Just for clarification: my config is (same as of the scond mirrored disk): Disk /dev/sdb: 1.75 TiB, 1920383410176 bytes, 3750748848 sectors Disk model: SAMSUNG MZ7L31T9 Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096...

figured out by my self: After reinstalling it didn't go better - still boot errors indicating problems with pcie and nvme. So, I analyzed my BIOS settings, after changing the pcie settings from auto to pci express 3.0, everything works as expected.

I had a running Proxmox server, booting via zfs raid (systemd). After adding an nvme drive into a pcie slot, the system tries boot from that drive. I see the proxmox bootscreen but when selecting Proxmox to start, then my server jumps to the nvme drive. Can I change this without reinstalling the...

In fact, my next Proxmox- + storage cluster is going to be designed by professionals. I hope they choose the appropriate disks. But I have to care about costs and most important, performance! Nobody can guarantee the system performance when using several SQL servers. And when the system is...

Thank you for your clarification :-)

Concerning SLOG: to my understanding, when using zfs, each data is written twice to the disks: It needs to be written to the ZIL and to the pool - and if the ZIL is within the pool, this reduces my pool performance. If I'm using zfs for Proxmox, I definitely want to use sync writes. So, even if...

Sounds promising, I was proposed to use 4 way mirror whith nvme drives, using a separate vdev for the databases! Does a separate SLOG make sense in connection with 4-way-mirror?

I kow, but for the Proxmox Backup Server I need ZFS as far as I know.

In fact, by now, I was not aware of 'write amplification'. But anyway, I only copied one 10 GB from one disk to an empty one, so I didn't expect such a slow-down. Just one question: do you think, in real world (Proxmox cluster + storage cluster with zfs, of course with enterprise SSD) zfs is...

In fact, I was hoping that the MX500 is the bottleneck. This setup was just for testing. In my productive system I would use server SSD. I just thought, that the difference was not that high (because in a desktop client the MX500 performs well) Thanks for your help :)

So, I was busy last days, I just checked again: I already installed 'virt_io_win_driver_installer' ans 'qemu guest client'. Are there other drivers I have to install?

VirtIO SCSI, I tried different cache settings but no other tweakings!

I know there are tons of questions, but I couldn’t find a satisfying answer. For performance testing I’ using an old server: HP Dl380 Gen 10 Server, just one Xeon E5-2609 installed, 16GB RAM. Proxmox is installed on a hardware raid (scsi hdd). Two consumer SSD (Crucial MX500), each one with one...

I'm sorry for that, it's just a hobby. And I don't get your point from your last post. I think I'm using OpenSSL 1.1, so I should not have any problems but I have. Fortunately, my backups are running fine with the self signed certificate as long as I don't understand my issue.

I thought so already. But in fact I'm happy that I was able to got the LetsEncrypt certs running at my home servers. But I don't know how to change the chain (I never thought I need to concern about that). For my nextcloud server I also have a (different) LetsEncrypt cert and after 29.September...

linux-vdso.so.1 (0x00007fff6b5f6000) libacl.so.1 => /lib/x86_64-linux-gnu/libacl.so.1 (0x00007f941f22f000) libzstd.so.1 => /lib/x86_64-linux-gnu/libzstd.so.1 (0x00007f941f190000) libfuse3.so.3 => /lib/x86_64-linux-gnu/libfuse3.so.3 (0x00007f941f152000)...

So finally I got my backup working again - but without the LetsEncrypt Certificate. I created a new Self Signed Certificate on the PBS and used the fingerprint for the PVE. I also tested a renewed LetsEncrypt certificate from today - same issue. So by now I'll stick to the self signed certs on...

BTW, thanks for your help so far,:) it seams the DST Root CA X3 is the problem. I probably have to get a new cert for my domain! I'm just wondering why the web GUI is working fine with the same cert! CONNECTED(00000003) --- Certificate chain 0 s:CN = *.mydomain.de i:C = US, O = Let's...

infact my backups stopped working on 29.September. but that would mean, pve is not trusting ISRG Root X1, makes no sense. how can I figure out, if this is my problem? In a first step I coud try to remove the letsEncrypt Certificate and use the fingerprint with self signd certs.

I get a certificate expired error. But when I connect vie browser to my PBS the certificate is valid 29.November 2021. So what is the problem? Are there different certificats for the web gui and the pbs server? The Certificate is a wildcard certificate by letsencrypt (I manually uploaded the...
