From what I read the reason the Ceph devs decided to disable Trim is they believe enterprise SSD's will do it internally, but consumer ones may not. I suspect it needs to 'catch up' now that you've enabled it. You may see odd spikes when it trims but it shouldn't be constant high latency.

Probably will do initially yes.

You may need the trim support given those are consumer SSD's

I suspect this won't be needed if you are using proper enterprise SSDs but if not you may need to enable trim I believe it's ceph config set global bdev_enable_discard true But I'm taking that from my very badly written notes on what I did on my test cluster so the command may not be correct...

Some years ago I abused a 500GB Samsung evo 850 consumer SSD as a caching drive in a small server, also using it for tmp storage when writing lxc backups. It's still going after 3yrs of power on hours (it's older than that it spent a while not doing much) and it also spent some time as a games...

So I have a Proxmox machine in a co-lo with a public range on vmbr0 (It's a single server co-lo so I don't have a router/firewall I control upstream) It's firewalled using the PVE firewall, configured under the datacenter tab and I've confirmed I cannot access the Proxmox UI.etc from an...

I have a Ceph cluster on extremely under powered USFF nodes at home to learn/experience ceph (Actually pleasantly surprised with how that's performing). Do you know what the overhead will be. System has 64GB ram at the moment, it may end up with more once it gets here and I see what the memory...

Would I be crazy to run Ceph on a single node? configured for OSD level redundancy (instead of host level). Was thinking of using Ceph as I can change the resiliency settings, or replace disks with larger ones and re-balance easier than if it was just a static ZFS. (This is assuming I can put...

can also be set per OSD Supposedly shouldn't be needed with modern enterprise drives Absolutely needed with crappy consumer drives like the ones found in my homelab ;-)

It seems since yesterday there's been a CEPH update, I just upgraded from 17.2.4 to 17.2.5 and now I seem to be able to write to the EC 2,1 volumes with a OSD offline. Edit: I think it was actually the lack of Trim and the state of some of my SSD's that was the problem and it working after...

So I'm playing around with Ceph in a lab setup on some extremely low-end hardware, and I was testing EC on a 3 node cluster. I had Proxmox installed on USB sticks as originally, I didn't realise the OSD can be a partition rather than the whole disk. I started removing/replacing OSD's so I...

For the Paid subscriptions how does the Socket count work, If I had some machines that have a 2S motherboard but only one CPU installed (I.e the 2nd socket is empty) Do I need to license them as 2S systems?

The only one I think is a bit off is the community support level for PBS.

Wanted to get the community's opinion on local (non-redundant) storage for clustered applications. Essentially what I'm thinking of doing is Raid1/ZFS mirrored SSD for Proxmox itself. CEPH for VM general disks But then I'm wondering for applications where the application is clustered and...

I think I'll just setup a homelab instead, it's probably easier to do it on physical tin.

Has anyone had any luck getting proxmox to run in Azure, as some of the machine types support nested VT. I tried to install it on bullseye but it got as far as installing ifupdown and then dropped the VM off the network. I was hoping to setup a Lab cluster on Azure for playing with Pve-Ceph

Setup an API key in proxmox backup server, ideally with just enough permissions needed to do the backup and login with that instead of the root user/pass.

Works fine, I firewalled it to my servers IP's by fiddling with iptables in the PBS installation. Also used the option to encrypt the data before sending it to the PBS server. just remember to backup the decryption keys somewhere else (perhaps your password manager or some such)

Whilst you'll be missing features like shadow copy and I'm not sure if permissions will be preserved it looks like the Proxmox backup client can run in a WSL2 environment and furthermore it appears at least that providing the Linux user can read them it can backup files from the windows side as...

Providing there's enough room on the proxmox root partition I might be able to back it up there temporarily. It always used to backup on when the storage wasn't NFS so I'd say that's a good bet. Also the NFS VM has a local raid vdisk passed through to it, I might also try an NFS export pointing...
