  1. External Ceph Monitor

    Hey guys we are getting ready to roll out a new production ceph cluster using proxmox. I wanted to get some input on monitors. Does everyone always use external monitors, or do most use their OSD nodes? I want to have 3 monitors, but was thinking of maybe 1-2 external monitors and 1 monitor...
  2. Ceph Issues

    I managed to totally mess up my ceph cluster. Is there any possible way to start ceph from scratch but re-use the OSD's and preserve the data?
  3. Odd network issue after upgrade to Proxmox6.2

    4 node cluster of 2x HP DL 560's, 1x HP DL 380, 1x Supermicro and Nimble storage. This cluster was on 5.x for a couple years now with no issues. The issue only exists on one of the four nodes. Along with that the issue seems to only exist for the VM. At random times the VM looses network...
  4. IGD Passthrough setup broke with Proxmox 6.2

    I had a 6 setups update to 6.2 last night that are having some issues booting a VM with IGD passthrough. Here is what I get with the first boot of the VM. kvm: -device vfio-pci,host=00:02.0,addr=0x18,x-vga=on,x-igd-opregion=on: vfio 0000:00:02.0: failed to open /dev/vfio/1: No such file or...
  5. Ceph Nautilus Issues

    This started off as a Luminous cluster on 5.4 (Which was rock solid and we never had any issues). About a month ago I moved it to 6.1.8/Nautilus and my monitors have started giving me a ton of problems. Hoping for a bit of help as I am not sure what I can do. Sometimes on node reboots I...
  6. [SOLVED] Ceph Luminous to Nautilus Issues

    Hey all I just updated my 6 node cluster from Luminous to Nautilus. Overall it went well except on one node. Looks like the /etc/ceph/osd/ directory is totally gone which seems to be the main issue. Any ideas on where this could have gone in the upgrade process? I am thinking my only...
  7. Ceph Octopus

    Does anyone know when this might hit the streets/proxmox?
  8. Proxmox6 VM backup causes Windows VM to lockup

    Hey guys we recently started moving our production clusters to proxmox6. Everything has been going really well except for when we backup our 1 and only Windows Server 2012 VM. It causes this VM to lockup and we have to reset it via the proxmox GUI. All of our linux VM's and Windows 10 VM's...
  9. Proxmox5 -> Proxmox6 Automation

    I am in the process of trying to automate Proxmox5 to Proxmox6 as much as possible for some simple 1 node setups out in the field. I am able to automate most of the apt-get aspect using something like this. DEBIAN_FRONTEND=noninteractive \ apt-get \ -o Dpkg::Options::=--force-confnew \...
  10. Any other causes of a graceful reboot?

    One of our clients systems (3 node Proxmox 5.1) gracefully rebooted yesterday mid day and we aren't quite sure why. Its a HP DL 380 Gen10 that has been in place for a bit over 6 months. Am I correct in thinking that the watchdog would never do a graceful restart? In the logs we saw the VM...
  11. ZFS Boot mirror M2

    Can proxmox be installed into 2x M2 SSD's with ZFS mirror? I know this was a issue in the past, but I haven't seen much more on it.
  12. Proxmox Supporting Ceph

    I know proxmox supports Ceph pretty extensively. We are looking to move our production over to ceph and wouldn't mind having some solid 3rd party support. Proxmox support has been good to me in the past and I was wondering if that is enough or if we should consider a 3rd party option? I am...
  13. New All flash Ceph Cluster

    We are looking to build out a all flash ceph cluster and I wanted to get some opinions. We would use proxmox with enterprise subscriptions. This cluster would be dedicated to ceph with no VM's. Leaning towards a 8 node setup using the supermicro 2113S-WTRT as the chassis with a AMD epyc cpu...
  14. Any Proxmox Ceph Users Interested in helping test Benji

    Hoping this doesn't cause any issues as far as the rules go. I have been testing this for well over 6 months now and its been really solid for a Ceph backup solution. https://github.com/elemental-lf/benji I backup my ceph rbd volumes every night via benji and the overall space usage is...
  15. Host Ran out of memory

    Hey guys we have a host with a single VM. The host has 1.48TiB of ram and we allocated 1.44TiB to the VM. We typically always leave 25-50G of free memory for the host. Based on the numbers above we should have a bit over 40G of memory always available for the host no matter what. Last night...
  16. What could cause this?

    Hey guys we did some site failover testing this past weekend. When bringing the clusters back up at our main site, we found that corosync would fail to start and the nodes wouldn't join the cluster. After lots of head banging, the only way we could get this corrected was to add a entry for...
  17. Zero out a ceph disk

    Is it possible to zero out a ceph disk? For example we write zero's to our iscsi storage to get our space back, or to help make the proxmox VM backups nice and tight. Would the same process of using dd on a ceph rbd device get the job done as well? I started to test this, but the object count...
  18. Interesting Realtek Speed Issue with PVE5

    We are running into a pretty interesting/odd realtek NIC speed issue on proxmox hosts. 01:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 0e) The only thing we use these hosts for are small CentOS7 VM's which act as...
  19. NUMA and 4 sockets

    Hey guys we just went live at a customer with our biggest server yet. DL 560 with 4 sockets and 1.5TB of ram. I believe we are running into some odd performance issues due to the way the memory is being spread out over the numa nodes. Here is how the host looks node 0 free: 2387 MB...
  20. Deleting Large LVM disks with 4.15.18-20-pve fails

    Hitting some odd issues with deleting larger LVM disks on 4.15.18-20-pve 5.4-13 . Our setup is HP DL 380 Gen10 front ends, nimble iscsi storage with LVM on top. Deleting VM disks over 2TB fails on 4.15.18-20-pve and causes the host to basically loose access to the storage. Only way to get...
