I'm running Redhat 6.6 and experienced a power failure over the holiday weekend.  The / partition is showing 100% full. How do I check to see which files are actually causing the overusage?[root@sms1 ~]# df -HFilesystem            Size  Used Avail Use% Mounted on/dev/mapper/vg_sms1-lv_root                       53G   51G     0 100% /tmpfs                  34G     0   34G   0% /dev/shm

du -sh * from / will give you the top level directory using the most space, but it might not be very quick.Once you have a good candidate, you can change into that directory, and do another du -sh * to see which has the most content, and drill down.Or, you could use find and specify a file size if you think it's one big file that's causing the issue.  This command finds all files over 500MB starting in / and working down the full directory tree.find / -type f -size +500000k -exec ls -lh {} \;
