Package: open-iscsi
Version: 2.0.865-1
Severity: normal
When I attempt to run "/etc/init.d/open-iscsi stop" or shut down my
machine, I get an infinite hang in iscsiadm. This may be because my
Dell MD3000i array provides three disks when I've only configured two,
like so:

/dev/sdc and /dev/sdd are what I have configured -- I don't know what
/dev/sde is about, but it's still available during the hang. During
the hang this is what goes to syslog:
Feb 21 22:19:30 localhost kernel: sd 1:0:0:0: [sdc] Synchronizing SCSI cache
Feb 21 22:19:30 localhost kernel: sd 1:0:0:1: [sdd] Synchronizing SCSI cache

Feb 21 22:21:30 localhost kernel: session1: iscsi: session recovery timed out
after 120 secs
... and at that point, the /dev/sde device node still exists, though
/dev/sdc and /dev/sdd don't. strace reveals that the last few things
iscsiadm is doing are these:
socket(PF_FILE, SOCK_STREAM, 0) = 3
connect(3, {sa_family=AF_FILE, [EMAIL PROTECTED], 110) = 0
write(3, "\10\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 4760) =
4760
recvfrom(3, <unfinished ...>
... and that's where it stays.
