hello,
we have 3 nodes , with 10Gb card , and HDD.
Which control panel can you advice us for a webhoster (website mail , sftp, ssh , vps -- lcx ? , app template like softaculous) ?
(ispconfig, cloudmin , virtualmin ... ?)
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...
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...
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...
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 ?
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) ...
Here is my setup (newly buy)
3 node with x :
- bi xeon 3.2Ghz (16 x 2 core)
- 90 Go RAM
- 6 x 1 To HDD 7200 (ceph osd) + 2x 500 go hdd (ZFS RAID1 proxmox install)
- 5 x 1gigabit nic : ceph public (1 nic) and ceph private network (3 gigabit nic in lacp 2+3 , dedicated to ceph storage trafic on...

Hello,

Upgrade from pve 5 to 6 work flawlessly ... but now , ceph cluster perf. are just awfull .
Before 63 MB/s ... now 16 MB/s why ? (test with dd , as recommanded by ceph, under CT , CT IO are extremely slow now .... )
And with Debian stretch to buster migration...
Now we backup our LXc server (from one pull borg server) with sshFs remote mount file system, but for big server we need to stop mysql nginx etc , to be sure that we are file and app consistent for strategic data.
While using dedicated backup physical network : downtime is increasing :oops...
I'm near .... but :
#rbd snap ls cephPool1/vm-106-disk-0
