they are no problem with PG autoscale, it's really depend of what you want to do with ceph. you could have multiple pools (in this case, need to define target ratio for each pool depending of what you want to do with your pool). you can have rbd, radosgw/s3, cephfs. same for erasure coding K+M...

here a small blog article about new fast erasure coding implementation && partial read , and some benchmarks inside too https://ceph.io/en/news/blog/2025/tentacle-fastec-performance-updates/

The main problem with PG autoscale, by default, if your pool is empty, it'll not set a lot of PG, and this can slowdown write a lot (because of pg lock). You should have between 100~200 PG by OSD (you can see them osd by osd on the osd tree). The most simply way , when you have only 1 pool, is...

@alpha754293 - how many PG do you have on your ceph cluster ? (new pool on empty storage are setting low number of PG by default with target ratio is not configured on the pool, and this can give very low write speed). - do you have enable writeback on your vm ? (for ceph, it's really...

what is the benefit ? you'll have same performance but no snapshot and no replication support.

200MB/S with which block size ? iodepth ?

Hi, I wrote a script to automatic install from debian iso + proxmox package (using debian preseed + proxmox kernel && shim && grub) https://forum.proxmox.com/threads/tutorial-proxmox-ve-unattended-installation-over-debian-with-secureboot-crypto-lvm-for-cis-compliance.183880/

Hi, I have wrote a script to generate an iso install with debian + proxmox package merged + debian preseed file for automatic installation, with crypto lvm + specific partitions for CIS compliance. It's using secureboot with proxmox shim && grub packages. You can simply tune the preseed file...

ARP && ND is filtered by default, until you enable the option "Disable ARP ND Suppression". at layer2, the vnet address is not used at all. The bridge/vnet are forwarding through the vxlan tunnels between nodes in same vxan directly. (with the mac address routes in bgp evpn tables) At...

They are not going to works fine with zfs, sorry. you really need enteprise drive for zfs. (at minimum for the slog devices). just look at this thread with same disk (it was with ceph, but it's the some zfs, you need drive with fast sync write)...

note that you can use HA with local zfs replicated between node. (but you can loss the last non synced datas snapshot). you could have better resilience than a single NAS (or do you have 2 truenas nodes with a shared array ?) About your truenas, what are the ssd model ? enterprise ssd wih...

note that you can configure the token permissions to have only audit access for monitoring, without backup/restore permissions. (I'm not sure about default permissions when pdm is generating the pbs token)

I have r610,r630,r640 in production. I never had problem with drivers.

7.0 is optin and you can still boot on previous kernel in grub. And only availaible in non subscription repo. So, instead complaining, please report your nic model. Is it a pbs vm on proxmox ve ? Or on vmware ?

move your cluster_network ip on the 100Gb too. (cluster_network is used for osd replication when defined, so it's limiting your write speed) auto nic4_100G00 iface nic4_100G00 inet static address 10.180.194.211/24 address 10.180.195.211/24 #CEPH
