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 increased
after the current reservation is exhausted.
Reservations and fixed extent sizes are allocated in units
of the file system block size.
The
align
and
noextend
allocation flags
(set through
setext
or the
VX_SETEXT
ioctl)
are persistent attributes of the file and can be displayed using
getext
or the
VX_GETEXT
ioctl.
trim
can also be displayed,
although it is cleared and the reservation
is reduced after the final reference to the file.
