According to your debug log, the ngx_mogilefs module left your
location /share/ and did an internal redirect to an
automatically-generated location named /mogstored_spare_34991976/  or
so (maybe created by the mogilefs_pass directive):

[debug] 7200#0: *1058 internal redirect: "/mogstored_spare_34991976/?"

And you didn't configure ngx_srcache at all in this anonymous location
and hence no srcache_store love here.

AFAIK, the ngx_eval module also does something similar here (i.e.,
creating nested locations automatically).

Just search for "internal redirect" in your debug log above.

Also, you should be careful when using the "if" directive in location
blocks because it also created a nested anonymous location. See the
discussion here:
