Thank you, good suggestion, but unfortunately, that does not seem to have fixed the issue.
I did a fresh install, and this is what the disks looked like right after the build:
[root@localhost:~] esxcli storage filesystem list
Mount Point Volume Name UUID Mounted Type Size Free

I disabled the arbitrator:
[root@localhost:~] /etc/init.d/usbarbitrator stop
watchdog-usbarbitrator: Terminating watchdog process with PID 132464
stopping usbarbitrator...
usbarbitrator stopped
[root@localhost:~] chkconfig usbarbitrator off
Then, I tried to upload an ISO to the datastore1. The upload got to about 13%, and then errored out. After that, I get this message:
[root@localhost:~] esxcli storage filesystem list
Cannot open volume:
But, it looks like it still sees the disks:
[root@localhost:~] ls /dev/disks

Any other ideas?
