I used to have a old ubuntu 16.04 server machine, that had a cifs mount of a UCS share that worked for years without any problems.
After update to UCS 5 this mount was not working anymore. Mounting was no longer possible. I thought this is due to the old Ubuntu version, maybe some SMB version issues, so I set up a new machine with Ubuntu 20.04 server. The old machine was never part of the UCS domain. The new one is not either.
Everytime I try to mount the share via mount -a I get
mount error(2): No such file or directory Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) and kernel log messages (dmesg)
[ 4912.185746] CIFS: Attempting to mount //fips-server2/share [ 4912.245052] CIFS VFS: \\fips-server2 Send error in SessSetup = -5 [ 4912.245093] CIFS VFS: cifs_mount failed w/return code = -2
I try to mount using fstab. fstab entry is following
//fips-server2/share /media/share cifs credentials=/home/superuser/.smbcredentials,vers=3.0,iocharset=utf8,uid=0,gid=1000 0 0
Until now I have not found somethin that solves this problem. Does the ubuntu machine has to ba part of the domain recently?
I also have some raspberry pis here that are not part of the domain, but can mount shares of the same server without problems. What am I doing wrong?
I would be glad about any help.
