convertquota - Man Page

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 quota.group to files aquota.user and aquota.group 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.
