Thx! proxmox-backup-manager versions proxmox-backup-server 4.1.0-1 running version: 4.1.0

I don't have enough knowledge and examples from the official documentation. I don't understand how to implement sufficient redundancy for the Erasure Codes pool to allow one data center out of three to crash. At the test site, I achieved an even distribution of servers in each datacenter. Five...

I need to implement fault tolerance at the datacenter level in the Proxmox VE hyperconverged cluster (pve-manager/8.1.4/ec5affc9e41f1d79 (running kernel: 6.5.13-1-pve)) and Ceph Reef 18.2.1. To test future changes, I created a virtual test bench in VirtualBox that closely mimics my cluster in...

Please help me with some advice. In my test scheme with three data centers, I need to create an Erasure Code pool for cold data. I used the documentation https://pve.proxmox.com/pve-docs/chapter-pveceph.html#pve_ceph_ec_pools My chosen k=6,m=3 (I also tried from the documentation k=4,m=2) in...

Thank you very much! Everything worked out: I added a third datacenter, moved some of the servers to it. The Ceph cluster has balanced the data.

I updated my cluster and the problem was fixed. Thanks for the great job. pve-manager/8.1.4/ec5affc9e41f1d79 (running kernel: 6.5.11-7-pve)

And where to get the utility pve7to8? # pveversion pve-manager/7.4-3/9002ab8a (running kernel: 5.15.107-1-pve) # pve7to8 -bash: pve7to8: command not found # apt show pve7to8 N: Unable to locate package pve7to8 N: Unable to locate package pve7to8 E: No packages found # dpkg -S pve7to8...

I'm very sorry, but I just waited a little longer and the reading speed increased. Perhaps earlier changes to the ZFS ARC settings helped.

I have read all the forum posts related to slow GC. I have to bring this topic up again and ask for help. I use PBS 2.3-2. The work of the disk subsystem does not cause any complaints. Carried out the tests: 1) with copying a single huge file. 2) unpacking their documents from the archive to...

I decided to use the ZFS functionality of changing the mount point zfs set mountpoint=/mnt/zabbix SafePlace/zabbix # zfs get mountpoint SafePlace/zabbix NAME PROPERTY VALUE SOURCE SafePlace/zabbix mountpoint /mnt/zabbix local

The hardware server for Proxmox Backup Server is very powerful. Due to budget constraints, I was forced to use part of the server's capacity for another task - MySQL for Zabbix. I had to allocate space for huge Zabbix MySQL tables in the same SafePlace pool that Proxmox Backup Server uses to...
