mount(2) system call failed: Operation canceled after upgrading to 7.4.4

[Paul Jähne]

Hello, I updated from BeeGFS 7.3.1 to 7.4.4 and I got a strange Problem. Only one client was unable to mount BeeGFS after the update. The error was:

$ sudo mount /mnt/beegfs
mount: /mnt/beegfs: mount(2) system call failed: Operation canceled.

I looked into dmesg and there was this error:
beegfs: mount(4044977): The config argument 'connDisableAuthentication' is invalid
beegfs: mount(4044977): Configuration error: Initialization of common objects failed. (Log file may provide additional information.)

/var/log/beegfs-client.log doesn't conatin something related to this.

After commenting the line with connDisableAuthentication = false in /etc/begfs/beegfs-client.conf I got the same error when trying to mount beegfs and this message in dmesg:
beegfs: mount(4059882): The config argument 'connTCPRcvBufSize' is invalid

beegfs: mount(4059882): Configuration error: Initialization of common objects failed. (Log file may provide additional information.)

and this message after commenting the line connTCPRcvBufSize = 0

mount(4067453): The config argument 'connUDPRcvBufSize' is invalid
beegfs: mount(4067453): Configuration error: Initialization of common objects failed. (Log file may provide additional information.)
and after commenting the line connUDPRcvBufSize = 0 mounting beegfs works again:
beegfs: mount(4067515): BeeGFS mount ready.

I couldn't find something in the release notes that might have changed with these parameters and it's strange, that it was only a problem on one client as I use Ansible for the configuration, so the files are identical on all clients.

That looks more to an package update problem one the 1 client as the others are working. Rerun your ansible playbook and if you reboot the client do a "sync" before.

Earlier in dmesg there should be a line showing the version of beegfs.ko

Check that beegfs.ko has been upgraded.

If not, modprobe -r beegfs and then upgrade beegfs.ko, then

modprobe beegfs

Thank you for your suggestions!

@Waltar: I resolved it like you said.

@Guan Xin: I couldn't find something regarding beegfs.ko in my dmesg output. Nethertheless, it mitght help me to diagnose some other problem in the future.
