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 struc‐ ture) 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.
