We have a 15 TB luster volume across 4 OSTs and we recently deleted over 4 million files from it in order to free up the 80 GB MDT/MDS (going from 100% capacity on it to 81%. As a result, after the rm completed, there is significant lag on most file system operations (but fast access once it occurs) even after the two servers that host the targets were rebooted. It seems to clear up for a little while after reboot, but comes back after some time.
Any ideas? For the curious, we host a large image archive (almost 400k images) and do research on processing them. We had a lot of intermediate files that we needed to clean up: http://krauthammerlab.med.yale.edu/imagefinder (currently laggy and unresponsive due to this problem) Thanks, Jim -- Jim McCusker Programmer Analyst Krauthammer Lab, Pathology Informatics Yale School of Medicine [email protected] | (203) 785-6330 http://krauthammerlab.med.yale.edu
