Package: multipath-tools
Version: 0.4.8-14+lenny2
Severity: normal
*** Please type your report below this line ***
I have a simple setup with a Promise VTrak E610f direct-connected
to a Dell 2950 with LSI FC949SE card. There is only one FC connection.
Two LUNs are exposed by the Promise.
# multipath -l
mpath1 (2227300015530e20d) dm-1 Promise ,VTrak E610f
[size=13T][features=1 queue_if_no_path][hwhandler=0]
\_ round-robin 0 [prio=0][active]
\_ 0:0:0:1 sdf 8:80 [active][undef]
mpath0 (2228f000155e2acda) dm-0 Promise ,VTrak E610f
[size=13T][features=1 queue_if_no_path][hwhandler=0]
\_ round-robin 0 [prio=0][active]
\_ 0:0:0:0 sda 8:0 [active][undef]
When rebooting, or sometimes doing /etc/init.d/multipath-tools restart,
multipathd segfaults, e.g.
kernel: [ 511.240204] multipathd[6331]: segfault at ffffffff00645a68 ip
7ffe3777ea0e sp 4000fd30 error 4 in libc-2.7.so[7ffe3770b000+14a000]
and another
kernel: [ 1150.730222] multipathd[6379]: segfault at a ip 7f02665569fb sp
7fffffffe0a0 error 4 in libc-2.7.so[7f02664e3000+14a000]
It doesn't occur reliably.
I've tried with and without the /dev/mapper/mpathN-part1 partitions
mounted. I haven't tried restarting/rebooting when under load.
This may be the same bug as 519252. If so, it seems it isn't quite fixed.
I have a system available for testing but it needs to run lenny packages
or lenny-backports in a pinch.
Kind regards
Vince
