The next thing I would try is "erase" the flash memory. If that doesn't work, there is a reference on the Cisco website that for 2600 and 3600 routers that a filesystem has to be squeezed once before use (I assume before copying files to it). Mine has always worked, so I don't know if this also applies to Dynagen, but: The CCO article imples that one needs to: 1. erase flash 2. squeeze 3. copy files 4. delete a file 5. squeeze My preferred option would be up the flash drive in the definition, so “disk0 = 256? gives you

Here’s what I got:

% not enough space on flash to store vlan database. trying squeeze…First creat
e squeeze log by erasing the entire device

% error squeezing flash – (Missing or corrupted log)
