getext - get extent attributes for a VxFS file system
getext [ -t vxfs ] [ -f ] [ -s ] filename ...
getext displays extent attribute information associated with a set of files.
-f Does not print the filename. -s Does not print output for files without fixed extent sizes or reservations. -t vxfs Specifies the VxFS file system type.
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.
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.
file1: Bsize 1024 Reserve 36 Extent Size 3 align noextend
The align, noextend, and growfile 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 close to the file.
