mount error: cifs filesystem not supported by the system

Post by soportemodemat » 2021/09/09 23:12:23

Hello guys

I am facing a problem trying to mount a cifs share and using the mellanox drivers because of the infiniband cards that I have. Then when I try to mount the cifs share with the command below I get that error shown below:

mount -vvvvvvv -t cifs -o username=user,password=password,vers=2.0 //<ip-ns>/user /media/tmp

mount.cifs kernel mount options: ip=<ip-ns>,unc=\\<ip-ns>\user,vers=2.0,user=soportemodemat,pass=**********
mount error: cifs filesystem not supported by the system
mount error(19): No such device
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) and kernel log messages (dmesg)

I have tried with versions 1.0 and 3.0 too but I got the same error. I can provide the next information for you to give any idea to solve this issue please:

cat /etc/redhat-release
CentOS Linux release 8.4.2105

Quick question: have you installed the cifs-utils package?
dnf info cifs-utils

That appears to show the cifs module supplied by the CentOS kernel has been replaced by one from Mellanox. You'll need to ask them why it doesn't work.
CentOS 6 died in November 2020 - migrate to a new version!

CentOS 5 is dead, do not use it.

Hi TrevorH

Thank you so much. I am sending the same question to Mellanox forums.
