I followed this thread to do the conversion:
Upgrading from PVFS2 1.4.0 to 2.7.0
http://www.beowulf-underground.org/pipermail/pvfs2-users/2008-April/002373.html
When issuing the following:
sudo pvfs2-migrate-collection --all /etc/pvfs2-fs.conf
Error: unknown collection version: 0.1.5
for fs: pvfs2-fs (34ac5fcb)
pvfs2-ping -m /pvfs2 also isn't correct, it suffers the same as
mentioned in mail from:
http://www.beowulf-underground.org/pipermail/pvfs2-users/2008-July/002504.html
with title:
The PVFS2 says"Failure: check root handle failed"
<snip>
(7) Verifying that root handle is owned by one server...
Root handle: 1048576
Failure: check root handle failed
PVFS_mgmt_setparam_all: Detailed per-server errors are available (error
class: 0)
Exactly one server must own the root handle.
In this setup, no servers own the root handle.
