I have a Cisco 3750G stack with 2 members, both WS-C3750G-24TS-E. IOS in use is 12.2(40)SE.
When trying to "copy run start" or "wr mem" I get the following errors:
3750STACK#copy run start
Destination filename [startup-config]?
nv_done: unable to open "flash:/config.text.new"
nv_done: unable to open "flash:/private-config.text.new"
nv_done: unable to open "flash:/multiple-fs.new"[OK]
There is plenty of free space on the flash - I have checked on each member switch. Is this a bug in this IOS version?
