PMFatalErrorDomain error 9901
When I try to change the Service Data volume, I get "PMFatalErrorDomain error 9901".
I'm on Yosemite Server. Any ideas? Google doesn't bring up much on this.
Hello. It's been a little while since you posted this question, were you able to find a solution? Looks like you posted that question on a few other websites too. I had this problem this morning, which had me hitting the interwebs to figure it out for myself. Your post was the only mention I found! My error number was slightly different, but otherwise sounds like a similar issue.
However, I seem to have identified and resolved my issue. The "PM" part of the error seems to be referring to ProfileManager. I noticed right away that ProfileManager was giving me an "error reading settings" message when I highlighted the service in the sidebar. I'm glad I noticed that, because I don't use ProfileManger on this server. Since I don't use the service, I was good with completely resetting the service per this article: OS X Server: How to reset Profile Manager to its original state - Apple Support.
After I followed all the steps and restarted, I was able to switch my Service Data without the error.
Hope that helps!
