    [SOLVED] Can't remove nodes, cfs-locked 'file-replication_cfg' operation: no quorum!

    I've got a PVE 6.2-10 cluster with 3 nodes. It's using local ZFS with storage replication between nodes. A number of things are changing in the environment, so I need to break the cluster apart and run everything on the 1 node. I moved everything to node 1. I then turned off nodes 2 and 3. At...

    Backups are not using dirty-bitmap like I thought

    I have PBS running as a VM on node 1 of my 3 node Proxmox Cluster. I setup a backup job within PVE to backup my running VMs everyday at 1:30. The backup occurs but inspection of the logs it appears to be reading all blocks and not using dirty-bitmap. I'm at a lose as to why. I've tested...

    inter-VM traffic on same node

    I'm curious, does Proxmox have default mechanisms that route traffic between VMs and containers that reside on the same host without the traffic leaving the host to a physical switch? Basically a virtual switch. And if so are there limitations on the speed? Doing some quick iperf3 tests seems...

    Backup Repo ZFS record size considerations?

    I'm not totally up to speed of how PBS functions. But I noticed that ZFS seems to be the preferred repository to use and was wondering if a specific record size or other tweaks should be considered when used in this case to combat fragmentation or write amplification. From what I understand...

    External Authentication?

    I thought I read that PBS will have external Authentication (AD/LDAP) like PVE has. Is that accurate? How about the 2FA functionality as well? I installed the beta and didn't see it there yet. Thanks.

    pipe vma extract

    I'm working on something and was wondering if vma extract output can be piped. Right now I'm looking at piping to rsync (that could change later). Thanks.

    Boot & VM data on same zpool or seperate?

    Hello, I'm wondering what the proxmox teams recommendations are for ZFS. I see proxmox now support UEFI boot and supposedly rpool supports all ZFS feature flags in this configuration. During installation of Proxmox the "rpool" is generated. The ROOT is there for booting. And rpool/data is...

    fsync performance oddities?

    I have 3 different nodes that I'm messing with. All 3 nodes are the same (servers, CPU, RAM, HBAs, etc), Intel R2224GZ4GC4 (barebones) Intel S2600GZ (motherboard) Intel E5-2670 x 2 (CPUs) Hynix HMT31GR7CFR4A-H9 (8GB x 16) (RAM) LSI 9340-8i (SAS3008 flashed to IT mode) They all use ZFS. Was...

    chroot inside LXC container?

    I spun up an LXC of CentOS7 and walked through the installation of packetfence (NAC). I got to the point on setup where it wants to connect to active directory and just haven't had any luck and I'm not even getting anything useful in logs. So I started researching a bit and found THIS. Which...

    ZFS cli live migration

    I've got a 2 node test enviroment (would be 3 but that node is in use right now). I was testing the replication and migration capabilities in the latest proxmox release using local ZFS storage. Reading the forums I found out that LIVE migration doesn't work right now UNLESS you turn off...

    ZFS boot failure (GRUB issue)

    I performed a proxmox install and selected 2 disks (out of 17 available disks) for a RAID1 install. After reboot it doesn't boot and I just get a black screen with a cursor. This seems to be a grub boot problem. Hardware Intel R2224GZ4GC4 Intel S2600GZ Intel E5-2670 x 2 Hynix HMT31GR7CFR4A-H9...
