hi sir,
i have a small problem in enabling quotas on my
system, following is the description of what i did :
1. edited /etc/fstab and given usrquota and grpquota
for root fs.
2. made aquota.user and aquota.grp with 'quotacheck'.
3. used 'edquota' to manupulate quotas for a user say
'pankaj'.
This is working fine ..
but i do'nt want to use edquota (according to my
requirement) .. i tried to use 'quotactl' to
manupulate quotas , things related to quotas in my
code are :
------
#include<linux/quota.h>
main()
{
strcut mem_dqblk quota;
if(quotactl(Q_GETQUOTA,"/dev/hda7",502,"a)<0)
{
// here it is giving errno = 22 ( EINVAL)
exit(0);
}
.....
}
----
also note :
1. /dev/hda7 is device on which i have my root fs.
2. 502 is valid user.
3. kernel is compiled with CONFIG_QUOTA set .
so , quotactl is returning with err code 22 (EINVAL)..
plz tell me why it is failing ..
OR is there is any method by which i can give
alternate file (in which we have quotas defined for
users) in 'edquota' , i want that edquota shud read
quota limits from my file..
PLZ reply soon ..
Rgds,
Pankaj
