Title:
Mounting SMB shares with vers=3.0 in fstab gives "ioctl error in
smb2_get_dfs_refer rc=-2"
Status in dellserver:
New
Status in linux package in Ubuntu:
Confirmed
Bug description:
Xubuntu 17.10 artful
Kernel: x86_64 Linux 4.13.0-32.35-generic
cifs-utils 2:6.7-1
smbclient 2:4.6.7+dfsg-1ubuntu3.1
Mounting an SMB share with
sec=ntlmssp,vers=3.0,credentials=/home/.smbcredentials,dir_mode=0777,file_mode=0777
in /etc/fstab gives the error: "CIFS VFS: ioctl error in
smb2_get_dfs_refer rc=-2" in dmesg.
Shares mounted this way are readable, but writing data to them (or using
programs such as EasyTAG to write to them) ultimately fails. This bug did not
occur in kernel 4.10. Mounting the share(s) with vers=1.0 does not give the
error, but this is a haphazard fix as SMB v3.0 carries many security features
with it not avaliable in SMB 1.0.
