Utility to make dealing with .root files less painful
Usage: ./rootcanal -l
or
./rootcanal -f <file with lfns>
Scans through files reading 1 byte every defined blocksize (64MB default) with the intention of forcing a read on every block on disk in an HDFS filesystem.
Can use multiple reader threads ( -t option ) for some performance gains.
Writes list of files with I/O errors to an output file.
Usage:
./hdfsscan -v -t 5 -d <directory to start in>
