"download.proxmox.com" liefert derzeit (bzw. schon immer) ein Zertifikat aus, welches diesen Namen nicht enthält... Nimm "http", siehe https://pve.proxmox.com/wiki/Package_Repositories#sysadmin_no_subscription_repo

That looks weird to me; glad you found a solution.

No, sorry. Some search engines support to filter for (for example) "M.2 with PLP", e.g. this German one: https://geizhals.de/?cat=hdssd&xf=7156_Power-Loss%20Protection~7177_M.2%202230~7177_M.2%202242~7177_M.2%202260~7177_M.2%202280~7177_M.2%2022110&offset=0&promode=true

No, that's the wrong workaround for a well known symptom. The correct (and possibly more expensive) solution is to use "Enterprise Class, with PLP" devices for ZFS. (And probably for all CoW filesystems.) PLP will give you two things: endurance and performance in terms of IOPS for "sync...

While I am basically with you, for me there are some reasons: snapshots are technically cheap, very cheap snapshots are quick, the are created basically instantaneous (on disk level, without RAM) snapshots are created locally - no LAN traffic involved a re-activation ("rollback") is extremely...

Yes! Meanwhile there are several external scripts helping to do so. Search for "cv4pve-autosnap" which is my personal favorite. PS: bugs and feature requests may also be placed at https://bugzilla.proxmox.com/

If that one was usable successfully then 7.4 shall do too, right? Look at https://enterprise.proxmox.com/iso/ - accessible without subscription. But honestly... Debian Trixie = PVE 9 should be installable on that Dell machine!

For a home lab a Raspberry would be fine. For a data center I would choose the first option. You have fiber, so the latency is low. (And irrelevant: https://forum.proxmox.com/threads/qdevice-deployment.173182/post-805735) As I have never run such a construct my reply may not be complete.

Is it a fresh setup? ...or has it run for some time without problems (and without updates)? Which PVE version is installed? (pveversion -v please, embedded in - -tags.) For any memory related problems: check the BIOS for error messages check if the BIOS is uptodate - and update if not ;-)...

Yes and... no, not to the same low level as at the beginning. Unused RAM is wasted RAM - it will be used for caching purposes for example. See also https://www.linuxatemyram.com/ -- and several other threads in this forum...

Great! Please tag this thread "Solved" via the "Edit Thread" button above the first post. You'll find a "Title:" drop-down menu for this.

Try to name that file "pmg-nosub.sources" ;-) For reference: https://wiki.debian.org/SourcesList#APT_sources_format

Ceph on only three nodes may have some disadvantages. My own journey to Ceph ended here: https://forum.proxmox.com/threads/fabu-can-i-use-ceph-in-a-_very_-small-cluster.159671/ How fast is your network? Did you use "good" SSDs for the OSDs?

That's not "reinstalling", that is expanding an existing cluster and then upgrading some old nodes. For me this looks like the way I would go. For the upgrade read https://pve.proxmox.com/wiki/Upgrade_from_8_to_9 in beforehand and consult "pve8to9 --full". There are "hickups" like changes in...
