2. ZFS would still be my choice, but with the limited RAM you have, you would definitely need to MAX your ARC size, because it could take up to 50% of your RAM. Otherwise MD-RAID is one way to go.
3. Both is possible. I'm a fan of having my block devices only in the Proxmox host itself...
I do not think that this is a security issue as long as access on the proxmox nodes is restricted.
Anyway, i don't know which provider you have, but the switch at the WAN side should only send packages through onr port anyway.
Anyone else: If i'm missing something here, feel free to correct me.
Ich hab das selbe Problem. Mit beiden meiner Microserver Gen10 Kisten.Sowohl mit Proxmox Backup Server als auch mit Proxmox VE.
Ich gehe daher mal von einem Kernel Problem aus und habe dazu einen englischen Thread eröffnet...
i'm kind of lost here.
I'm having the same issue as described here in the german thread: https://forum.proxmox.com/threads/reboot-problem-hp-microserver-gen-10.100508/
Just as a side information:
I've had PBS running for a while on an HPe Microserver now. Last Week Friday i...
Can't u just setup a VM on your proxmox host with proxmox backup server and use the cifs share as a datastore? That'd solve the issue. I'm doing that with a synology HA setup at a clients place too. works fine.
Yes, that is correct. It limits I/O bandwidth.
Do you use a seperated Network (VLAN?) for backups, or have the possibility to do so?
If so you could create a VLAN or another network, add the VLAN interface, or network interface to proxmox and limit the bandwidth with tc or wondershaper for...
Thanks @H4R0 for pointing out, i didn't catch that.
Seems like they're Seagate SAS Exos drives with 2.4TB.
I'm taking a guess here by saying, that those drives are usually pretty reliable, but even if a double disk failure is likely to occur
which would destroy the pool. A triple disk-failure...
