Right. Well, I have tried twice and what little space pruning released was not enough to let GC run. And didn't want to prune everything in order let GC then remove it all because then - what would have been the point in trying to save the datastore. But I get what you're saying.

Backup isn't a problem - thanks to PVE and PBS ;) But if there isn't a tried way of switching to BIOS, I won't bother because fixing hundreds of issues will take longer than simply reinstalling the OS and the software on it.

Theoretically, I agree. But in reality there was nothing that should cause a big backup delta. No new VMs, no new drives in VMs, no large data changes on drives in VMs... That's what didn't work. It is my understanding that pruning doesn't remove data but only marks it as removable and GC is...

Hmm, it wasn't the log but rather the status line. Looking at it again, maybe this is the sum total of all collected garbage ever? In any case, GC ran and did something. The datastore is on ZFS. Why GC can't run anymore, I don't know. It complained about the disk being full or no space being...

Hi, So I installed Windows into a VM with UEFI - because I thought this would be overall "better". Now I found out that with UEFI, I can't switch the VM's screen resolution inside the VM but have to do that in the UEFI at boot time (for the next boot) - at least for VNC purposes. That is...

Hi, I have a PBS running for a while (two years?) now with apporx. 25TB worth of storage. Regularly, I check how much space is left / when the datastore is going to be full. A couple of days ago, it said that it was running full in a bit of 50 days. So I decided to make room and so I combed...

Thanks for the tip! ATM, I'm not even sure I need IPoIB mode. All I want is setup to be easy, as I am totally new to IB. It would certainly be easy for me, if everything behaved like my current ethernet network. Because I have no idea how to think about the whole network, if the nodes don't...

Not sure I understand this fully. Does that mean you can use the IB cards and switch like you would otherwise use ethernet cards? But you can't use the switch with ethernet cards and cables directly, right? There seem to be splitter cables that connect to the SX3036 (or other IB switches) and...

So, the SX6036 I received is on 3.6.8008. This means that my switch can do QSFP56 already (I don't have the cables for that atm -- they cost an arm and a leg, so this is only theoretical), right? (The most current version I could find, seems to 3.6.8012 (which is from end of 2019). I will try...

The next issue I'm facing is that, with 10gbe, I am running 3 networks: Corosync, Ceph and backup. But with the Infiniband cards, I only have two ports per node. The first network I am going to replace is backup. But I then need to decide what to do with the other two networks. - Only switch...

One more question about the infiniband cables: There seem to be (normal) copper cables and there also seem to be fiber optical cables. Both seem to have the same plugs at the end. Can I use either copper or fiber or can I only use copper? And if I can use either, can I mix them in one switch...

Okay, so it's working again. I don't know what exactly did the trick and it might not be a solution to apply in similar situations, I'm afraid... So what did I do? Well, I have been waiting to switch from 10gbe ethernet to Infiniband for a while (I opened another thread in that respect). My...

Yes, I have not rebooted.

Fortunately, I migrated the important VMs away from the upgraded node before upgrading. So they reside now on the quorate two node part of my cluster. I think I will wait and hope that tomorrow the Proxmox guys know what to do. But thank you for your thoughts and time!!!

No dice

I checked the output of systemctl corosync.status and, among other stuff it says on the upgraded node: A new membership (4.6c7) was formed. Members joined: 4 whereas on the other nodes it says: A new membership (1.6c1) was formed. Members left: 4 Since you suggested that there might be an...

I am just now looking into pve-cluster.service with corosync.service being the next in line.

Ext4 on all of them. (I think I did install PVE on ZFS a few years ago (prior to my current cluster) and this gave me some other (booting?) issues and so I refrain from using ZFS on the boot drive.) So, unfortunately, upgrading is a one way ticket for me...

It would seem so. Unfortunately, neither is an appealing choice...
