Example of proper settings for 250 GB, no limit of files (admin2 is my dev account):
quota -u admin2
Disk quotas for user admin2 (uid 2474):
Filesystem blocks quota limit grace files quota limit grace
/dev/md2 40 262144000 262144000 1667 1000000 1000000
/dev/md3 112 262144000 262144000 28 1000000 1000000
/dev/md4 126956108 262144000 262144000 1780351 0 0
your settings shows 25 GB and about 10 mln files which is way too high (should be max. about 2 mln or user set):
