File system management restrictions and guidelines

To avoid file system corruption, do not perform the following tasks during file system management:

• Install or remove storage media.

• Perform a master/subordinate switchover.

If you remove a storage medium while a directory or file on the medium is being accessed, the device might not recognize the medium when you reinstall it. To reinstall this kind of storage medium, perform one of the following tasks:

• If you were accessing a directory on the storage medium, change the working directory.

• If you were accessing a file on the storage medium, close the file.

• If another administrator was accessing the storage medium, unmount all file systems on the storage medium.

Make sure a USB disk is not write protected before an operation that requires the write right on the disk.

You cannot access a storage medium that is being partitioned, or a file system that is being formatted or repaired.

Before managing file systems, directories, and files, make sure you know the possible impact.
