Upgrade of Red Hat Enterprise Linux fails if a filesystem is mounted on /XXX

Solution Verified - Updated -

Environment

  • Red Hat Enterprise Linux v7.x

Issue

  • Upgrade of Red Hat Enterprise Linux fails if a filesystem is mounted on /XXX.
  • Upgrade of filesystems package filesystem-*.el7.x86_64 fails if a filesystem is mounted on /XXX.
  • The yum update filesystem package fails with error "error: unpacking of archive failed on file /XXX: cpio: YYY".

Resolution

  • Do not use /mnt as a mount point. Mount points should be at least one directory level beneath /mnt, such as /mnt/mountpoint
  • Unmount the filesystem mounted on the /XXX directory.
    XXX is mounted directory by the system.

Root Cause

The filesystem-*.el7.x86_64 package contains the /mnt directory. Any upgrade that includes this package will error if a filesystem is mounted on /mnt.

The /mnt directory is provided the filesystem package.
The ISO media was mounted on /mnt directory hence the yum update filesystem failed

[root@rhel79 ~]# df -h | grep media
/dev/sr0               4.3G  4.3G     0 100% /media
[root@rhel79 ~]#

or

[root@rhel79 ~]# df -h | grep media
/dev/loop               4.3G  4.3G     0 100% /mnt
[root@rhel79 ~]#
