Hello everyone,
Is there any way to deal with the problem of root handle ownership?
My installation:
MDS+ i/o server
1) SL 5.0 with 2.6.17-CITI_NFS4_ALL-pnfs-1 from
http://www.citi.umich.edu/projects/asci/pnfs/linux/ and PVFS2 1.5.1
2) i/o server: Ubuntu Server 9.04 with 2.6.31-14-server kernel.
PVFS2 1.5.1 (the same version)
1 installation with 1 MDS + 1 i/o configuration works just fine, but as soon
as I add a second node (re-generating configuration, deleting and even
re-formating the storage), I have a small issue while executing pvfs2-ping:
(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
Per-server errors:
Server: tcp://lustre1:3334: Reports ownership of root handle
# 2 handles for server 0
# 0 handles for server 1
File: <Root>
handle = 1048576, type = Directory, server = 0
remaining handles:
Is there (possibly) any way to get a clue on where the problem might be?
(I've been checking whether there's just one server instance running on each
machine).
I know that is irrelevant for PVFS2 2.8.1 at least, but, unfortunately,
1.5.1 seems to be the last (for now) version supporting PVFS-pNFS, so I kind
of have no option, but to stick to it.
Any suggestions?
Thanks,
Andriy
