NAME
getext (vxfs) — get extent attributes
SYNOPSIS
/usr/sbin/getext
[-F
vxfs]
[-V]
[-f]
[-s]
file...
DESCRIPTION
getext
displays extent attribute information associated with a set
of files.
Options
- -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.
OUTPUT
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.
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.
