       convertquota - convert quota from old file format to new one


       convertquota [ -ug ] -e filesystem

       convertquota [ -ug ] -f oldformat,newformat filesystem


       convertquota  converts old quota files quota.user and to files aquota.user and in new format currently used by 2.4.0-ac? and newer or by  SuSE  or  Red  Hat
       Linux 2.4 kernels on filesystem.

       New  file  format  allows  using  quotas  for 32-bit uids / gids, setting quotas for root,
       accounting used space in bytes (and so allowing use of quotas in ReiserFS) and it is  also
       architecture  independent.  This  format  introduces  Radix  Tree  (a  simple form of tree
       structure) to quota file.


       -u, --user
              convert user quota file. This is the default.

       -g, --group
              convert group quota file.

       -f, --convert-format oldformat,newformat
              convert quota file from oldformat to newformat.

       -e, --convert-endian
              convert vfsv0 file format from big endian to little endian (old kernels had  a  bug
              and did not store quota files in little endian format).

       -V, --version
              print version information.


       aquota.user         new user quota file        new group quota file


       quota(1), setquota(8), edquota(8), quotacheck(8), quotaon(8), repquota(8)
