The "HDFS-RAID" page has been changed by PatrickKling. The comment on this change is: Added RaidFSCK instructions.. http://wiki.apache.org/hadoop/HDFS-RAID?action=diff&rev1=6&rev2=7 -------------------------------------------------- === RaidShell === - (currently under development) - The RaidShell is a tool that allows the administrator to maintain and inspect a DRFS. It supports commands for manually triggering the recomputation of bad data blocks and also allows the administrator to display a list of irrecoverable files (i.e., files for which too many data or parity blocks have been lost). + + To validate the integrity of a file system, run RaidFSCK as follows: + {{{ + $HADOOP_HOME/bin/hadoop org.apache.hadoop.raid.RaidShell -fsck [path] + }}} + + This will print a list of corrupt files (i.e., files which have lost too many + blocks and can no longer be fixed by Raid). + === ErasureCode ===
