tool for Broadcom SAS HBA 9300-8i

    Hi there, we have seven SSDs behind the HBA mentioned above. How can I find out the mapping between a physical slot and the disk inside Proxmox VE/Debian Buster? A long time ago I used storcli, but I can't find it anymore. Is this tool deprecated? Do you know other tools to handle this? Thanks...
  3. dedicated network for backup

    Hi there, is there a way to put the proxmox backup on a seperate network (interface)? At the moment it seems that it's going through the same network as the management GUi - and in our case this is just 1GBit/s, while there are 10 GBit/s possibilities waiting for work. :) Thanks and greets Stephan
  4. How to wipe a disk which was OSD before?

    Hi there, I did a reinstall of my three node PVE/Ceph cluster, and now I would like to clean up the OSDs so that I can use them again as... OSDs :D. Lately I found a nice command for this task, but I can't find it anymore. Can you help? Thanks and greets Stephan
  5. new three node PVE+Ceph cluster

    Hi everybody, we just decided to build a new virtualization environment based on three PVE+Ceph nodes. At the moment we're running about 50 VMs (Windows and Linux servers) which have assigned 192 vCPU cores, 377 GB RAM and 12 TB allocated storage, of which 8,3 TB are really in use. We like to...
  6. [SOLVED] PVE+Ceph cluster vs. cold standby solution

    Hi there, our about 50 server VMs are looking for a new home! The current usage of resources goes like this: 192 vCPU cores (real usage on the two nodes is about 15-20%), 377 GB vRAM, 12 TB vDisk (assigned), 8,3 TB (used). The load profile is a mix of everything: databases, mail, file and a lot...
  7. Filtering the Tracking Center output

    Hi there, I would like to know how to handle the "Filter" field in Tracking Center. For example, I would like to see all mails where the sender matches a certain toplevel domain. Is that possible? Is there any documentation about this topic? Thanks a lot for your support and many greets Stephan
  8. [SOLVED] Upgrade from v4 to v5: Greylisting database?

    Hi, when I do a migration like the one described in your video tutorial, will the greylisting database be included? If not: Is there a way to migrate the greylisting database? Thanks and greets Stephan
  9. [SOLVED] Ceph: Dedicated Journal Disks?

    Hi there, for better understanding I have the following questions about (dedicated) journal disks: When my OSDs are fast (for example 4x Samsung 1,92TB PM863a per node): Does it make sense using a (slower) 240GB PM863a as a dedicated journal disk for these four OSDs? Or would it be better to...
  10. Three node Ceph cluster: physical switching vs. full mesh network

    Hi, I just learned from here that it's possible to connect the nodes of a Ceph cluster directly to each other. I wonder if that would increase the I/O performance of the cluster, because there are no physical switches in between. For our upcoming project both (physical switching and a full...
  11. three node Proxmox/Ceph solution

    Hi there, it's not a real project (yet), but I would love to build a three node Proxmox/Ceph cluster in my mind and share the design ideas with you to hear your opinion about it. Here are the requirements: About 50 server VMs (full virtualization) - most of them windows servers, but also a...
  12. Is DRBD9 production ready?

    Hi everybody, when I take a look at Linbit's website I get the impression of a finally released stable piece of software, which is of course production ready: http://www.linbit.com/en/p/products/drbd9 But when I'm cruising through several forums, blogs, etc. I sometimes read that it's not...
  13. [SOLVED] Network performance between VMs

    Hi guys, no problem, "just" for understanding: When I create two little Linux-VMs (KVM, virtio NICs) inside a single Proxmox node and do some iperf between these VMs: What is the "expected" netwerk performance and whereof it is dependant? I just did two tests on two different pieces of...
  14. [SOLVED] PVE 4.2 & DRBD9: "Error: Operation not allowed on satellite node"

    Hi everyone, I try to build a two node PVE+DRBD9 cluster. Following this tutorial works fine - till the moment I try to add the second node to the DRBD cluster: # drbdmanage add-node -q srvpvedrbd2 172.16.190.32 Operation completed successfully Operation completed successfully Executing join...
  15. "Best practise" for a two node proxmox/storage cluster

    Hi everybody, yes, I know - the recommendation is using at least three nodes building a safe virtualization/storage cluster. But please keep in mind that there is software out there which you have to pay per node. At the moment we are running a two node cluster (RHEV+DRBD), and switching to a...
  16. Performance trouble with VM during backup

    Hi everybody, for testing purposes I built up a fresh PVE node using the current ISO image. Then I created a ZFS pool (zfspool1, 4 SSDs) for disk images. One further SSD acts as a local backup storage - an XFS formatted partition is mounted to /backup and connected via "directory storage" to...
  17. [SOLVED] once again: Poor FSYNCS/SECOND with mdadm/LVM

    Hi, my hardware is: - HP ProLiant DL370 G6 with 24x 2,5" hot swap bays (3 backplanes) - these backplanes are connected to an HP SAS Expander Card - the Expander Card is connected to an Avago SAS 9211-8i HBA - 22x HP SAS HDDs (300 GB, 10k rpm) - these HDDs are organized as a raid10 via mdadm...
  18. [SOLVED] pveperf for mdraid/LVM

    Hi, I configured a software-RAID /dev/md1 and gave it via LVM up to my Proxmox. Is there a way to do pveperf on this storage? Thanks and greets Stephan
  19. PVE, synchronous storage and a VDI infrastructure on two physical machines

    Hi everybody, our company tinkers with the idea of taking our about 55 client PCs (Windows XP at the moment, and Windows 7 very soon) into some kind of virtual desktop infrastructure. Since about three years we do server virtualization with VMware ESX as hypervisor and DataCore SAN-Synphomy-V...
