#9087 cifs mounts fails with error: cifs filesystem not supported by the system

Closed: fixed 2 years ago by frenaud. Opened 2 years ago by sumenon.

Issue

cifs mounts fails with error: cifs filesystem not supported by the system

Steps to Reproduce

Tests in test_smb.py fail

Actual behavior

DEBUG    ipatests.pytest_ipa.integration.host.Host.client0.cmd161:transport.py:513 RUN ['mount', '-t', 'cifs', '//client1.ipa.test/homes', '/mnt/smb', '-o', 'user=user1@IPA.TEST,pass=SecretUser1']
DEBUG    ipatests.pytest_ipa.integration.host.Host.client0.cmd161:transport.py:557 mount error: cifs filesystem not supported by the system
DEBUG    ipatests.pytest_ipa.integration.host.Host.client0.cmd161:transport.py:557 mount error(19): No such device
DEBUG    ipatests.pytest_ipa.integration.host.Host.client0.cmd161:transport.py:557 Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) and kernel log messages (dmesg)
DEBUG    ipatests.pytest_ipa.integration.host.Host.client0.cmd161:transport.py:217 Exit code: 32

Expected behavior

cifs mount should work

Same failure seen in testing_master_latest PR 1440 report

abbra commented 2 years ago

This looks like a kernel issue in the images we use. Can you try to run that image locally and reproduce:

# modinfo cifs
# modprobe cifs

abbra commented 2 years ago

I have no problem for cifs.ko on 5.14.14 kernel on F34.

The image is missing the cifs module.

@abiagion could you check if a rebuild of the image is needed? Same problem is seen on master-latest, master-previous, ipa-4-9-latest and ipa-4-9-previous

I think this commit in Fedora kernel broke it in November 2021: https://src.fedoraproject.org/rpms/kernel/c/c2b24705e7bef009ee3bf63ebcfa111b92996936?branch=f35.

This means it is now part of kernel-modules subpackage.
