So I have PBS running to backup my home lab cluster. And it is working fine and I backup everything there and from there on tape as well. As data protection is becoming more and more important, I am wondering whether there is a way to selectively remove individual files or folders from not just...

This may have been the decisive advice. I wanted to keep my to-be-replaced node untouched until the replacement node was completely up to speed. And I had thought that monitors, OSDs, etc. on an offline node would have no negative impact. But with your advice, I booted up the to-be-replaced...

Oh FFS! How can there even be something like an IB card that can't do IB? Anways, so does the "EN" signify cards that can't do IB? In other words, when I buy new cards, will I be safe, if I avoid "EN" cards? Is there anything else that I would want to avoid? Is there any value in buying "VPI"...

Man, this is proving so much more complicated than I anticipated (and I did anticipate issues...)! So mstconfig tells me Device #1: ---------- Device type: ConnectX3Pro Device: 65:00.0 Configurations: Next Boot SRIOV_EN...

There is one monitor on each of the three (online) nodes (and one on the offline node as well). Understood. But I would need to so many OSDs per node that my energy bill would become fully unsustainable :( However, this should not affect rebalancing, right?

Hi, I am getting SMART error notifications from PVE every day about the same one error (there is 1 unreadable sector on one of the SSDs). While I appreciate the notification in principle, I don't need to be reminded of the error every day. And if nothing changes, I think I can live with that...

No, I just shut the node down. Ceph complains about the missing node and the missing OSDs. But it did copy over a good part to the new node and new OSDs before it stopped. The same goes for the monitor service. But there are enough monitors in the cluster. Between 44% and 55% I don't have...

Hi, I have a small three node cluster. There are two pools with three OSDs each. Each node hosts one OSD from each pool (one HDD, one SSD). Replication rule is 3/2. When one of the OSDs in one of the nodes started acting up, I decided to not just replace the OSD but to also replace the entire...

So, I have made the step and connected everything but hit a wall: While I can see the cards in the PVE GUI and have assigned them IP addresses and they start up, they can't connect to one another via the switch. At first I thought that I needed to change some settings on the switch (and that...

Ah, thanks. I think I knew that a long time ago (because I had actually switched this to one of the 10gbe networks) but I had since forgotten about it...

Same issue here with CX3-Pro card and PVE8.2 Has anyone got those to work?

I have installed the new IB cards in all hosts but have not yet made the switch because of one (hopefully final) question that came to my mind: When I migrate VMs from one host to another, which of the networks is used for that? If it is the corosync network, then switching it back to 1gbe will...

Not sure whether this is a config or a networking issue... I tried to connect to the shell via the GUI. It said connecting and then "Connection failed (Code: 1005)" Background: This works perfectly fine when I access the GUI directly locally. But when I access the GUI remotely via...

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...
