lsvol -- list volume attributes
lsvol [-h] [-d] [-c] volume
The lsvol utility displays various attributes and
structures associated with a volume image. If no options are
specified, lsvol displays the volume header of the
The following options are available:
Display volume header.
The volume header identifies critical information about
the CapROS volume, including the native page size, the
locations of the primary and optional secondary division
tables, and the boot flags.
Show division table.
The division table shows the locations on the volume
of the various divisions. The fields in the division
table entry are:
||Starting sector number of the division.
Bounding sector number (i.e. top plus one) of the
||Size of the division in sectors.
||Type of the division (see below).
If the division is of type Object, Log, or
Kernel, a range of OIDs will also be displayed.
For object and kernel divisions, this is the range of
object identifiers contained in the division. For log
divisions, this is the range of log locations contained in
There are several valid division types:
||The division holding the bootstrap code. Always
starts at sector zero.
The division holding the division table. There may
be up to two DivTbl divisions.
A division that holds nodes or pages.
A division that holds the bootable kernel image.
This division is formatted just like an object
division, and the kernel is layed out in consecutive
pages within the division. The kernel division is
mounted by CapROS as an object division.
A division containing space used by the checkpoint
The failstart entry is actually not a division at
all. It provides a means to boot a recovery or startup
application on a system image that does not have a
checkpoint area (at all). This facility exists
primarily to enable bootstrap floppies to go without
a checkpoint area.
Show checkpoint directory.
This option is mostly of use for kernel development.
