Half a terabyte of images have been lost. OVer 30,000 of them. Everything from September 6th through yesterday. Had I realized just how badly the mirror failed I probably could have saved them. But I told it to rebuild, and whatever images were on the other drive were overwritten by the bad drive.
I'm going to install, very soon, a second file server that will mirror the first file server.
A new keybaord, and some cables.
