Repository offline with file system I/O DvmFSIO error (4037117)

The repository is offline and shows the following error: 

File system I/O error Error checking the file system: '89472f33-964c-4d77-8fad-de6414a872b6', data path: 'E:\repository', metadata path: 'E:\Repository' - Error(s) 'DvmFSIO' Please, make sure that locations are reachable, and you have all of the required permissions to access it.

When reviewing the repository configuration there is a prompt to fix the problem with the repository.  Clicking fix does not resolve the issue and the same error is presented. 

All repository files are present, and the path is correct, but the repository still doesn't mount.

• Permissions for the volume, folders, and files for the repository are incorrect and that the Local System account has no longer permissions to them
• Antivirus is blocking an access (this is the root cause in most cases). NOTE: Just giving permissions / exclusions in Antivirus is not always enough, sometimes it will be needed to uninstall the Antivirus and reboot to unload the Antivirus filter drivers.
• The repository volume has the 'read only' flag. 

To resolve this issue please verify that:

1. The permissions for the volume, folders, and files for the repository are all correct and that the Local System account has permissions to them.
2. Remove the 'Read Only' flag from the Repository files and folders.
   1. Open File Explorer and locate the Repository folder.
   2. Right click and select Properties
   3. In the General tab, uncheck the 'Read-only" attribute.
3. The volume where the repository is stored is marked as read-only, please take the following steps. 
   1. Open command prompt as Administrator
   2. Enter the commmand "diskpart" to enter the diskpart utility 
   3. In diskpart find which disk the repository is stored on by typing "list disk"
   4. Select the disk the repository is stored on by typing "select disk <disk_number>" 
   5. Show all attributes for that disk by typing "attributes disk"
   6. Check to see if the value Read-only is set to yes
   7. If the disk is marked as Read-only then remove the read-only flag by typing "attributes disk clear readonly"
   8. Exit diskpart by typing "exit"
4. Temporary and for testing only completely uninstall all Antivirus software, the entire software packages. Not just separate module or part of AV software. Some of them is locking repo files and blocking and access to them. Remember to reboot after this to unload the Antivirus filter drivers.
5. Reboot core server and let repository to mount.
