Hi Guys, new poster here been using proxmox for some 2 years now, i have a 2 node cluster with a qdisk setup on an readynas RN104 iscsi target, i have updated to the latest version of proxmox which seemed to go ok, however i am having issues with my io delay rate using the iscsi i think. Here is my setup,
1 node which connects to iscsi for storage and also has 2 raw vm disks running on it, the other node also connects so i can do failover of the vm from one node to the other or easy migrate using the iscsi as shared storage, i also have a seperate LUN on the same iscsi but a different target used for a qdisk. However since i put the qdisk under a seperate target and lun i am getting really bad io delays, 2 - 4 % when vms are running but if i try to install another to the iscsi target, or if the vm is updating or restarting io jumps to 60% + , this causes severe issues as you can imagine, the old iscsi which was a qnap that died didnt have this issue so its either the readynas thats causing the issue or the qdisk, i keep getting ping timer 5 secs expired on the console also. So my question is can i move the qdisk to another iscsi target altogether and is so how. please be aware im a linux virgin so please be gentle, i am thinking of moving everything of this iscsi and flattening it and redoing the iscsi setup on the readynas, help plz
Thanks
