actually, i don't know what was actualy changed... after few days of tries i found solution: i replaced curl_setopt($ch, CURLOPT_POST, 1); with curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST"); In any case i think, this has to be reviewed by proxmox dev team, as chunked transfer is mandatory of...

hello. i used own php script to connect to PVE. for now auth is ok, but in any post it returns "HTTP/1.1 501 chunked transfer encoding not supportedCache-Control: max-age=0Connection: closeDate: Fri, 12 Jan 2024 16:34:33 GMTPragma: no-cacheServer: pve-api-daemon/3.0Expires: Fri, 12 Jan 2024...

No, i didn't delete node. So now i understood. I have 3 of 5 nodes left and all worked. And now when all of them are working in different places - they all want at least 3 (in my case each other). So. On one node i changed corosync.conf and manually wrote on all other nodes "votes:0". On...

Earlier i tried to rejoin node. Faced with VMs loss. Of course i can archive VM config files and restore them but i thought that there is some easier way. And also one of nodes are down and all work correctly, but why? Cluster now somehow waits for 3 nodes, but waited for 4...

Thanks for your answer. Actually as i said, i don't need to separate node at all. Simply for some time it has to work separately and then return back to normal work. Somehow one node working standalone, but other ones don't want without every time setting "pvecm expected 1". Maybe if i...

Hello. I have faced a problem. I have migrated nodes to different places. And for now i do not need them in a cluster (as i have latency between 2.3 - 4msec it causes troubles) After reboot, every node wants "pvecm expected 1" to start all VMs. How can i fix it? For now i do need any...

Reboot all anodes helped.

Few issues was fixed. but now i have corosync[1356]: [KNET ] rx: Packet rejected from 192.168.7.143:5405 in logs of other nodes. i searched about it. in https://forum.proxmox.com/threads/impossible-to-join-node-after-cluster-is-created.114991/ i saw that problem may be in MTU, so i...

Hello. I had to migrate one node from cluster to a different place. Networks in that places are xombined with gretap. So, i changed node IP from 192.168.1.140 to 192.168.7.140 (as in "remote" networks) On one of nodes that left i changed /etc/pve/corosync.conf - replaced ip of that node and...

Review your overalll network config. Review your IPs, they have to be in the same network. Maybe you have a stuck with your router (if you have) and have only 1Gbps instead of 10Gbps. I have between all VMs and VM - host 10Gbps uplink. I don't know why 10,but actually i have no more than...

Actually, iotop shows "CONFIG_TASK_DELAY_ACCT not enabled in kernel, cannot determine SWAPIN and...." Editing /etc/grub/default with GRUB_CMDLINE_LINUX_DEFAULT="delayacct" fixes this issue. So, maybe have sense to enable it in kernel again? And post and update (or with new kernel)

After tests: 1. Iso have to be written in dd mode in rufus. 2. I don't know if it actually matters, but: Default raid config - works. Custom with cluster size 512kb and larger and 63 sectors - don't work After all of that, i rebuild all raid arrays, and i'm happy. P. S. Tested on R710, R720...

With pve6 i used scheme like this: Call to vncproxy, get port and ticket then call to vncwebproxy?port=port&ticket=ticket Then in php - setcookie('PVEAuthCookie', here the cookie from call to api2/json/access/ticket And opened in browser...

Had a few free time to test) I have same problem with only raid configured. So i used separate ssd for system and 4hdd with raid 10

Do you use UEFI or legacy boot? I have similar with legacy boot. Also, you wrote stick in ISO or dd mode in rufus? P.s. The best choice is to use dd mode in rufus and UEFI in BIOS

Thank for your reply. I found similar answers about caching. Yes, if i create VM on 870qvo and use it with write-back cache the performance is very high. But if i migrate VM to this ssd the performance is very slow after 20-40Gb of transfer. But after about 20mins the performance of working...

On windows tests was simple. Copy/paste, move from other ssd, crystaldismmark with changed options like bs=4k (bs=128k), queues=1,3,8,filesize = 30Gb, 20k files (in folder) by 3-8k each. On linux (tried on PVE, debian 10,ubuntu 18.04) dd, fio (like upper in posts) - same results approx 2-5Mb...

Hello. I faced the similar problem with 870 QVO 1Tb. I tested on LVM thin, directory configs... Proxmox 6.4 latest. Results: Sequential, random reads - 520-550Mbps Seuqential, random writes - 78-81Mbps. And there is no matter that is sequential or random... Tried this ssd on windows machine -...

I tried with LVM, LVM-thin (the most i use) storage and simple directory (qcow2) No, with proxmox 7 i didn't try. I have this issue from old proxmox 5... I googled about high IO delay but there is a lot of threads but nothing about that...

Hello. I have troubles with live migration if "discard=on" for VM. For some time it halts overall system with IO delay 90% and then migration starts normally. it seems that proxmox at first moving something (the whole disk size), i can see it by network monitor, and than move disk as usual. I...
