Introduction
Use the steps below to resolve CIFS mounted backup drive errors.
If needed, please review our full documentation on this.
Procedure
1. Edit the /etc/fstab file so that the CIFS-mounted drive uses the user_xattr option. Example:
/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
2. Run the remount mount command to remount the CIFS-mounted drive.
3. Run the lsattr /path/to/CIFS-mount command to add the extended attributes.
Important:
The mount does not support extended attributes if the lsattr /CIFS_mount command returns the following error:
Error means not available: lsattr: Inappropriate ioctl for device While reading flags on ...
A mount that does not support extended attributes will not function with cPanel & WHM backups.
