HA! got it working again. As it seems the primary GPT table was corrupt. I've just rewrote it, and now I'm able to import the pool. How it got corrupted only the gods know. Thanks for your help. It made me revise everything again.

Welcome to fdisk (util-linux 2.33).

I don't remember anymore wich Proxmox version the installer was. But the whole partition layout and everything was created by it. I can't remove sda and boot from the other part from the mirror, since the other disk is completely death.
I've tried to detach sda from the pool. But as it seems I...
We normally shutdown a server. Just before doing that I've checked "zpool status" and everything was alright. Then when starting up the server again, on of the disk drives failed directly on powering the server on. We were using a zfs mirroring configuration. So theoretically the server should...
I've got exactly the same Problem.
That was one of the reasons why I've updated to proxmox 6.1. But the proplem still appears.
The interesting thing is it only happens on two out of 3 servers. They've got the same hardware and software. The amount of virtual machines running are different. On...
I guess it depends what you use it for. If your server is backed up by a ups, then the only way you could loose data would be if the host OS crashes or your hardware utterly fails. The changes are relatively low. Anyway you would loose around 5seconds of data (The data will be written back every...
I've read at several places in this forum that people consider sync=disabled to be save.
I've found out that the block size of 16kb on btrfs is only for the metadata. The block size for the real data seems to be 4kb. So increasing the zvol blocksize shouldn't really help (i guess? ;-)).
I also want to use UrBackup (But I'm more interested in the endless incremental style backups, which is possible to do on zfs and btrfs). I first tried to get it working in a LXC container, but it wasn't that easy to manage to allow it to directly make snapshots etc. out of the container.
So I...
Thanks a lot for all your replies.
I finally made it a bit differently. I'm using single failover IPs, not whole subnets.
But basically on each node runs a iontifywait process which checks /etc/pve/qemu-hosts and changes the routing of the failover ip, and also adds the local route needed for...
Personalyl I just think it's bad practice activating vulnerable services in a default installation. There where enough news in the last few years, about services which in it's default configuration are unsecured and were actively abused.
This one even doesn't really affect the functionality of...
it works. Manually I can switch failover IPs and VMs easily in 2 minutes... But obviously the plan is to automatize that.
Once we finished the whole setup I can publish our internal wiki for the whole setup. So other people don't need to start at zero...
I am. It looks promising :-).
Any chance...
Hmmm I've just realized that proxmox doesn't use rgmanager anymore, so ocf scripts won't be a solution in any way...
There also seem to be no hooks or anything to call scripts on migration.
Did anybody solve that nicely, with some kind of cronjob or similar?
Hi all
I was just wondering if anybody uses Hetzner with a failover ip.
We would like to use it, and automatically switch the ip over from one machine to an other when a certain machine migrates.
The only solution I've found so far is...
Hi
I've just made a new proxmox installation a few days ago on a server in the internet.
Today I've got a message from the Server provider that the BSI (German Federal Office for information security) contacted them, that the server can be abused for DDoS Reflection attacks.
I've just...
I don't know where the randomness comes from for the ssh key generation. But I thought that at least /dev/random is blocking, i.e. waits until there is enough entropy.
I tried to do the installation like 4-5 times changing some parameters, but always the same result.
At the end I did the...
so here we go. Took me a while to get it out of there.
The whole thing was installed in a vm with qemu using zfs as filesystem:
qemu-system-x86_64 -m 4096 -hda /dev/sda -hdb /dev/sdb -cdrom proxmox.iso -boot d -vnc :0 -k de
(it''s on a remote server where I don't have physical access).
