    Reconstruction user directories

    When the user directory on a module has been corrupted for whatever reason, there are two possible ways to recover it, using utilities included in "fuseMk5".

    If the module was previously imported into DiFX:

    mkdir tmp; cd tmp
    cp -a /cluster/difx/directories/<modulename>.dir .
    /cluster/mark5/fuseMk5/fuseMk5-cvs/difxdirfile2userdir.py  <modulename>.dir  newdir.bin
    /cluster/mark5/fuseMk5/fuseMk5-cvs/fuseMk5 --udread newdir.bin /mnt/diskpack
    ls /mnt/diskpack
    fusermount -u /mnt/diskpack
    /cluster/mark5/fuseMk5/fuseMk5-cvs/writeuserdir newdir.bin
    If only a FieldSystem log file exists:
    mkdir tmp; cd tmp
    cp <fieldsystemlog>.log .
    /cluster/mark5/fuseMk5/fuseMk5-cvs/fslog2scanlist.py <fieldsystemlog>.log  newdir.dir
    /cluster/mark5/fuseMk5/fuseMk5-cvs/text2userdir.py newdir.dir newdir.bin
    /cluster/mark5/fuseMk5/fuseMk5-cvs/fuseMk5 --udread newdir.bin /mnt/diskpack
    ls /mnt/diskpack
    fusermount -u /mnt/diskpack
    /cluster/mark5/fuseMk5/fuseMk5-cvs/writeuserdir newdir.bin
