Proxmox looses SMB/CIFS connection

Since the latest proxmox update my host is loosing the SMB/CIFS connection to the share with my Vm images. That does instantly freeze all vms running from this share. The storage is provided by TrueNas scale (latest version) which is running stable. The connection between the systems is a 20 Gbit/s LAG group. The proxmox version is: Virtual Environment 7.2-4

How can i fix this issue?

hi,

which kernel version are you running? check with uname -r or pveversion commands.

you can also test if it helps to pin to an older kernel version and let us know here if it works
 
Thanks for the reply!

Thats my current version:
Code: 
root@pve1:~# pveversion
pve-manager/7.2-4/ca9d43cc (running kernel: 5.15.35-1-pve)

I am not sure how to select/pin the system to an older kernel version. Is there an option in the GUI, or has it to be done via the command line?

The VM was able to boot and is running "stable" for ~60 minutes now. So changing the kernel did improve the situation. Thank you! Will this issue with the kernel be fixed in the next release?

Edit: The performance issues i mentioned (now removed) were caused by the missing host cpu flag on the TrueNas VM. I dont know why it got lost, but now its working fine.

Code:

+1, I just upgraded and have had huge CIFS issues. Downgraded Kernel thanks to this post and have been solid.

Looking, there were some deprecated security protocols in 5.15, perhaps related?

+1, I also upgraded and it broke all my network-mounted VMs.

Code:

Pinned to version 5.13.19-6-pve and problem went away.
 
Still the same issue with the latest version:
Code: 
root@pve1:~# pveversion
pve-manager/7.2-7/d0dd0e85 (running kernel: 5.15.39-3-pve)

Is there any ETA for a fix?
 
I had this same problem on a fresh install of proxmox and had no previous kernel to pin to.

Thank you very much for the reply! I switched the mode a few days ago and confirm that its working fine now.

Life saver! Thanks for this tip!
 
Hi everyone, I transferred a vm from an old installation of pve 6.4-15 to a cluster 7.2-11, the vm has two disks on a smb share and after a while it crashed with the message io error, I tried to change async io on native and now, after 3 hours, it seems to work regularly, I think it is appropriate to investigate the thing because it calls for damage

the issue was already investigated, but unfortunately no solution was found yet when discussing the issue with the kernel developers. For Proxmox VE, I sent a patch now to just disable io_uring for CIFS storages, until the issue can be fixed in the kernel.

Fiona - was there any further movement on this issue? As far as I can see, it more or less prevents VM disk images from being moved to a CIFS share. Reproduces fairly reliably on pve-manager/7.3-3/c3928077 (running kernel: 5.15.74-1-pve). Thanks!

I'm not aware of any upstream fix yet, but if you have qemu-server >= 7.2-6 installed and the disk has not explicitly set Async IO to io_uring (if the setting is default, io_uring will not be used for CIFS), you should not run into the issue.

If you do have different settings and still run into the issue, please share the output of
Code: 
pveversion -v
qm config <ID>
cat /proc/fs/cifs/DebugData
cat /etc/pve/storage.cfg # section for the CIFS share is relevant
and describe the error you are seeing in detail.
 
@fiona thank you for your quick response. I am starting to wonder if what I am observing is this same issue or a related but separate issue. My problems arise when I attempt to move a disk of a live VM from ceph to a CIFS mount. The action fails - sometimes immediately, sometimes after copying some data.

Sorry for the delay. I think the issue is that with an online move disk, our check if io_uring should be disabled isn't done :/ The check happens at startup and sets the appropriate option for the -drive commandline for QEMU. We'd need to tell QEMU to turn it off on the target of the move operation, but I'm not sure if there's a way to do that currently, will need to have a closer look.

EDIT: Created a bug report to keep track of the issue https://bugzilla.proxmox.com/show_bug.cgi?id=4525

Hey Guys,

I actually have the same problem, but not with a VM but with a container. I have also had the problem for some time that "bad crc/signature" messages keep appearing in the Proxmox syslog. This is actually due to the fact that the container mounts various file server shares and then loses them.
