multipath -v3
I'm not sure why the device is trying to load so many times, but it looks like it's failing because the device is in-use. The device that is already in use is /dev/sda. Is this devices supposed to be multipathed. I assume that it is the root device. If so, you will need to remake the initramfs, so that multipath can
access this device before it gets mounted. However, it looks like there is only one path. In this case, I assume that you don't want this device multipathed. In that case, you need to add
blacklist {
wwid "3600508e00000000013574a8cfbafd40c"
}
to /etc/multipath.conf
this will keep multipath from trying to use this device.
Is this still an issue for you? No, i have fixed this with a manual blacklist configuration. But this can be a problem for other people, that install this automaticaly over the rhev-m gui. I change the status to low. So, multipath seems to be acting as designed. If have a multipath configuration file, and you do not blacklist a device, it is assumed to be whitelisted. This bug should either be closed NOTABUG, or it should get moved to the rhev-m gui, which should handle dealing with the configuration file. |
