is there a way to set a refresh time ? (we 're using PMG with action to reject user when not in LDAP user ) The question is when and how to set up this ? It gave me some : 550: 5.1.1 <xxxx@domain.com>: Recipient address rejected: undeliverable address: Recipient address lookup failed...

thank for your answer , but with this method you need twice the capacity of your original zpool ??? (a thing you can't do with one server)

before doing that ... and choosing ZFS (actually RAIDZ2 4 * 1 TB) as file system for my cluster ... i'm really afraid of scalability of ZFS ! i've been working since two year with Ceph (it's very scalable, anb easy to manage : thanks proxmox !!!), i'm trying ZFs (ceph perf. are not very good...

i can acces the server now but i will answer asap, thank you for your help.

Can we really REALLY know which hard drive is used or not by promox, linux and ZFS ? root@node2:~# ls -lah /dev/disk/by-id total 0 drwxr-xr-x 2 root root 940 May 6 23:42 . drwxr-xr-x 8 root root 160 May 6 23:32 .. lrwxrwxrwx 1 root root 9 May 6 23:32...

i'm on the same problem , this is really awfull and painfull to manage ! Disk are /dev/sdx But promox use /dev/disk/by-id ... And zfs use another label .... another idea for adding another layer ? KISS ? root@tankster2:~# zpool status zPool1 pool: zPool1 state: DEGRADED status: One or more...

Is this type of config supported by promox ? (host management on VLAN)

Is it possible to do that with WEBGUI ? because if i do what it is in the wiki, it gave me a Type : unknow. But VLAN is working perfectly. But i can't access VM or CT console : Why ? is it normal ? i need to isolate proxmox hypervisor from CT, VM (user network) mut not see hypervisor etc (we...

in fact i would like to compltely isolate proxmox ve admin network (the only one that can have a gateway ;-)) from user network (pct + vm) , user network go through hardware firewall with one nic , proxmox admin network another one..

must i deploy firewall VM (or lxc) on each Node of the cluster in order to isolate lxc each other ? (like in docker) or pve provide tools for doing that ?

thank you for those answsers. But can docker ,use of /dev/rdb1 (ceph ) device manage by proxmox , is good or not ?

ok, baremetal + promox + VM + docker But why not : baremetal + promox + docker ? What about performance with VM layer ? thank you

LXc are good (debian ok, but with centos image ... some issue). Do you planned the containerd , docker integration as for lxc in proxmox VE WebGUI ?

up

thkx alwin, i already read this doc. BUT : When ceph and pve are on the same hardware (server) , with 3 nodes : what is the mean of Public network and Cluster network ? Where datas are passing throught ? (really)

ouchchhhh : i will give it a try , it's seem to be the answer ! For those answers

hello aaron, thank you for replying. ok for native linux switch , and go for 128PG (default infact) you read wrong : ceph is on top of LACP (bond) 4 Gbit not 4Gb ( 4 gbit give me 4 x 125MB/s ... 500MB/s for HDD , i think it's enough !!) , and i don't have money for 10Gb switch nor 10Gb nic ...

Is it a good setup, 3 questions ... First we have 9 gigabit NIC per node (3 nodes, cluster pve) , is it good for production ? (OSD are 1TB HDD 7200tr/mn, for all we have 18 OSD : is 256 pg is enough or must we stay on 128 ?) - 1 cluster corosync, migration, webgui (pve node) ...

... i do a test with [6 CT simultanously doing a dd if= ...] : it seems that Ceph does not use all 3 Gigabit link (but 2 ...) : i can add all bandwith , 174MB/s (177 IOPS writes)
