Drives appear unmounted in swift-recon

Howdy!

I'm trying to get drive information through swift-recon. I'm using sdb1, sdc1, sdd1 and sde1. Unfortunately, Google didn't help much...

Running swift-recon -d outputs

[2013-01-03 02:44:21] Checking disk usage now
-> http://127.0.0.1:6040/recon/diskusage: Error. No drive info available.
-> http://127.0.0.1:6010/recon/diskusage: Error. No drive info available.
-> http://127.0.0.1:6030/recon/diskusage: Error. No drive info available.
-> http://127.0.0.1:6020/recon/diskusage: Error. No drive info available.
No hosts returned valid data.

and swift-recon -u gives me

[2013-01-03 02:44:54] Getting unmounted drives from 4 hosts...
Not mounted: 1 on 127.0.0.1:6020

As an example of what my conf files look like, my object-server 1.conf looks like this:

[DEFAULT]
devices = /mnt/sdb1
mount_check = false
disable_fallocate = true
bind_port = 6010
user = root
log_facility = LOG_LOCAL2
recon_cache_path = /var/cache/swift
eventlet_debug = true

[pipeline:main]
pipeline = recon object-server

[app:object-server]
use = egg:swift#object

[filter:recon]
use = egg:swift#recon

[object-replicator]
vm_test_mode = yes

[object-updater]

[object-auditor]

Many thanks in advance!
