    1515Tahoe's SFTP frontend includes several workarounds and extensions to make it function correctly with sshfs.
    1616
    17 When writing a file to the Tahoe filesystem, sshfs does not wait for the 'close' request to complete before reporting to the application that the file has been successfully closed (#1059). Therefore, you should not shut down your gateway node immediately after writing files via sshfs, otherwise those files may be lost. It is possible that an upload could fail (due to a network error, lack of storage space, etc.); such failures will not be reported to applications using sshfs. ([http://allmydata.org/trac/tahoe-lafs/raw-attachment/wiki/SftpFrontend/sshfs.c.patch This patch] makes sshfs wait for close requests to complete, but may cause its own compatibility problems; the patch is provided only for testing purposes.)

It is possible that an upload could fail (due to a network error, lack of storage space, etc.); such failures will not be reported to applications using sshfs. This also implies that during the upload, a file could be visible via SFTP but not via the Tahoe WUI, CLI, or FTP frontends.

    1921Some applications may make assumptions that are incompatible with Tahoe. For example, 'flushing' a file does not guarantee that written data is reflected in the Tahoe filesystem, so opening the same file via another handle and attempting to read that data before the original handle is closed will not work.
