Multipath makes mounting HDDs harder not to mention emergency mode and "device-mapper: table: 253:6: multipath: error getting device There was a discussion about this quite recently [1]; reading this might be inserting, too. The reason for this is the general 'to fit everyone' approach of the default multipath.conf.
I do not have multiple paths to the storage. In my case can i disable Multipath - is there a right way to do it or i have to use black listing? You can blacklist everything, no problem. But you need make some changes to your mulipath.conf. Please just add the lines and do not remove or disable any services:
to the second line (2) in multipath.conf, add # RHEV PRIVATE to keep host-deploy from overwriting the file. Then, somewhere in the file: blacklist { devnode "*" } Then, you need to run: multipath -d -v3 to test (it should now list all devices as blacklisted) and if successful: multipath Effectively blacklisting everything while dm-multipah continues to run. Please note, if you are running oVirt node, you also need to run persist /etc/multipath.conf Also, you have to do this on every host in your data centers naturally.
