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, path=@ISCSIADM_ABSTRACT_NAMESPACE}, 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.
