rootcanal

Utility to make dealing with .root files less painful

Usage: ./rootcanal -l

or

./rootcanal -f <file with lfns>

hdfsscan

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>
