Hi Sriram,
I found it. It's my fault. As I restart everything, I checked with ps command to make sure the metaserver is running and discovered that there are two metaserver processes are running :D. I killed them all and restart. It's work now (with the source code compilation, not the binaries copied)
Thank you very much again for your patience.
TT

Hi Tung,

Can you put the cluster key in the chunkserver.prp file and restart everything?  Also, please include the .prp file from the chunkserver as well (in the next mail).

This is very odd...

Can you run without the cluster key in the chunkserver config?  Also, what is the cluster key in the metaserver's config?

Sriram,
I got the followings in the logs dir. I hope this helps. However, the cluster key of the chunkserver and metaserver are the same.

Hi Tung,
 
Can you load the core into gdb and get me a backtrace?
 
Thanks.

Hi,
I would like to install KFS on a cluster that has chunkservers running in Centos and metaserver running in Ubuntu (our gateway). 

I ran the kfssetup script to distribute binary to the chunkservers but I failed to start the system. I checked the kfsping and there's no chunkserver connecting to the metaserver.

I digged into the chunkserver (CentOS) and modified the kfsrun script to print out the errors. I got:
#scripts/kfsrun.sh -s -c -f bin/ChunkServer.prp
Usage: grep [OPTION]... PATTERN [FILE]...
Try `grep --help' for more information.
Starting chunkserver...
bin/chunkserver: error while loading shared libraries: libcrypto.so.0.9.8: cannot open shared object file: No such file or directory

In Centos /lib or /lib64, I only found libcrypto.so.0.9.8e
so I created symbolic link from  libcrypto.so.0.9.8 to libcrypto.so.0.9.8e and ran it again. I got:
scripts/kfsrun.sh -s -c -f bin/ChunkServer.prp
Usage: grep [OPTION]... PATTERN [FILE]...
Try `grep --help' for more information.

Please let me know what can I do? I also tried to download, compile from source and ran the kfsrun script but I got a core dump
...
