In the Coda file system, why is it sometimes necessary for users to intervene manually in the process of updating the copies of a file at multiple servers?
What will be an ideal response?
Conflicts may be detected between the timestamps of versions of files at a Coda file server and a disconnected workstation when the workstation is reintegrated, Conflicts arise because the versions have diverged, that is, the version on the file server may have been updated by one client and the version on the workstation by another. When such conflicts occur, the version of the file from the workstation is placed in a covolume – an off-line version of the file volume that is awaiting manual processing by a user. The user may either reject the new version, install the new version in preference to the one on the server, or merge the two files using a tool appropriate to the format of the file.
