getext (vxfs) - get extent attributes
/usr/sbin/getext [-F vxfs] [-V] [-f] [-s] file...
getext displays extent attribute information associated with a set of
-F vxfs Specify the VxFS file system type.
-V Echo the completed command line, but do not
execute the command. The command line is
generated by incorporating the user-specified
options. This option allows the user to verify
the command line.
-f Do not print the filenames for which extent
attributes are displayed.
-s Do not print output for files that do not have
fixed extent sizes or reservations.
The following example shows a file with a block size of 1024 bytes, 36
blocks reserved, a fixed extent size of 3 blocks, and all extents
aligned to 3 block boundaries:
file1: Bsize 1024 Reserve 36 Extent Size 3 align noextend
The file size cannot be extended once the current reservation is
exhausted. Reservations and fixed extent sizes are allocated in units
of the file system block size.
Only the align and noextend allocation flags (set through setext(1M)
or the VX_SETEXT ioctl) are persistent attributes of the file and
therefore visible via getext or the VX_GETEXT ioctl. trim is also
visible, although it is cleared and the reservation is reduced on the
final close of the file.
