I would have never figured it out myself, with my incorrect assumption about what read-only meant. Once I set it to read-write, it started reshaping again. I'd guess you probably don't run into this issue very often, but it might be useful to others to have this information in the man-page somewhere. Just a line almost exactly like what you've written above could be useful -- "Arrays will not reshape or rebuild if they are in read-only mode. Use the --readwrite switch to set the array to read-write mode to continue a reshape or rebuild." Thanks again, -- Colin Snover http://www.zetafleet.com
