I have a mds9509 and when attempting to redirect the output of the "show tech-support" command to either ftp or a local file on the switch, I receive the error: "Write error: No space left on the device".
Bootflash and system resources all look fine:
MDS9509a# show tech-support > ftp: mds9509a_051407.txt
Write error: No space left on the device
PXDC-MDS9509a# dir bootflash:

Any ideas? I can run the show tech-support from Fabric Manager to my ftp server without any problems.
Thanks,

One thing to keep in mind, is that when you run a command through Fabric Manager, it is executed VIA snmp. When you run a command through the CLI it is executed through the command shell.
I was able to replicate what I believe is your problem in the lab by filling up the volatile partition, then running a command that writes to it (show tech).
Delete the some unused files out of your volatile partition, make sure the space is reclaimed, then run your command. You should be fine.
If you find this helpful, please rate it.

Thanks, that was exactly the issue. Once I cleared the volatile directory (there was an old show tech-support that I stored locally) that resolved the problem.

Hi Aran,
The "Write error: No space left on the device" is due to the /volatile area being insufficient size to store the show tech output. We put it in /volatile before it is ftp'd off the MDS. As of 3.1(3) we increased the /volatile size to 40MB which should prevent the error.
It works from FM because FM does not rely on /volatile. FM does a CLI login behind the scene and screen scrapes the show tech output from the telnet data stream.
