# lmdf

Reports free space for Linked Memory Filesystem.

### Synopsis

`lmdf [-k]`

### Description

lmdf displays the amount of disk space occupied on nvram, the amount of used and available space, and how much of the filesystem's total capacity has been used and fragmented. lmdf produces an output similar to the following:

``

    Device Bytes used avail capacity fragment Mounted on ram.3.0 32768
    16408 16040       50%       27%  /nvram

Note: used+avail is less than the amount of space in the filesystem (Bytes|Kbytes); this is due to filesystem overhead. Furthermore, the amount of space available in the filesystem cannot be allocated all to a single file due to fragmentation.

If the filesystem is fragmented, use lmadm to defragment the filesystem. However, if there is no fragmentation (fragment reports 0%), then the available space in its entirety can be allocated to a single file.

If nvram is not mounted, no data are reported.

### Options

-k
  All output data is rounded to 1024 bytes.

### Implementation

Command implemented in V21.
