NAME
getext (vxfs) — get extent attributes
SYNOPSIS
/usr/sbin/getext
[-F
vxfs]
[-V]
[-f]
[-s]
file...
DESCRIPTION
The
getext
command displays extent attribute information associated with a set
of files.
Options
- -F vxfs
Specifies the VxFS file system type.
- -V
Echoes the completed command line, but performs no other action.
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.
OUTPUT
file1: Bsize 1024 Reserve 36 Extent Size 3 align noextend
The above line indicates a file with 36 blocks of reservation,
a fixed extent size of 3 blocks,
all extents aligned to 3 block boundaries,
and the file cannot be extended once the current reservation is exhausted.
In this case,
the file system block size is 1024 bytes.
Reservation and fixed extent sizes are allocated in units of the file
system block size.
NOTES
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.
