effect of change of mpd preferred path settings

Hello All,

In the output of the command "mpdcontrol -no xlist", I found that, some of the preferred paths are marked as "err". You can see the output below:

Code:

In this output we can see that some of the preferred paths were set to "err". So, those preferred paths were later changed to point to the normal disks.

Will changing of these settings result in any slowdown of the system?
