# xfs\_info(8)

display XFS filesystem geometry information

## NAME

xfs\_info - display XFS filesystem geometry information

## SYNOPSIS

**xfs\_info** \[ **-t** *mtab* \] \[ *mount-point* \| *block-device* \| *file-image* \]\
 **xfs\_info -V**

## DESCRIPTION

**xfs\_info** displays geometry information about an existing XFS filesystem. The *mount-point* argument is the pathname of a directory where the filesystem is mounted. The *block-device* or *file-image* contain a raw XFS filesystem. The existing contents of the filesystem are undisturbed.

## OPTIONS

- **-t**

  Specifies an alternate mount table file (default is */proc/mounts* if it exists, else */etc/mtab*). This is used when working with filesystems mounted without writing to */etc/mtab* file - refer to [**mount**(8)](/mount/8.md) for further details. This option has no effect with the *block-device* or *file-image* parameters.

- **-V**

  Prints the version number and exits. The *mount-point* argument is not required with **-V**.

## EXAMPLES

Understanding xfs\_info output.

Suppose one has the following "xfs\_info /dev/sda" output:

```
meta-data=/dev/pmem0             isize=512    agcount=8, agsize=5974144 blks
         =                       sectsz=512   attr=2, projid32bit=1
         =                       crc=1        finobt=1, sparse=1, rmapbt=1
         =                       reflink=1
data     =                       bsize=4096   blocks=47793152, imaxpct=25
         =                       sunit=32     swidth=128 blks
naming   =version 2              bsize=4096   ascii-ci=0, ftype=1
log      =internal log           bsize=4096   blocks=23336, version=2
         =                       sectsz=512   sunit=0 blks, lazy-count=1
realtime =none                   extsz=4096   blocks=0, rtextents=0
```

Here, the data section of the output indicates "bsize=4096", meaning the data block size for this filesystem is 4096 bytes. This section also shows "sunit=32 swidth=128 blks", which means the stripe unit is 32\*4096 bytes = 128 kibibytes and the stripe width is 128\*4096 bytes = 512 kibibytes. A single stripe of this filesystem therefore consists of four stripe units (128 blocks / 32 blocks per unit).
