46	Changeset 3900 st_blocks and ZFS problem	Yasar Semih Alev	somebody	"Hi,

stat->st_blocks give wrong filesize information on FreeBSD with ZFS filesystem. Nginx cache max_size exceed and filesystem is full sometime later. I searched the problem and see the changes in 3900  and i changed this;

#define ngx_file_fs_size(sb)     ((sb)->st_blocks * 512) 
to
#define ngx_file_fs_size(sb)     (sb)->st_size

The problem solved with this change but I know this change for filesize precise and I/O operations but ZFS st_blocks very different. I googled and read some discussions about these. May be same problem occur on Solaris with ZFS filesystem.

Thanks.

Kind Regards,,
