Thanks to everyone for their responses.
Looks like building the /dev tree was not the problem.
The ram size was the problem.
I kept reducing the size from 96MB in the dd command and it finally worked
at 16MB.
Worked:
=======
dd if=/dev/zero of=/dev1/dev/ram1 bs=1024 count=16000
16000+0 records in
16000+0 records out
dd if=/dev/zero of=/dev1/dev/ram1 bs=1024 count=16384
16384+0 records in
16384+0 records out
Fails if count is 16385 or greater:
=====================================
dd if=/dev/zero of=/dev1/dev/ram1 bs=1024 count=16385
dd: writing `/dev1/dev/ram1': No space left on device
16385+0 records in
16384+0 records out
Questions:
1. How can I check the ramsize? (I am on RHEL 4)
2. How can I increase it to be 96MB?
3. Should I post this as a new thread?
Thanks!
