    UdoB reacted to Impact's post in the thread Proxmox VE 8.4.1 - Restore Failed to Load Boot0003 nach Restore/Backup with Like Like.
    Ich kann dir zwar leider nicht erklären wieso ein MDADM RAID solche Probleme verursachen sollte, aber generell wird ZFS dafür empfohlen. Da die PM9A3 SSDs Datencenter geeignete Hardware sind, sollte das auch wunderbar funktionieren. Kommt etwas...

    Wenn du die Kapazität brauchst und die Performance eines Software RAID5 reicht, kannst du eigentlich nur RaidZ1 nehmen, wenn es stressfrei laufen soll. Ein Software Raid10, was deutlich performanter ist, kann auch mdraid, btrfs oder zfs sein. Mit...

    UdoB reacted to DerekG's post in the thread Proxmox with private IP's and router. with Like Like.
    Not so confusing, your private subnet 192.18.1.0/24 addresses the IP range from 192.168.1.1 to 192.168.1.254, so if you fix the IP of the Proxmox node to 192.168.3.1 it is sitting outside of your IP range and thus unable to communicate with the...

    UdoB replied to the thread Ugreen DXP4800 Plus Konfiguration PVE.
    Ich auch. Sofern beide Sorten technisch gleichwertig sind. Wenn jedoch nur die SSDs "Enterprise w/ PLP" ("S3610 oder S3710") sind, die ungenannten NVMe - wie so oft im Homelab - aber nicht, dann würde ich es umgekehrt machen. Anders formuliert...

    UdoB reacted to dokkenrolf's post in the thread NAS UGreen DXP4800 Plus with Like Like.
    Proxmox VE ist ein Hypervisor und kein NAS-System, also wird darauf kein NFS oder Samba als Server installiert (als Client natürlich schon). D. h. du könntest jedoch auf Proxmox eine VM mit NFS-/SMB/CIFS laufen lassen (z. B. Ubuntu-Server...

    UdoB reacted to Johannes S's post in the thread [SOLVED] Update Strategie with Like Like.
    Auf jeden pve läuft auch ein postfix, aber das ist gar nicht der Punkt ;) Mailrise arbeitet als smtp-Gateway, dass Nachrichten per smtp entgegen nimmt und dann als notifications weiterleitet. Dass kann man sich also auch in einer VM oder einen...

    UdoB reacted to cwt's post in the thread windows vm crashing / hanging with Like Like.
    Hardware RAID5 or ZFS RAIDZ is a poor choice for VM storage because it destroys the I/O characteristics virtual machines rely on. VMs generate huge amounts of small, random, sync-heavy writes, and RAID controllers, parity overhead, caching layers...

    UdoB reacted to bbgeek17's post in the thread Issue with attached ISO, cannot migrate VM to second host with Like Like.
    This situation seems to me as a candidate for improvement. An ISO reference in snapshot should not prevent HA/manual migration, or require snapshot deletion. When/if the system rolls back to that snapshot - there is no guarantee that ISO is...

    Verify pvestatd status and pvecm status. Restart it if necessary: systemctl restart pvestatd.service.

    UdoB reacted to Johannes S's post in the thread The New Guy to Homelabs based on linux with Like Like.
    How are you doing your backups? The integrated backup features of ProxmoxVE won't save anything on the HBA-attached storage so you need another solution for that. if you don't want to learn Linuxism you shouldn't use ProxmoxVE and you should...

    UdoB reacted to Johannes S's post in the thread [SOLVED] Update Strategie with Like Like.
    Automatische Updates kann man bei Debian und seinen Varianten (wie ubuntu) wie von Udo erläutert mit unattended-upgrades einrichten. Standardmäßig alamiert das über mail, aber mittels mailrise kann man diese Mails auch an andere...

    UdoB replied to the thread zfs fehler.
    Und was war damals die Lösung? Das Installations-Iso bietet einen "Emergency"-Mode, da drin kann man (Software-) Fehlersuche betreiben und versuchen den Pool zu importieren usw. Dass zwei Platten gleichzeitig ausfallen ist eher ungewöhnlich...

    UdoB replied to the thread upgrade from 8.4.1 to 9.1.
    Adding OSDs should work on-the-fly. Actually Ceph's basic functionality makes sure to have no problem if one OSD dies - and it has no problem when one or more are added. Be aware that re-balancing will introduce some - or a lot - traffic...

    UdoB replied to the thread upgrade from 8.4.1 to 9.1.
    Well..., I'm sorry. The more unusual a specific setup is the lower the chance for a helpful answer. In you case I can not help because I do not use OVS, do not use bonds and do not use Full Mesh. Actually I am fairly sure the number of active...

    UdoB replied to the thread Issue with attached ISO, cannot migrate VM to second host.
    Yes. You see only the current state. The .iso is referenced in those snapshots. The clean way is to remove the snapshots. If you're brave enough you can make a backup(!) of ".../qemu-server/104.conf" and edit it "under the hood" to remove those...

    UdoB reacted to LnxBil's post in the thread Trim best practices - Ceph/NVME-OSDs with Like Like.
    Enterprise drives should not need manual trim so I never looked into it. However, I always trim the guests, but mainly due to thin provisioning reasons (discard).

    Sorry, I have no access to my subscribed hosts at 9 p.m. ;-) My homelab/non-sub has ~# apt policy pve-qemu-kvm pve-qemu-kvm: Installed: 10.1.2-4 Candidate: 10.1.2-4

    UdoB reacted to Impact's post in the thread local-lvm troubles with Like Like.
    I recommend ZFS if possible. With this you can use replication as well making migration very fast and HA possible.
