With all respect that was not the question. "works" is wage statement. I'm pretty sure it works on usb flashdrives. I'm asking if someone has one some setup on el' cheapo drives.. 2 drives per node etc. and what the performance on direct IO (no random IO) would sound like.

So i'm slowly getting to the point where my small cluster is getting important enough to have redundancy. I'm already running local storage on zfs and samsung entry level nvme's and performance is great.But looking at moving my mechanical backup to something more "solid". So as i know that ceph...

Cool.. i was able to upgrade half of cluster to 5.19 kernel and saw that migration issues between amd and intel dissapeared. But now few days later it seems 5.19 kernel has been scraped as it was replaced with 6.1 kernel. Oh well. Nice timing on my side. Restart all the testing.

I just found that there was still my old node data available on the /etc/pve/nodes path. So just to test it out I just created dummy 1.conf file in the qemu-server subfolder and it immidiately added this node to he list of nodes in web ui. Of course it's with quiestion mark. After removing the...

Just stumbled on that too. yes - nodes were different versions and was fixed with update and reboot of node. @Talha please mark it as solved also.

I can't much as I don't understand what information you are seeking on this matter https://www.tecmint.com/clear-ram-memory-cache-buffer-and-swap-space-on-linux/

You probably won't kill the clustet, but you can backup it and remove it and test if something goes wrong. You can always put it back. Just don't do it on working hours. Anyways thanks for the tip on removing the /etc/pve/nodes/<node> folder. I got to same point where it deleted the node but...

Just updated to latest Proxmox ( 7.2-11) and started having same issue. The command described above will fix the issue for this boot.

I believe the end speed depends on speed of the cpu single core and contents of memory. I could achieve around 25-30Gbit/s speeds over 100Gbe SFP links, no RDMA (directly connected on 3 node cluster) on AMD epyc 7401P (ceph as storage, so memory copy only). using jumbo frames might drop some...

Had the same problem on 5x8TB disk raidz2. 25% of space was lost. It would have been the same as having RAID10 instead (cost of one added drive not considered). It was default 8k volblocksize and 128k recordsize. If I used 64k volblocksize I got away with 10% of wasted space and bumping...

I think you are totally overthinking or not thinking at all. I did not say to rename scsi0. I said rename scsi0 storage name. It has your vm id. So like in my case I have id 1001 machine and like it to be 5001. So: 1) rename 1001.conf => 5001.conf 2) edit the config: scsi0...

I am not interested in disabling auto assembly. I was interested disabling auto assembly for zd*. Since I can't think of way make negative glob ( can it be even done?) then I just ended matching for scsi and nvme devices. I have never been good at glob/regex. # by default (built-in), scan all...

It's said even on proxmox documentation itself - you can test out proxmox cluster inside proxmox :). It's not uncommon to have these setups if there are some dev machines or migration clones from real world servers. I sometimes make test upgrade/reinstallation on proxmox and then dump the...

Under /etc/pve/qemu-server there are configs for vm's. If you want to change the id you can rename the files. root@phoenix:/etc/pve/qemu-server# ls -ll total 25 -rw-r----- 1 root www-data 392 Feb 22 01:39 1001.conf -rw-r----- 1 root www-data 445 Feb 22 01:39 1002.conf -rw-r----- 1 root www-data...

I believe you just described proxmox recommended way of doing it. Yes - you can backup and then restore to different ID. You can also clone the current vm and this way you get new clone with new id and can delete old one (if you have storage space). As a last resort you can edit .conf files to...

I have a trouble where mdadm autoactivates zfs volumes from VM's. I would not like mdadm to touch anything from zfs volumes. I tried to search for it since it's more like debian problem, but could not filnd a solution. Probably a filter when loading mdadm module? root@elite:~# cat /proc/mdstat...

It's probably somewhat offtopic but why are we uploading stuff to /tmp to copy them over to some storage later instead of just copying directly to storage. I have hung the proxmox many times because of big image file and not enough room on /tmp folder. Also after uploading it will take...

Live migrating between Xeon(R) CPU D-1541 and AMD EPYC 7401 will randomly crash Centos 8 guest OS. Funny enough, it will not crash straight away. It just freezes guest few minutes after migration has ended. Reset of guest (or stop-start) will reboot and fix it. It won't crash openwrt 21.02.

AFAIk the leds only blink (activity) and will not show "dead" disks, because now it's HBA and does not monitor your disk statuses. You might still be able to call identify , but that's about it. You get led action at all? even for disk read-write? Was just hit reply then found this...

I depends how you have this set up. If it's in private network then I would make a simple tcp listener that will use proxmox api to check if machine is alive already. if not then it would trigger the guest startup using pve api. If machine is already in running state then it would just pass tcp...
