Root filesystem went to read only after the upgrade from RHEL6 to RHEL7

Solution Verified - Updated -


  • After the upgrade to RHEL 7, the root filesystem stays read-only, and can't be remounted read/write:

    mount -o remount,rw /
    mount: / not mounted or bad option
           In some cases useful info is found in syslog - try
           dmesg | tail or so.


  • RHEL 6 upgrade to RHEL 7
