Description

Using "fallocate -l <size> <file>" to allocate space to <file> does not increase the quota usage for the affected user/group/project:

# lfs quota -u 1000 /mnt/testfs
Disk quotas for usr 1000 (uid 1000):
     Filesystem  kbytes   quota   limit   grace   files   quota   limit   grace
    /mnt/testfs  102408       0       0       -       3       0       0       -
# lfs quota -g 1000 /mnt/testfs
Disk quotas for grp 1000 (gid 1000):
     Filesystem  kbytes   quota   limit   grace   files   quota   limit   grace
    /mnt/testfs  102408       0       0       -       3       0       0       -
# lfs quota -p 1000 /mnt/testfs
Disk quotas for prj 1000 (pid 1000):
     Filesystem  kbytes   quota   limit   grace   files   quota   limit   grace
    /mnt/testfs  102408       0  204800       -       3       0   10000       -

# fallocate -l 50M /mnt/testfs/projdir/50M
# lfs quota -u 1000 /mnt/testfs
Disk quotas for usr 1000 (uid 1000):
     Filesystem  kbytes   quota   limit   grace   files   quota   limit   grace
    /mnt/testfs  102408       0       0       -       4       0       0       -
# lfs quota -g 1000 /mnt/testfs
Disk quotas for grp 1000 (gid 1000):
     Filesystem  kbytes   quota   limit   grace   files   quota   limit   grace
    /mnt/testfs  102408       0       0       -       4       0       0       -
# lfs quota -p 1000 /mnt/testfs
Disk quotas for prj 1000 (pid 1000):
     Filesystem  kbytes   quota   limit   grace   files   quota   limit   grace
    /mnt/testfs  102408       0  204800       -       4       0   10000       -

Unmounting and remounting the whole filesystem does not help, I needed to run "e2fsck -fy" on the OSTs in order to update the quota file.
