Package: multipath-tools
Version: 0.4.9+git0.4dfdaf2b-6
Severity: important
Hi,
"multipath -v LEVEL" hangs for me on debian 7 for a fibre-channel SAN.
The command is executet from /etc/init.d/multipath-tools-boot, because of
this the system is completly hanging during boot. I had to fix this with
an live-CD.
You can test it well on a normal command-line. There you kill it with
STRG+C
The command works on a fresh installed debian 7 at a virtual maschine
without any fibre-channel and only local disk /dev/vda (virtio).
If I execute it on a blade where "scsi_transport_fc 39180 1 qla2xxx" is
loaded, then it hang.
But under Debian 6 and Ubuntu 12.04.2 it is running fine.
"multipath -ll" works on all 3 systems, even on Debian 7.
Regards Sebastian
