[Solved] Samba panic on folder access

Post by PolluxAndCastor » 2018/10/05 15:04:09

Hello,

I'm faced with an issue that I tried to solve myself for some time, but i'm now totally clueless, hence requesting your help.

I have a Samba4 running on a CentOS 7 server.
From Windows 10 client, it's working great (except I'm seeing some core dumps from time to time), I can authenticate and access to the server and browse the shared folder.

The problem appears when accessing a folder from any MacOS client, the Samba server enters a Panic loop, and I have to kill it before the coredumps fill my /var partition.
From such client, I can authenticate to the server, and see the folders inside the share, but as soon as I enter a folder, the issue occur.

These are the system details :

Code: Select all

# uname -r
3.10.0-862.11.6.el7.x86_64
# rpm -q samba
samba-4.7.1-9.el7_5.x86_64

Code: Select all

# testparm -s
Load smb config files from /etc/samba/smb.conf
...
vfs objects = aio_linux acl_xattr snapper btrfs
...
(..trunc)

Any help would be greatly appreciated.
Thanks

Hello again.
Okay, I've got it sorted thanks to the samba ML.
The panic culprit was the 'aio_linux' vfs module.
This led to a legacy file from the conf.d folder, and once removed, everything is working perfectly.
