Checking disk usage from the Crossbeam CLI
The command show disk-usage can be used to display disk utilization on the CPM:
CBS# show disk-usage

/dev/drbd2 2011792 37796 1871804 2% /mgmt On XOS version 9.6.0 or higher, a new command,
show statistics is implemented. The following example shows disk utilization for the first CPM:
CBS# show statistics table disk-utilization source cp1
--------------------------------------------------------------------------------
File
Slot Module Vap System Mount Type Size Free Used %
==== ====== === ========== ========= ==== ==== ==== ==== ====
13 cp1 - /dev/sda7 / ext3 12G 0 12G 100%
13 cp1 - /dev/sda1 /boot ext3 101M 88M 7.8M 9%
13 cp1 - /dev/drbd0 /cbconfig ext3 1.9G 1.7G 129M 8%
13 cp1 - /dev/drbd1 /tftpboot ext3 36G 8.7G 26G 75%
13 cp1 - /dev/drbd2 /mgmt ext3 2.0G 1.8G 37M 2%
--------------------------------------------------------------------------------
This command can also be used to display utilization of local APM hard drives when changing the
source parameter. Another option is to use the
verbose parameter to change the output format.
Checking disk usage from the Linux shell
The standard UNIX df command prints utilization of mounted filesystems. When executed with the -h parameter, the sizes in the output are in human-readable format (e.g., 1K, 234M, or 2G).
Filesystem Size Used Avail Use% Mounted on
/dev/sda7 12G 12G 0 100% /
/dev/sda1 101M 7.8M 88M 9% /boot
none 1.8G 0 1.8G 0% /dev/shm
/dev/drbd0 1.9G 129M 1.7G 8% /cbconfig
/dev/drbd1 36G 26G 8.7G 75% /tftpboot
/dev/drbd2 2.0G 37M 1.8G 2% /mgmt

Another way to check disk utilization from the Linux shell is the
/crossbeam/bin/cbs_disk_usage command. Output from this command is similar to the output of the
show disk-usage CLI command. Additionally, it prints the largest files on the filesystem.
Checking disk usage from GEM From GEM, disk utilization can be observed in the CPMs view.
