OK Luckily, I found an old backup and copied "ceph-vs5" folders of "/var/lib/ceph/mon/" & "/var/lib/ceph/mgr/" to the server, rebooted the server. After that manager worked but monitor not worked. Becuse there is its folder inside /lib/mon I could destroy the monitor an recreate it again. Now...

Hi, I have 3 nodes. Today I updated 1 node: pve-kernel 6.4.-15 to 6.4-18, pve-manager 6.4-14 to 6.4.-15. There was no ceph update at this time. I checked the ceph to validate the status before update other servers. Ceph seems working but the updated node failed the its own monitor and manager...

yes, time is get by ntp server and it looks like it is working main storage is ceph iscsi target is defined on 2 nodes only. infact this node is a low profile machine, there may be some hardware issues also, for example this machine comes to online in almost 12-13 minutes after reboot. Frankly...

I checked the node with "systemctl status pve*", i am getting: ----------------- pve-firewall.service - Proxmox VE firewall Loaded: loaded (/lib/systemd/system/pve-firewall.service; enabled; vendor preset: enabled) Active: failed (Result: timeout) since Mon 2022-03-14 17:06:28 +03; 1 day...

I checked the mtu sizes of all interfaces of all nodes. They are all same and set to 1500. My switches dont have mtu change option, there is only jumbo frame support but it is disabled.

I attached last syslog of vs5, I had done several reboots. I hope it helps.

Thanks Moayad, These restarts resolved the status. But when i reboot i have to run them again.

Hi, I have a 3 node cluster. Last saturday I updated them all. After upgrade (not immediatelly, at saturday night i think), one machine went into status unknown. That machine and its drives-vms are shown as unknown status. However, I can access to the server, and ssh it. Ceph shows there is no...

Thanks your feedback Stoiko, sorry for my late reply, i wanted to dig it more before. I tried many things, and dealt with the logs. Unfortunatelly the best i could get via -moving disk from ceph to local -removing HIDS/NIDS plugins -increasing the core number from 3 to 6 :)) most recent updates...

Hi, I installed alienvault ossim on my proxmox cluster as a siem solution of my network. Infact I guess this question can be more related with ossim itself than proxmox, but i would like to know your experience. Running proxmox machine has 2x4-core xeon e5410 with 16gb ram. Ossim uses 3 cores...

No, it should be dynamic so that it can be set by vm itself according to carp protocol, afaik

Hi, I installed a vm for Opnsense backup firewall. Master firewall is a real machine. For carp communication, it is suggested to enable mac address spoofing for VM. ( https://www.thomas-krenn.com/en/wiki/OPNsense_HA_Cluster_configuration ) But i couldnt find a way to enable mac address spoofing...

Thanks Aaron, Since I use ceph to host VM disks, is it important to use a dedicated migration network? If i am not wrong, dedicated migration network is not necessary if guest is offline. But what if guest is online, does it have a big data to migrate which we will prefer a dedicated link for...

Hi, Sorry if there is an answer before. You know, we may have lots of physical servers for virtualization, and this means that there will be so many roles in them. Consequently each server may have multiple nics. I know, this question really depends on what is needed but i am seeking general...
