Photos must quit because the photo library has become unavailable or its data is corrupt

Question

Hello,
As many of you, I've installed photos. This is my problem: I am an enthusiastic photographer that keeps around 10K photos per year (approx. 60GB), and while I have several years of pictures, I've just get the last 5 years. To be honest, I never liked iphoto to organize my pictures, I rather use Picasa. The way how pictures get organized, the poor effects tweaks to photos, the lack of freedom to keep an online folder...etc.
But with this new Photos, well, what the heck let's give it a chance.
It seemed cool, all my devices connected, iCloud (very limited storage though), new nice quick effects... the organization of pictures also seemed improved. the UI as usual with apple apps, pretty neat and clean.
Did I mentioned that I have several hundreds of GB of pictures? Well, a detail, I keep it in my time capsule to have them handy when I need it. With picasa, I just need to ensure that time capsule is waked, and pictures get recognized at once.
With photos, I've tried with 1 year, 10,000 pictures and.... very disappointed, it shutdown every 1 minute saying "Photos must quit because the photo library has become unavailable or its data is corrupt"...
Do I missing something here? is this supposed to be better than iPhoto? Time Capsule is not able to send steady signal to get my library online?

Not sure exactly whats going on with that given how new Photos is. But, Picasa works because differently than Photos because it doesn't use a centralized library. Picasa will just scan the entire computer and reference it in that location. Photos libraries, while sometimes problematic, are superior because as you've experience moving all the content is as simply as moving a single file.
Suggestions I would try:
Make sure Photos is quit. Hold down Command + Option on keyboard and click Photos icon to launch. Keep holding until you get a dialog box about repairing the library.  Proceed with repair.
Move the library, if size permits, to your local HD on the computer and attempt to open and use.
Create a new library by holding Option on keyboard and launching Photos.  Choose to create a new library and make sure it's placed in your ~/Pictures folder. If that works you know its library specific.
Right click on the external drive (also accomplished by holding Control when click), choose get info on the drive.  Bottom of new window expand (if not already) the sharing and permissions section.  Click lock icon and provide administrator password. If available, which it should be if using same drive for a Time Machine backup, check box to ignore permissions.
