It doesn't work for me but uWSGI is stating both dirs configured with check-
static so it's a different issue.
My vassal config:
[uwsgi]
autoload = true
plugins-dir = /usr/lib/uwsgi/plugins
socket = 172.16.200.55:3017

/mfs is a MooseFS filesystem (fuse based) mounted on my node (inside or outside
the chroot, I've tested both). When I request a file that is stored on /mfs I'm
getting this strace output:
curl app1.domain.com/tv/file1.txt
lstat("/mfs", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
lstat("/mfs/tv", 0x7fff6f519be0) = -1 ENOENT (No such file or directory)
lstat("/home", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
lstat("/home/app1", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
lstat("/home/app1/public", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
lstat("/home/app1/public/tv", 0x7fff6f519be0) = -1 ENOENT (No such file or
directory)
root@node1:~# cd /sudoku/app1/mfs/
root@node1:/sudoku/app1/mfs# ls -lh tv/file1.txt
-rw-r--r-- 1 www-data www-data 1,2K 2012-04-27 16:14 tv/file1.txt
If I create /mfs2 dir and copy tv/file2.txt there and add check-static=/mfs2
than I get 200 OK from curl, so it seems that:
1) uWSGI expects that all files are one the same filesystem
or
2) this is MooseFS/fuse issue (?)
