All About cPanel CIFS-mounted backup drive error

An error while attempting to take a backup of a CIFS mounted drive is inevitable in some cases. Fortunately, our Support Engineers have plenty of experience helping our Clients resolve this specific issue. For instance, here is an example fo an error you may face:

/bin/cp: failed to preserve ownership for `': Permission denied /bin/cp: failed to preserve ownership for `': Permission denied

Furthermore, these errors are often caused as a result of missing extended attributes in the Common Internet File System (CIFS)-mounted drive.

How do I fix CIFS-mounted backup drive error?

  1. First, make changes to the /etc/fstab file to ensure that the CIFS-mounted drive includes the user_xattr option. For instance:
    /dev/mapper/centos_centos--7--clone-root /                       xfs     defaults        1 1
    UUID=01c6e08e-bbd1-4046-af48-beaf233746d4 /boot                  xfs     defaults        1 2
    /dev/mapper/centos_centos--7--clone-swap swap                    swap    defaults        0 0
    //192.0.2.0/mybackup /backup cifs user,uid=500,rw,suid,credentials=/root/.cifs,user_xattr 0 0

    In the above example, the IFS mounted drive entry can be seen in the last line. Moreover, the mounted files are owned by the local user and the access credentials of the CIF drive can be found in the /root/.cifs file.

    Our Support Engineers strongly recommend storing the CIF mounted drive’s access credentials is a secure, separate file.

  2. Next, run the command, remount mount to remount the CIFS-mounted drive.
  3. After that, run the command, lsattr /CIFS_mount to add the extended attributes. You need to remember that the extended attributes are not supported if the lsattr /CIFS_mount returns the error:
    Error means not available: lsattr: Inappropriate ioctl for device While reading flags on ...

    It is important to note that any mount that does not support extended attributes will not be able to function with WHM and cPanel backups.
