:oops: Rocky 8 and Debian 12 on the same host, with same parameters,same underlining hardware, same virtio drivers and so on ?

Maybe you have slow acces to this NFS share ? You can send the results of : time /usr/sbin/rpcinfo -T tcp 10.88.90.38 nfs 4 time /sbin/showmount --exports 10.88.90.38 time ls /mnt/pve/mnt/pve/tintri1638 nfs4

Did you reboot it ?

Hello. My point of view : - Using remote CEPH is a bad idea form me as this will lead to catastrophic performance. - Using remote 5 nodes cluster for quorum votes is good only if : - your internet link is always up (if not, you won't be able to operate the local nodes) - latency between all...

Yes ! I forgot this ! Thank you to have spotted that. So @sherrellbc shall wait for the Ubuntu 25.04 that will use Linux kernel 6.14 by default it seems (source : https://www.omgubuntu.co.uk/2024/11/linux-kernel-6-12-has-landed-and-its-a-big-one)

Like @UdoB said, it is OK. I do almost what you did for a NextCloud VM. @louie1961 what is not optimal for you could be optimal for someone else. For example for simplicity, robustness, integration. Personally I like to have Proxmox Virtual Environment dumb and complete backup, knowing that all...

Personally I test thing after thing. For example iperf3 -F test network bandwidth + file access + potentially VM OS cache , VM FS cache, host OS cache, RAID card cache, disk cache, ... For disks I use : https://wiki.liberasys.com/doku.php?id=diskwipetests:disks_wipe_and_tests&s[]=test For...

6.12 kernel will come with Debian Trixie (see : https://packages.debian.org/testing/kernel/). Proxmox may integrate it before Trixie release. We just have to wait. Or you can try kernel compilation ;)

I do not have enough elements to help you to take a decision and we are in a community forum. I take time for free here to help people. I won't assure anything and I think you can understand. I've only checked the recommendations (see...

- so not following good practices - so not following good practices - ️ - I sell mostly basic subscription. You do not need a lot of tickets. Proxmox Virtual Environment is very stable. But you need good Linux admin skills.

@usridzero : And when you have the problem, you are not doing any backup and there is no special IO waits on the OS disk ? Although you might think that CPU bug is not related to your experience with changing kernel, it might be correlated. You never know how the kernel manage CPU timings or...

Glad to have helped ️

Helllo Cairo. - so all networks goes thru only one physical link ? - so OS is on the same disk as LXCs - because swapping is slow and slows down the whole system (I put swapiness to 0 or 1 and monitor swap usage in big clusters) - look at details here, you have several levels of subscription...

Big blocksize, not really... 2 and 4 disk blocks (see https://unix.stackexchange.com/questions/178899/optimizing-logical-sector-size-for-physical-sector-size-4096-hdd). Can you explain the condition of your two tests ?

@bbgeek17 : private message sent :) @Pigi_102 : glad to have helped ️

Hello, it seems to be a classical resource starvation case. In order to avoid this, you should follow the best practices : - admin network, data network (iSCSI, NFS, backups) and VMs network should be physically separated - OS disk should not be the same as VMs disks - you should not come to a...

What are you fio parameters ? Did you check the different cache usages ? You can look at my procedure here, maybe this would help : https://wiki.liberasys.com/doku.php?id=diskwipetests:disks_wipe_and_tests

Can you list the content of the NFS for example ? And in how many time is it done ? time ls /mnt/pve/SynologyNFS

Yes, I edited my post :) Ok, I didn't remerber that ;) Do you work at blockbridge ?

@bbgeek17 : yes, normally you should use pvresize, then vgextend (and then lvextend bot Proxmox Virtual Environment will manage it from GUI))
