Our PVFS 2.7.1 installation has started behaving strangely. One of the 3 I/O Servers died and had to restart. Along with restarting all of the I/O servers had to restart all of the pvfs2 clients. I noticed the following warning in dmesg. Does this mean our PVFS2 FS is corrupted? Because, until this error as I understand we were able to submit jobs through SGE and they ran okay. Now none of the jobs get started through our SGE. SGE shows they are running bit none of the job process is running. SGE is not a problem because if the users chose to run their job on an NFS scratch it works fine, hassle free. Any thoughts or feedback please? ***************************************************** pvfs2_kill_sb: (WARNING) number of inode allocs (145476) != number of inode deallocs (145475)
2) What is the best way to upgrade pvfs2 from 2.7.1 to 2.8.1 on a production machine? Can I just install the pvfs2 server first and then mount all the clients with the old version of pvfs2-client. This way I can bring down one compute node at a time and upgrade it to the latest version.
