getext

NAME

getext - get extent attributes for a VxFS file system

SYNOPSIS

AVAILABILITY

VRTSvxfs

DESCRIPTION

getext displays extent attribute information associated with a set of files.

CLUSTER FILE SYSTEM ISSUES

No cluster issues; command operates the same on cluster file systems.

OPTIONS

-F vxfs

Specifies the VxFS file system type.

-f

Does not print the filename.

-s

Does not print output for files without 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 increased after the current reservation is exhausted. Reservations and fixed extent sizes are allocated in units of the file system block size.

NOTES

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.
