  1. How to back up a folder only

    Hello there! I'm currently in the process of planning out a system for a new setup I'm working on. This will, of course, include PVE to be the host of some Windows VMs and other smaller stuff. Also, I want to host some sort of NAS (samba-only is enough) from that same host/server machine. So...
  2. LDAP Sync with nested Groups

    Hello everyone, I am currently trying to implement LDAP Sync for our Proxmox cluster. Basically it's working fine, the only thing I don't get to sync are the user to group associations when a user is in a nested group. This is the relevant content of my domains.cfg: ad: example.local...
  3. [SOLVED] After syncing to a new datastore: backup owner check failed (pve-user@pbs != backup@pam)

    Hi, I wanted to switch to a new datastore (store02) (on different disks) so did the following: Add a second datastore to the pbs server (store02) Added a remote with localhost and the store02 datastore Ran a sync from store01 to the "remote" localhost:store02 Removed store01 Modified the...
  4. Sync issues after Lets Encrypt Renewal

    Hi all, I have an issue where whenever my 2 node PMG cluster renews the certificates the cluster stops syncing. On the master I get this: pmgcm status NAME(CID)--------------IPADDRESS----ROLE-STATE---------UPTIME---LOAD----MEM---DISK swarmx1(1) 192.168.11.218 master A 44 days...
  5. Cluster update (kernel no longer match)

    HI all, I am hoping you can help me with an issue I am having. First... sorry if this is posted elsewhere. I tried to do my research. I did updates to my 3 node cluster the other day and now the Monitor version are not the same and the kernel is not the same on just one of the server (all 3...
  6. Strange disk caching mode results and questions

    I have been testing my VM disk performance on an NFS synchronous shared storage. The results have left me scratching my head trying to figure out whats going on. The results may be the expected behavior, but even so I am lost how that may be. On my NFS synchronous share I created a VM (Linux...
  7. LXC on NFS (sync) does not work

    I am mounting several NFS shares. For my LXC and QEMU images I wish to mount the NFS share as synchronous. QEMU guests are working well on the NFS sync share. For LXC, however, I noticed my sync writes dropped down below 10 MB/s and would hang for several minutes after writing test files. The...
  8. Templates folder sync between master and nodes

    Hello, I have create the /etc/pmg/templates folder. This folder is sync between master and nodes everything works fine. But if I create some file with postmap command this file is not synced to the nodes, why? I think the rsync(?) between master and nodes exclude .db file which was create with...

    ZFS snapshots and replication: Sufficient as backup?

    Hi all, We are currently running a PVE cluster with multiple machines and serve about 15 LXC containers and 10 VMs. We are using PVE replication (every 15min) to onsite PVE machines and znapzend to create hourly snapshots that are also replicated off site. This should protect us against a...
  10. Swap sync set to always by default?

    Ever trying to gain just another percent of performance out of an admittedly sub-par setup, I have arrived at the sync parameter of zfs. Digging through some boards told me that disabling sync should be kinda-sorta ok if I trust my power supply, the data on the servers is well backed up and a...
  11. LDAP user sync

    Hi forum, AFAIK I need to create all LDAP users manually in Proxmox as well. That is - in my eyes - a bit weird, cause LDAP should be the central point of user management. If I have to manually mirror the users I really don't get the point of the whole thing (actually, I find it kind of...
  12. Proxmox 5.1 remote backup

    Hi, I am currently running several VMs in a node with SATA disks with Proxmox 4.4. I have purchased two servers, one with SSD drives and another one with SATA drives, both running 5.1. The idea is to split some VMs between those two nodes. I am planning to run 2 VMs on the server with...
  13. Proxmox NFS storage performance and async

    I have a NFS server and Proxmox 4.4 node over 1Gbit LAN connection. When using async the performance is really great, but unsafe? Or what is the best practice to increase the performance against sync? With sync: /etc/exports: /var/lib/vz/nfs/vm 192.168.123.0/24(rw,sync,no_subtree_check)...

  15. ZFS dedicated SLOG

    Hi, I'm trying to find if my proxmox system (with ZFS) will benefit from adding dedicated SSD M.2 for the SLOG. So can I somehow profile my system and find the number of sync writes (O_SYNC), or better, find if my sync writes are bottlenecks? I don't want to benchmark, I want to get the info on...
  16. drbd inconsistancy issues

    Hello, I'm using drbd9 on a 3 nodes proxmox4 cluster and wanted to change one of my disks. I've detached ressources on the old disk then remove the node, changed the disk, add the node and reassign resources. I have two issue, the first one is that i have no space left on on the other nodes...
