Configuring PVFS on Obsidian
following instructions from the appendix in http://www.scalablesys.com/training/1-4-RocksAdmin.swf
- ensure /pvfs-meta exists
on frontend run "mkmgrconf"
The inputs i used:
/pvfs-meta
root
root
777
frontend-0
3000
comp-pvfs-0-0, comp-pvfs-0-1, comp-pvfs-0-2, comp-pvfs-0-3, comp-pvfs-0-4
7000on the frontend run "/etc/init.d/mgr restart"
This spat out errors:
Stopping PVFS daemon: FAILED
Starting PVFS daemon: Coult not setup device /dev/pvfsd
(pvfsd.c, 684): Did you remember to load the pvfs module?
(pvfsd.c, 453): pvfsd: setup_pvfsdev() failedI then ran "/sbin/lsmod" and there was no pvfs module so i attempted "/sbin/insmod pvfs"
This spat out the same errors as before
BUT - performing a "ps aux |grep mgr" revealed that a /usr/sbin/mgr process was indeed running
According to https://lists.sdsc.edu/pipermail/npaci-rocks-discussion/2004-January/004195.html it looks like there are issues with the PVFS kernel module and the Opterons running rocks 3.1<
