Sstr1de replied to the thread Looking for best setup for rack server.Thanks for the reply! I also contemplated putting in a m.2 drive via PCIE 3.0 card to strictly hold proxmox so I don't touch the 8 drives at all. Would that still be a good idea? Something along these lines PA09-X1 M.2 NVMe to PCIe 4.0 X1 Adapter

LLombra replied to the thread Mounting directory writable in container?.That sounds like it would work well. Thanks! So it just maps the guest UID to the same host UID? Are there any non obvious security implications that I should keep in mind?

Aalma21 replied to the thread Looking for best setup for rack server.Hi, ZFS memory consumption is configurable and Proxmox VE takes 10% of total memory for ARC cache per default .... so this should not be a problem .... if no HW Raid Controller exists then ZFS is the only supported SW RAID solution ... 2...

Nns33 posted the thread [SOLVED] Pinning vCPU causes 100% cpu pressure stall, using isolcpus in Proxmox VE: Installation and configuration.I have VM which runs an app requiring low latency as close to bare metal as possible. Note it is not a game but something doing compute. Maybe putting such in a virtual environment isn't the best scenario but I'm going to try Quick system arch...

TTErxleben replied to the thread PBS meets Hetzner Storagebox.Der timestamp deckt den nano-Sekundenbereich ab. Sollte ja auch reichen. Für rsync ist die Quelldatei immer die "heile" Datei, wenn sie neuer ist oder eine geänderte Größe hat. Sobald eine der beiden Kriterien zutrifft, sendet rsync Deltas. Ich...

I experienced the same issue with a Linux guest and a VirtIO-FS share containing about 1.3 million files. In my case, the host filesystem is ext4 on LVM. virtiofsd continuously increased its number of open file descriptors and hit its limit...

Aalma21 replied to the thread Proxmox in enterprice environments with shared fc storage.... although OCFS2 has some nice features - with reflink in combination with raw (sparse) files you get FS native/clustered thin provisioning and snapshots ... and maybe raw is also not so vulnerable as qcow2-on-cluster-FS .
