Hello, I tried to install pvfs2, version 1.5.1 on a diskless cluster. The
head node is to be both the metadata server as well as the io server. The
clients are nfs mounted to the head node. The underlying database is the
Berkeley 4.5.20. The check of "pvfs2-ping -m /mnt/pvfs2/" is allright.
However, when I tried to do "pvfs2-cp" or "pvfs2-ls", the commands hang.
The /tmp/pvfs2-server.log shows following, only 2 lines cut out of many:
[E 10/11 14:45] TROVE:DBPF:Berkeley DB: keyval_db->get: DB_BUFFER_SMALL:
User memory too small for return value
[E 10/11 14:45] TROVE:DBPF:Berkeley DB: keyval_db->get: DB_BUFFER_SMALL:
User memory too small for return value
....
The database is configured with:
../dist/configure --enable-pthread_api --disable-libtool-lock
--enable-debug
the pvfs2-1.5.1 is configured with:
./configure -with-db=/usr/local/BerkeleyDB.4.5
-with-kernel=/usr/src/kernel-2.6/linux-2.6.17.x86_64
The head node is configured following the instructions in quick-start.pdf.
The cluster is running Fedora 4.
/sbin/lsmod does not show any pvfs2 module.
Thanks in advance for any help,
wenbin.
