Hi,
I wonder if it is possible to run both MDS and DS on one machine under
usual circumstances. I tried to install both of them on one machine with
Debian Etch but I can't make them work.
I use the following configuration in /etc/exports:
/pnfs
xxx.yyy.zzz.44(rw,fsid=0,no_root_squash,sync,no_subtree_check)
/pnfs
aaa.bbb.ccc.74(rw,fsid=0,no_root_squash,sync,no_subtree_check)
/pnfs/storage xxx.yyy.zzz.44(rw,no_root_squash,sync,no_subtree_check)
/pnfs/storage aaa.bbb.ccc.74(rw,no_root_squash,sync,no_subtree_check)
/pnfs/export aaa.bbb.ccc.74(rw,no_root_squash,sync,no_subtree_check,pnfs)
and /etc/spnfsd.conf:
[General]
Verbosity = 1
Stripe-size = 8192
Dense-striping = 0
Pipefs-Directory = /var/lib/nfs/rpc_pipefs
DS-Mount-Directory = /spnfs
[DataServers]
NumDS = 1
DS1_IP = xxx.yyy.zzz.44
DS1_PORT = 2049
DS1_ROOT = /storage
DS1_ID = 1
After mounting the pNFS export from the client (different machine) it
doesn't use nfs file layout (I have spnfsd running on the server and
nfslayoutdriver loaded on the client). When I try to create a file in
the mounted directory (e. g. echo aaa>/mnt/testfile), I can't get any
response, it just hangs (sometimes terminating it by ^C works, sometimes
not). The file is created on the server, but is empty. I thought it
could be related to running portmap but even if I run rpcbind instead of
portmap, the problem doesn't disappear). Is there any problem with my
configuration, is it a bug or MDS and DS just shouldn't be run on one
machine?
Best regards,
Jiri Kortus
