UThere are some myths around SLOG, L2ARC and special device(s) in ZFS which always re-appear. 1) SLOG A SLOG is a separate storage for the ZFS Intent Log (ZIL). Synchronous writes are protocolized and written back in the ZFS pool later. For...

Gefühlsmäßig hätte ich mich für ein RAID-Z2 entschieden. @Falk R. : Du hast mich zwar schon zu einem Hardware PBS überzeugt - aber SSD only ist aktuell einfach zu teuer. @UdoB...

Like.
Udo und Falk haben zu special device, log device und SSDs versus HDDs und RAIDZ schon genug geschrieben. Ergänzend folgender Blogpost von Jim Salter: https://jrs-s.net/2015/02/06/zfs-you-should-use-mirror-vdevs-not-raidz/ Seine Argumentation... -
Wenn du im PBS wie produktiv empfohlen nur SSDs verwendest, dann kannst du auch mit RaidZ# arbeiten. Ich habe PBS mit All NVMe und RaidZ2 sowie einem kleinen NVMe Mirror als Special Device bei Kunden im Einsatz. Das läuft gut, aber mit HDDs...

Same with me in a simpler architecture: upload large immich data (some videos) then crash the truenas VM. within same log here. This issue can be reproduced easily. ``` Proxmox node syslog...

Francois Baillargeon replied to the thread PVE VM replication standalone host to 3 node PVE cluster with CEPH shared storage.IANAL but I think running the disk on the Ceph cluster is probably your easiest bet, that said, won't that run contraty to your wish of being separated? -
news replied to the thread Storage-Anzeige in GUI auf local-zfs beschränken / Backup-Storages ausblenden.Was mich mehr verwundet ist, dass, der OP ein ZFS Setup nutzt und nur einen Datenträger einsetzt. Dann noch das Setup auf dem Promox BS mit jeweils nur einem Datenträger pro ZFS Pool. Das macht keinen Sinn! Wo bleibt die Sicherheit? Warum lese... -

Francois Baillargeon replied to the thread VMware OVA Appliances on Proxmox !.Normally you can import them, that said, they might have been built with VMXNET3 and pvscsi so you will have to tackle that.

RaidZx reduziert die IOPS auf die einer einzelnen Spindel. Es liefert also - egal wie viele Festplatten in dem vdev enthalten sind und egal ob Z1/Z2/Z3 - immer die geringste Anzahl Operationen pro Sekunde. "Auf keinen Fall" weil dies eben das...

Aalpha754293 replied to the thread Containers on GlusterFS?.Again, I understand that native support for GlusterFS has been removed (qemu removed it, so it really has very little to do with Proxmox itself). But that still doesn't answer the question as to why the native GlusterFS client didn't support LXC...

JJohannes S replied to the thread Containers on GlusterFS?.This will change as soon as the qemu version integraded in ProxmoxVE doesn't have gluster-support anymore. Since qemu deprecated it and announced that they will remove this feature at some point Proxmox developers removed it too...
