Ok, agreed. This makes sense. In which case having a SW raid makes more sense. Although some of those things could not be mitigated by ZFS either. e.g. let's say there is an issue with the controller that messes with all connected disks, what can ZFS do then? But I see your point. Thanks.

Hmm, but that's why there is ECC RAM. e.g. I run all my ZFS on ECC RAM systems. Nope, which is why I said that I would not recommend it. Yes, this is true. But why do I need a PRO CPU that is so much more expensive than a regular CPU. Truth be told, according to HW designers these are...

Please explain why. The ZFS does not know it is on a HW raid. For the ZFS it is the same as a single disk. ZFS allocates a page on the storage. This page is the same for ZFS wether or not a HW RAID is used. ZFS sees the page, not the storage. If you built a RAID with ZFS on a HW raid, you would...

This is something that makes no sense. If it is a true HW RAID, the underlying OS and thus filesystem does not know that the block device is actually a RAID array. So why would there be an issue with ZFS? Unless you talk about possible perf issues which should also not occur, since the HW RAID...

I was trying to setup a notification matcher, but got stopped in my tracks when setting up a match rule: Node type: Match field Field: type So... where do I find the value for type? In the documentation I was able to find 4 different event names. Are these the types? If not, how do I find...

Thanks again for your reply. Ok, so the latter of the 2 options in my question. ;-) Thanks, I also wrote a similar script a long time ago.

Thanks, I know how to convert images. I was asking whether there was an export command in Proxmox (something in pvesh or another tool), or whether I had to convert the image myself. After that it would be good to know whether I can do that while the VM is running or from a snapshot, or do I...

Thanks a bunch for the reply. Yes, this seems like a great way to exchange images between Proxmox users/servers. I am not sure why I didn't think of this myself. Ok, now let's turn it up a notch: there might be a necessity to make an image available to people who are not using Proxmox. What is...

I have a fairly nice VM that I would like to share with someone, who is also running Proxmox. How can I export the VM (plus disk), so that they can import it on their Proxmox server? (same as cloud images in qcow2 or raw format, plus the VM meta data .conf file) Is there a way, or do I just...

Thanks, Richard. I am aware of that workaround (and as I mentioned I understand and know why the iSCSI disk cannot be included in the snapshot). Here is a use-case of a snapshot. I create a snapshot, before I do any experiments on that VM or a major update - or if I know I have to rollback to a...

Is there a way to tell Proxmox to ignore an attached iSCSI disk during a snapshot? I added a second disk, like so: scsi1: name:0.0.0.scsi-3600120516fb1dc8dbcfbd4334add3ed4,backup=0,cache=writeback,size=4T Since then I can't take any snapshots anymore. I do understand why that is, but here is an...

I know that I can set the txqueuelen for an interface via the ip command. But I do have a few questions with regards to bonding and/or the bridge adapter, and the interfaces that are created for every VM. Here is my /etc/network/interfaces (basically a VLAN aware bridge on a bonded interface)...

Ah, nice. Thank you. I didn't know that I could stop a task in the task log. Not very intuitive. Right click didn't do anything either. But double-click worked. One can learn something new every day. I don't really need anything else. This works and I don't have to login to the host and kill...

I am running Virtual Environment 7.3-4. When I start a Linux VM and press ESC in the Grub menu, I can't shutdown the VM. I only see a spinner in the columns End Time and Status. It never times out. I waited for about 7 minutes. I can only kill the VM by going to the host and kill the kvm...

Thank you. This solved it.

The summary page on the datacenter folder show the wrongamount of storage: In reality these are the correct numbers (as shown in the only node I have under Disks/ZFS): First I thought that it might show the raw storage, but that's not it either. All of these pools are mirrored, so the raw...

Thanks a bunch for your reply. Your test confirmed it's either a 32bit (signed or unsigned) integer. Signed or unsigned doesn't matter much in this case, since the number of digits won't change. But I will have to adjust my format. And yes, I could have tried. Stupid me, sometimes the obvious...

I checked the documentation and searched the Net, but couldn't find an answer. What is the max value of a VM ID? In the man pages I could see that it is an integer: <vmid> <integer> (1 - N) Is it a 32-bit integer? Unsigned?. 64bit? Even if it's just a 32bit int, it would mean that N could...

Thank you!

I've read a few threads on this forum about removing old kernels. At one point the autoremove feature was mentioned, but in other threads it was suggested it was not safe to use. Another thread mention apt purge and update-grub. I couldn't find a definitive answer. # apt upgrade Reading package...
