just a quick note although since day one it never changed but I cant recall if firewall was on when setup but current firewall state is on on each node. shall I turn off? although im not sure the behaviour of proxmox when things go wrong in ceph? does it shutdown and turn off or turn on things as precaution?? its been few days since the drive failure so Im not sure what proxmox would do in case of drive failure?
 
Well, maybe a simple INPUT - > ACCEPT might already do some difference, if the firewall rules weren't correct.
 
Here is my latest update, due to the fact im remotely connected and not on site it took me longer time to find out one of the actual ethernet cables for bonding was blinking orange and I recall it was green, this gave me an insight that on port isnt working as it used to be, I have asked them to replace the cable for that port and they did.
the server started going up and down for few minutes but ceph started to re adjust itself and the current reading is

which is fine for now. I will need to find out whats the reason for this sudden change.
but anyway we are alive and surviving again.
thanks alot for the help guys. we have learned a valuable lesson on this.
so always it will be helpful looking at syslog to check what is going on the background.
keep in mind it was pinging normal just the speed was low

This OSD is already near full and all in all there is not much space to redistribute. Delete data or add more OSDs. Otherwise you will sooner than later get into similar situation again.

Good that it works. It might just have been an issue on the switch. You never know.
