Thank you very much! I've said bye to CEPH. It requires to buy new stuff.

Hello, I have a server with 2 disks of 1TB. I installed PVE using the ZFS mirror option, so the two disks are fully dedicated to this whole ZFS mirror. Everything works great. I don't mind changing configurations, but I don't want to add any other physical storage. How could I create a...

Hello. I have three similar computers. Each of them has 2 similar-size disks. I installed PVE on one of the computers and configured its two disks as a ZFS mirror during installation. I recently did the same on a second computer and joined them as a cluster. I was about to do the same for...

Didn't try it, but found this: https://forum.proxmox.com/threads/avoiding-fixed-ip-limitation-from-pve-zsync.111333/

In the end I did run them: proxmox-boot-tool format /dev/sdb2 --force proxmox-boot-tool init /dev/sdb2

Why is not PVE-zsync integrated intro the PVE GUI? Perhaps it is somehow problematic in some way? Isn't PVE-zsync the best option when you have two PVEs in different locations and you want them to be redundant for a quick disaster recovery? On site 1 I have PVE1 and PBS1. On site 2 I have PVE2...

Hello! I have found this very interesting PVE-zsync thing, I would like to use it, but I have read IP addresses must be used to configure it. I have two PVE hosts in two different locations. I would like to sync them so that one is redundant of the other for a quick disaster recovery. They are...

I guess everything is ok now, so thank you very much @Dunuin for your excellent support!

Resilvering is done. Next command to enter gave me this result: root@pbs:~# proxmox-boot-tool format /dev/sdb2 UUID="A0DA-28DA" SIZE="536870912" FSTYPE="vfat" PARTTYPE="c12a7328-f81f-11d2-ba4b-00a0c93ec93b" PKNAME="sdb" MOUNTPOINT="" E: '/dev/sdb2' contains a filesystem ('vfat') - exiting (use...

Rebooted and problem gone! I could successfully execute the next commands, now it's resilvering after the replace. I'll post back when it's done.

Ok. I'm going to try the proposed commands. First, this is where I am: :~# zpool status pool: rpool state: DEGRADED status: One or more devices could not be used because the label is missing or invalid. Sufficient replicas exist for the pool to continue functioning in a...

And I did run proxmox-boot-tool clean after the replace.

I did not. I am checking the instructions now and noticing I did not run proxmox-boot-tool format or init in any way.

I replaced the disk, did the two `sgdisk` commands and had to do: zpool replace -f <pool> <old zfs partition> <new zfs partition> So, as I had replaced the non-working disk, then physically In the system I only had two disks: the old working (ONLINE) device and the new empty device, so I...

But, If I had done so, I guess I would not see the system keeps working perfectly, would I? And I guess I would not see one device shown as online, would I?

Thank you very much. I replaced the disk and then followed the mentioned instructions on the documentation without an issue, but please see in the attached picture what I get now. What shall I do? Thank you!
