SMB/CIFS write ends with kernel error

HPulstar · 24. Mai 2022

Hi!

I have upgrade from OMV 5.2 to OMV 6.0 for 3 weeks. It's installed in a VM under Proxmox. All updates are installed (Proxmox & OMV). This installation works for more than 1 year without any problems.

Since yesterday, each time I try to write in a samba share, it ends failing and shares no more accessible. I have to restart OMV. Reading do not raise any problems.

When I look to syslog, I found theses kernel messages:

I have found this bugzilla.

My FS is 65To so it seems to match this problem. But I don't know why it happens out of nothing!

Did someone have any clue to repair this problem?

HPulstar · 24. Mai 2022

It's seems to have disappeared when using windows explorer, replaced by an error with rights (I don't know why, same users, no password change). Perhaps rights problem occurs before the kernel error...

But, when trying to write from another Linux (share mounted in RW), the error comes back.

The root casue is here:

Something is trying to execute data as code (0) ?

HPulstar · 25. Mai 2022

Nothing else than OMV is running (OMV and its plugins) on this VM.

Zoki · 25. Mai 2022

Yes, this is a kernel bug maybe in conjunction with proxmox.

Can you try a differnet kernel version?

HPulstar · 26. Mai 2022

I'll try... I've never done that

Edit: With grub, if i boot with Linux 5.10.0-14-amd64, the problem with the rights (connecting from Windows 10) occurs. But the other Linux VM has no problem to write on the share...

The error on windows:

Code

The login & password are the same as before.

Last edit:

Using the configuration "Send NTLM v.2 response only" on windows corrects the rights problem. And I can write on the share!
