NAME

fsindex − Print the block index map for a file. 

SYNOPSIS

fsindex -dev device -part partition file1 file2 ...
fsindex -dev device -part partition -inum num1 num2 ...

OPTIONS

−dev deviceThe name of the device file one which the files live.  Typical names are “rsd00” (SCSI hba 0 target 0) and “rxy0” (Xylogics controller 0).  For SCSI disks, the two digits represent the HBA index and the target ID, respectively. 

−part partitionWhere partition is one of ‘a’, ‘b’, ... up to ‘h’.  The device and partition are concatinated to create the complete device name, i.e. “rxy0g”. 

−inumThis option causes the remaining arguments to be interpreted as inode numbers instead of file names. 
 

DESCRIPTION

This dumps out the block indexes of a file.  It is meant as a simple tool for examining the layout of a file on disk.  You can consult a server’s mount table (/hosts/hostname/mount) to determine the device that corresponds to a particular file system. 

EXAMPLES

fsindex -dev rxy0 -part g file1 dir/file2 file3 fsindex -dev rsd00 -part c -inum 53900 4681

BUGS

The syntax for specifying the device is baroque.
