I have a PBS running on NVME but the datastores are on ZFS arrays of HDD's. The problem is scheduled tasks can all run at once so you get in a situation where IO wait is like 30% because the disks are thrashing. I can't predict how long each task will take so I can't manage this with...

You can recover the backups. You create the datastores in PBS on ZFS on your hard drives, ideally in some sort of redundant layout. You can re-install proxmox if you like on a new NVME you will still be able to import the ZFS pools. Just keep a copy of /etc/pve/ config files to restore...

Gabriel - thanks, I've corrected NAS to DAS, I do understand the difference one connects by usb and the other by ethernet. I actually wanted USB so that I could manage the ZFS on proxmox. I accept its just something on the new box it doesn't like and the mac is ok, the mac isn't the...

Hi All, Please to ignore the vast scope of this post. Its my experience and I'm not sure what the problem or what's possible at this point. TLDR; This is about problems running Proxmox for homelab / media centre on cheap unsupported hardware that's not well documented. I had a Mac Mini 2012...

Actually - I think you must be right - its the letsencrypt cert changing - and thats the fingerprint its checking against, not the fingerprint reported by the backup server. My confusion here was that on pve hosts and have pvb installed on the same machine the fingerprint always matched, but...

I don't know. Do I mis-understand something here? I thought when adding storage I have to enter the fingerprint of the destination server?

I can send you a video if you like?

No proxy or dns issues that I know of. Its very odd, the backup works if I use the wrong key and arrives on the backup server.

I have 1 proxmox backup server fingerprint ED:ED:xxx etc. 5 of my servers have no problem with this but one of them is insisting that a different key is needed. vzdump backup status (elvis.xxxx.xxx) : backup failed: could not activate storage 'datastore-elvis': datastore-elvis: error...

Reboot the server in IPMI, press del / F12 whatever it says to go into setup you can change the boot order there. Remember - to reinstall via the OVH web page you need to revert this to rEFI before it will work.

Thanks. I switched to backup using the 'shutdown' mode, instead of snapshot and this does give a consistent backup and its only down for 44s at 2 in the morning. But if you do this you lose the benefit of the dirty bitmap to just save the changes. I'll try the hook approach. Cheers! INFO...

I've got three mysql vms, running on latest proxmox. Server version: 10.6.5-MariaDB-1:10.6.5+maria~focal-log mariadb.org binary distribution. db1 - master, runs fine. db2 - slave, runs fine, no apparent corruption, passes mysqlcheck etc I am running backup to a proxmox backup server, but when...

I'm having the same issue, concurrent tasks causes IO delay to hit 70% then its starts crawling

ok - will do - thanks

Do you think it would be sensible to show the duration ias hh:mm:ss, or also in that format? 11398 seconds is a bit meaningless unless you can divide my 60 in your head.

I am referring to the block size box when you add the zfs dataset in the gui. I set the recordsize of the dataset on the cli, then add the dataset onto storage on the gui. I assumed this was the vol block size used in vms that add hdd's from that storage
