The other 2 PVs (sdc1 and sdd1) are both full. You can't move any data on them with the current configuration. You'll need to free up ~840GB on nicvg before you can do it. The first step would be to shrink the filesystem using the correct utility for the filesystem (you didn't mention the filesystem type). Fortunately you have 1.2TB free on the filesystem so this shouldn't be a problem. Then reduce the size of niclv and you'll be able to move the PEs off of sdb1. -- Garrick Staples, Linux/HPCC Administrator University of Southern California
