One of my routers (1751) responds "startup-config file open failed (Not enough space)" when typed 'write memory' command. When I checked at the flash I found that there is enogh memory available.
Here are some of the outputs:
Directory of nvram:/
%Error calling getdents for nvram:/ ()
29688 bytes total (28612 bytes free)
Directory of flash:/
1 -rw- 6793680 <no date> c1700-k9o3sy7-mz.122-4.T.bin
5 -rw- 8255 <no date> noa-npl-rtr01
16777216 bytes total (9475248 bytes free)
Please let me know what could be the reason behind it and how to tackle it. I have tried to 'delete nvram' which too ended up saying 'not allowed'.
Thanks and regards,
