    Bug involving namespaces and .chunks directory?

    I have two datastores for PBS: a 4x2 raid10 (ZFS) and a ZFS mirror. GC for the latter works just fine. For the former, every time it runs, in phase 1 (marking), I see: found (and marked) 602 index files outside of expected directory scheme. (602 is the total number of chunks)...

    Curious about 'localhost' for a ceph cluster

    So I have three nodes, pve1, pve2 and pve3. Because I started off with pve1, the mon is called 'mon.localhost' and the manager is also 'localhost'. I'm assuming this is all OK, but it looks weird to see mons localhost, pve2 and pve3, as well as managers with the same naming convention. I also...

    Problem with live migration?

    Running a new install of 7.2, upgraded to 7.3. Guests live on a ceph/rbd datastore. I've noticed a couple of times when doing a live migration, that the guest seems to be migrated succesfully, but then fails to be up and running on the target host. Log snippet: 2022-12-05 09:40:36 migration...

    Is it possible to have a hotplug datastore?

    Migrating off vsphere. My backup strategy had been: daily, weekly and monthly to a ZFS raid10 using veeam. 1st of each month, I'd hotplug a 1TB SSD and run a manual veeam job, scrub the hotplug pool, export it, and shelf it safely. Is there any way to do that with PBS? I've got a datastore...

    What is the difference between spam and junk messages?

    e.g. in the Proxmox Status Report? I've looked through the docs, and if it's there, I missed it...

    Two nodes connecting to iSCSI shared storage with different IP addresses?

    I currently have shared storage on a omnios ZFS appliance via NFS. This uses a 10gb enet interface. I have a second host in the cluster which is normally off (it is a smaller, older host.) Literally only used to migrate guests to while doing maintenance on the primary host. Currently I need...

    Best way to disable cluster services?

    I have my one big server with NVME for the guests. Works great. Sometimes an update is pushed by proxmox which requires a reboot. So I have an (older) sandybridge server which I added to the cluster. I migrate all the storage to NFS, then all the guests to the other node. Upgrade & reboot...

    Is there a way to convert from non-zfs root to zfs root?

    It isn't a big deal, but when I did the initial 4.4 install, I used two SSD on an old LSI RAID controller. I'd like to migrate the install to a ZFS mirror. If there is no good way to do that without a reinstall, I'm fine with leaving it the way it is. Thanks!

    zpool failed to import on reboot

    SATA raid1 and NVME raid1. Rebooted. NVME pool not present. Imported manually and all was well. Looked at /var/log/syslog and saw this: May 1 17:23:20 pve zpool[1036]: internal error: Value too large for defined data type May 1 17:23:20 pve systemd[1]: zfs-import-cache.service: main...

    unable to online migrate to host with local ZFS

    I have two hosts, one has a zfs raid1 with two NVME drives. They are both connected to a JBOD via NFS. To upgrade the first host, I did this: move all disks from nvme pool to jbod (shared) pool migrate all guests from host1 to host2 upgrade and reboot host1. Unfortunately, if I try to...

    Backup hangs after 'creating archive ...' ?

    Proxmox 4.4. I have a Windows Server 2012 R2 VM cloned from a newly created template. It is on a ZFS storage. If I try to back it up, it proceeds to the step where it says 'INFO: creating archive ...', and then sits there. If I stop it, it seems to leave the VM locked, as I can't do anything...

    How does vzdump+snapshot work with zfs storage?

    So I created a storage of type 'ZFS'. I have confirmed that virtual disks created there (raw or qcow2) are being created as zvols. If I manually take a snapshot of such a guest, it creates a ZFS snapshot on that zvol. That makes sense. If I then back up this guest, and specify 'snapshot'...

    Proxmox 4.4 performance with ZFS+NVME

    So I got a couple of Samsung 1TB 960 PRO drives. I tried to use them with ESXi and Xenserver, but performance in both cases sucked. I had created a simple mirror using them. In both cases, I tried using a virtual storage appliance and exporting the ZFS datastore via iSCSI or NFS. I was lucky...

    Installing with misbehaving display?

    I'm trying to install proxmox 3.4 on a host with a supermicro motherboard, with builtin VGA. It comes up to the splash screen with only a small part of the license screen showing. The Abort button is visible towards the bottom of the screen, but the 'I agree' is apparently off to the right, so...

    How to grant non-root users privileges to do most things?

    Okay, forgive me if this is a silly question, but I've googled and looked at the online help, and came up empty. When I have used proxmox before, I just used root. I need to deploy a server with proxmox for me and two other people to use. I created the unix accounts for them with passwords...

    Proxmox HA - is this possible?

    My current setup: two hosts running vmware in 2-node HA. A third node running Centos 7 as a NAS (exporting storage to the vmware hosts.) I wanted storage redundancy, so there are virtual centos guests on each vmware host. The storage is on an SAS JBOD with 2 inputs - one to the physical...

    Sheepdog users out there?

    Based on a couple of articles I read, I decided to dabble with this. It was certainly simpler than setting up drbd, I'll say that much! Took about 5 minutes and I had a centos guest up and running. Write performance (two nodes with --copies=2) was about wire speed (110MB/sec). A large...

    Snapshotting guests on shared replicated storage?

    So I am running two PE2.3 hosts in a cluster using drbd as shared local storage. Works perfectly. My only complaint is that I can't snapshot any of the guests, since the storage is not snappable (lvs on the vg on top of the drbd devices.) What is frustrating is that since the storage is...

    Online migration failure - no useful info?

    I have a running ubuntu 12.04 guest on proxmox2. I am trying to migrate it to proxmox1. It has no local resources or anything. I fire up the migrate (same results from cli as gui) and see this: root@proxmox2:/var/log# qm migrate 100 proxmox1 --online Apr 04 09:49:12 starting migration of VM...

    Odd failure when restoring a backup to an LVM on block storage?

    I have a number of VMs with raw disk files on an NFS datastore. I created drbd mirror to other host in proxmox cluster. Put LVM on top of that with shared set to true. This way, as I understand it, each vm disk is an LVM. Anyway, all but two restored just fine (e.g. I did backup from NFS raw...
