convertquota

CONVERTQUOTA(8) 					      System Manager's Manual						   CONVERTQUOTA(8)

NAME

       convertquota - convert quota from old file format to new one

SYNOPSIS

       convertquota [ -ug ] -e filesystem

       convertquota [ -ug ] -f oldformat,newformat filesystem

DESCRIPTION

       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.

OPTIONS

       -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.

FILES

       aquota.user	   new user quota file

       aquota.group	   new group quota file

SEE ALSO

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