Description

Starting in LMI 6.2.1 the /var/ directory is now a separate mountpoint and is configured as a bind mount on /tmp. In addition, the llllv_tmp logical volume has been renamed to lllv_var. As a result of these changes the df output will look like this:

Logapp root:/loglogic 0$ df -h
Filesystem            Size  Used Avail Use% Mounted on
devtmpfs              7.9G  192K  7.9G   1% /dev
tmpfs                 7.9G     0  7.9G   0% /dev/shm
/dev/sda1             5.8G  1.5G  4.1G  27% /
/dev/sda2             5.8G   12M  5.5G   1% /failsafe
/dev/mapper/llvg-lllv_var
                      4.8G   81M  4.5G   2% /var
/dev/mapper/llvg-lllv_db
                      466G  3.3G  462G   1% /loglogic
/dev/mapper/llvg-lllv_var
                      4.8G   81M  4.5G   2% /tmp
/dev/mapper/llvg-lllv_var
                      4.8G   81M  4.5G   2% /tmp
none                  802M  4.0K  802M   1% /loglogic/data/dbi


Although lllv_var logical volume is listed 3 times this is normal and is a result of it being mounted on /var and the bind mount to /tmp. A known Linux issue causes that bind mount to be listed twice so the output is to be expected based on all that information.

Note that the size of /tmp is 4.8GB on a new installation but is about 1GB in size on upgraded systems.

Issue/Introduction

The logical volumes and mountpoints have changed in LMI 6.2.1. This article explains how these changes affect the output of the df command.
