Hi
@fernando-ferraz asked me to proceed with the tests.
I used this /etc/multipath.conf file:
devices {
device {
vendor "SolidFir"
product "SSD SAN"
detect_checker "yes"
}
}
blacklist {
device {
vendor "SolidFir"
product "SSD SAN"
}
}
Without the correction patch I got the same error.
Then I installed the patch 0.7.4 (proposed enabled).
My steps were:
1. Set multipath config
2. Stop multipath-tools service
3. Create a solidfire volume
4. Attach volume to a existent instance
5. Start multipath-tools service
6. run sudo multipath -v6 -ll

This patch seems to fix the issue. Very long names are not a problem and
the checker does not break anymore.
