TimeMachine backup failure fixed
My TimeMachine backups had been failing recently on all my client systems. All the computers in my house use TimeMachine to back up to a central volume served up by a Mac Mini. I found that my son accidentally renamed the backup volume on the server and my systems wouldn't mount the renamed volume. I changed the name back and things still wouldn't work. No matter what I tried I couldn't mount the backup volume from the client machines. It was odd because screen sharing worked just fine but the volume wouldn't mount. Checking the system console, I found the following error:
7/25/09 4:41:30 PM /System/Library/CoreServices/backupd FSMountServerVolumeSync failed with error: -128 for url: afp://email@example.com/Drobo
Google searches turned up nada. I found a lot of errors related to FSMountServerVolumeSync failed but nothing referring to error -128. So I performed the only action I hadn't tried: rebooting the server. Lo and behold! I could mount the backup volume and all was right with my TimeMachine universe. Most folks may have just rebooted the server but I always attempt to correct things without rebooting. Sure I may have spent more time on the problem than someone willing to take that coward's way out, but in the process I fixed a few more issues I happened to notice lurking in the system log. I think my laptop is happier for the effort and hopefully this post will help those Googling for the dread -128.
