There are several partitions on the Steelhead appliance which are writable and can run out of space:
/config: This partition is part of the flash memory and is used for storing the configuration files.
/proxy: This partition is used for the RSP and PFS.
/var: This partition is used for logging, system dumps and process dumps.
When a partition is full, an alarm will be raised and the status of the device will become Degraded:
The command
support show disk
shows the status of the partitions:
Figure 5.191. Output of the command "support show disk"
SH # support show disk Filesystem 1024-blocks Used Available Capacity Mounted on /dev/sdb7 418806 49904 347277 13% /config /dev/sda3 16513448 2769100 12905408 18% /var /dev/disk0p6 56765020 39510668 14370736 74% /proxy
The capacity shows the amount of usage which is used: 0% is empty, 100% is full.
The /config partition is not manageable from the GUI or CLI and Riverbed TAC should be contacted to determine the cause and resolve the issue.
The /proxy partition is used by both PFS and RSP.
If PFS is used and the partition is full, then the amount of data stored on the file server backed by the PFS share has exceeded the threshold.
If RSP is used there are several scenarios:
Check if there are any RSP images, the RSP software or RSP backups which can be removed.
Figure 5.192. Removing an obsolete RSP image
SH # show rsp images image_rbt_rsp_6_0_0_n19.img image_rbt_rsp_6_5_0_n77.img SH # rsp image delete image_rbt_rsp_6_0_0_n19.img SH #
Check if there are any RSP packages, the virtual machines, which can be removed.
Figure 5.193. Removing an obsolete RSP package
SH # show rsp packages FCI_WIN2K3_STD_X32_v3.0.pkg FCI_WIN2K3_STD_X32_v3.1.pkg SH # rsp package delete FCI_WIN2K3_STD_X32_v3.0.pkg SH #
Check if there are any RSP backups which can be removed.

SH # show rsp backups backup-slot3-20120801.tgz backup-slot3-20120802.tgz SH # rsp backups delete backup-slot3-20120801.tgz SH #
The /var partition is used for the logging of services running on the Steelhead appliance, to capture historical statistics of various parts of the Steelhead appliance, to store process dumps, system dumps and tcpdump captures and to keep track of process files.
Check the following things:
Are there any tcpdump captures running? The background tcpdump capture files are not showing up in the GUI under Reports -> Diagnostics -> TCP Dumps but they still use the disk space:
Figure 5.195. Check for running background tcpdump captures
SH # show tcpdump-x Name: ssh-cifs Start Time: 10:48:17 SH # tcpdump-x capture-name ssh-cifs stop SH #
Are there any tcpdump capture files which can be removed?
Figure 5.196. Remove obsolete tcpdump capture files
SH # show files tcpdump SH_primary_csh-cifs.cap SH_lan0_0_csh-cifs.cap SH_wan0_0_csh-cifs.cap SH # file tcpdump delete SH_primary_csh-cifs.cap SH #
Are there any old process dumps which can be removed?
Figure 5.197. Remove obsolete process dumps

Are there any old system dumps which can be removed?

Neural framing statistics logs can be gathered but are never
rotated. In the
sysinfo.txt
they can be found under the
Output of 'find /var/opt ( -name .running -prune ) -o -type f -ls -mount'
:
section as
/var/opt/rbt/neural-stats.
Contact the Riverbed TAC to remove them.
