Hello Sir,

I am currently working on Coda 5.3.20 on Redhat 7.2 for testing purpose. I
am trying design a large and scalable distributed storage system for a
project of my own.

I installed coda server on 2 machines one scm and other non-scm. I
replicated a volume between the scm and non scm server.

For the testing purpose of filling up the total space on both the servers
hard drives, (which is 40 GB) (PS. I have kept rvm size as 315MB), i wrote
a script to copy 10000 files initially on the replicated volume.

After successfully copying around 8000 files, I got an error on client
side as Input/Output error, and the coda server process died on both the
server machines.

On going through the server error logs, if found the following error.

00:33:49 Create returns 27 on coda12_8050.jpg (0x1000003.0x7454.0x201f)
Assertion failed: 0, file
"/usr/src/redhat/BUILD/coda-5.3.20/coda-src/vice/", line 4117

While searching the coda mailing list i came upon the following threads,

which was also confirmed in the following article

Also note that I did not create any sub directories in my replicated
volume, and started copying files directly.

Now I have the following doubts and questions.

1.) What does it really mean by directory size of 256kb? does it mean the
directory can contain information of its contents inside it (sub-dirs or
files) of 256kb characters only?

2.) How should I solve this problem of limited files in a directory? does
it mean I have to create sub directories in the volume to store the files?

Note. In my actual implementation of a distributed storage system in need
to store around 20000000 files of 300 KB size which can be accommodated
easily in 315 MB of RVM.

3.) Is there a work-around for this problem or is this problem solved in
coda 6.0 or above?

with regards,
