       xfsdq, xfsrq - XFS dump and restore quota


       xfsdq [ -g|-u ] [ -f path ] filesystem
       xfsrq [ -g|-u ] xfsdump_quotas


       xfsdq  outputs  a  summary  of  the  disk  quotas for the specified XFS
       filesystem for either all users declared in the local /etc/passwd file,
       or all groups declared in the local /etc/group file.

       The  output  format  exactly matches that produced by the IRIX repquota
       command, given the -e option.  The format contains two lines  for  each
       user/group  -  the  first line contains the filesystem device file, the
       second contains the uid/gid, block soft limit, block hard limit,  inode
       soft limit, and finally the inode hard limit (in that order).

       xfsdump  runs  xfsdq on those filesystems with quota enabled, and sends
       the  output  to  a  file  (standard  output,  by  default)   which   is
       subsequently  stored  on the dump device.  For user quota, this file is
       named xfsdump_quotas, for group quota it is named xfsdump_quotas_group.
       Thus, the primary purpose of xfsdq is to maintain this dump file format
       between  IRIX   and   Linux,   such   that   xfsdump   backups   remain

       xfsrq  is  a  simple  wrapper  around  setquota(8)  which automates the
       restoration of quota information using this xfsdump_quotas file.

       The -f option specifies the file to which xfsdq will write.  This  file
       must not already exist (it is created by xfsdq).

       The  -u (user) option specifies user quota should be reported.  This is
       the default.

       The -g (group) option specifies that group quota are to be reported.

       The filesystem argument should be the filesystem mount point,  and  not
       the device.


       In  order to restore quota information using the output from xfsdq, one
       must first restore a copy of the  xfsdump_quotas  file  from  the  dump

       On Linux, user quota can then be restored using:

               # xfsrq -u xfsdump_quotas

       On IRIX, the equivalent command is:

               # edquota -i xfsdump_quotas


       Only  user quota are supported by both Linux and IRIX.  Group quota are
       not supported on IRIX and project quota are not supported on Linux.

       The soft and hard block limits reported by xfsdq are in  units  of  512
       bytes  for  compatibility  with  IRIX.  The Linux quota utilities, e.g.
       quota(1) and repquota(8), report blocks in units of 1024 bytes -  xfsrq
       performs the necessary conversions automatically.


       /etc/mtab           default filesystems
