I though the other thread explained that (stripes of) mirrors have better read performance and never worse redundancy. If you want more redundancy and more (read) performance then a 4-way mirror has quadruple the read performance and triple the... -

Like.
Ok, so the issue is, that the keyctl=1 was set on the ct. I was able to make it work by turning it off before moving the CT and then turning it back on again after. Is there a way to increase the API tokens rights? -
RAID5 (with BBU) is almost, but not quite, entirely unlike RAIDz1 (with drives without PLP). RAIDz1/2/3 is not good for VMs but can give you more usable storage (but padding can be terrible for space)...

UdoB replied to the thread Graphical Errors on PVE Webui (9.1.6).I can confirm this. My virtual testcluster was on 9.1.5 and is on 9.1.6 now. I did upgrade without reboots. My logged in session (Linux/Librewolf) shows "0" instead of checkboxes as you describe. In-browser logout/login and/or shift-reload is...

OOnslow replied to the thread [SOLVED] Reject Unknown Clients/Senders.Hi, @olluz It isn't very clear from the excerpts as you obfuscated them, but are you sure these two connections relate to the same triplet "client, sender, recipient"? If the client's IP address was the same, it may mean that the first time the...

JJohannes S reacted to 6equj5's post in the thread Windows Server 2025 VM constantly 50%+ CPU and feels laggy on SSD storage (other VMs fine) with Like.
Absolutely not. Yes. Sometimes this works ok but often not. AFAIK it triggers CPU mitigations in Windows (like for Spectre, Meltdown, or Downfall) which then slow down the VM. So ... choose one of the more general types which resembles your...

JHallo @Bu66as und @Falk R. , vielen Dank euch beiden für den Input. Deine Variante @Bu66as klingt für den Alltag tatsächlich sehr praxistauglich, und wenn es nur der Initial-Aufwand ist der etwas höher ist sehe ich dort kein Problem da ja bei...

JJohannes S reacted to Bu66as's post in the thread NFS-Export scheint beschreibbar, Änderungen erscheinen aber nicht auf Festplatte with Like.
Das Stichwort ist Buffer-Cache-Kohärenz (bzw. englisch "cache coherency"). Kurz zusammengefasst: Jeder Linux-Kernel hält Dateisystem-Metadaten (Inodes, Verzeichniseinträge, Allokationstabellen) und Dateiinhalte im RAM als Page Cache vor. Ein...

JJohannes S reacted to Bu66as's post in the thread NFS-Export scheint beschreibbar, Änderungen erscheinen aber nicht auf Festplatte with Like.
Hallo @joulethief, Das Problem ist, dass du dasselbe XFS-Dateisystem gleichzeitig von zwei unabhängigen Systemen aus mountest – einmal vom Proxmox-Host (und per virtiofs an Jellyfin weitergereicht) und einmal von der NFS-Server-VM über das rohe...

JJohannes S reacted to alexskysilk's post in the thread Best RAID for ZFS in Small Cluster? with Like.
If by redundancy you mean disk fault tolerance, the higher the value after "raidz" the higher the fault tolerance. In practice, raidz2+ (never use single parity raidz unless prepared to lose the pool at any time) performance= striped mirrors...

JJohannes S reacted to UdoB's post in the thread Migrating from mdadm to zfs despite using different disk sizes? with Like.
Syncoid is a tool for "ZFS send/receive". It does work on a PVE installation but it has nothing to do with PVE --> it lacks integration. Regarding LVM: see the last sentence of post #2 ;-)
