Hi,
i try to create a server vol file which exports 4 local disks via
distribute translator.
all examples i find use the distribute translator on the client side.
the thing is, i want to be sure that the client doesnt use the disks in
a wrong way
like misconfiguring a primary disk as a replicate or such.
so my primary goal is to export 4 disks as just one brick and all files
are distributed (not striped)
over those disks.
later i will add more disks, but i dont want the client vol file to be
changed!
using the following vol files i get an error:
root at hostname:# ls /media/storage/Media
ls: cannot access /media/storage/Media: Input/output error
the vol's are started like this
server:
/usr/local/sbin/glusterfs --log-level=DEBUG --disable-direct-io-mode -l
/media/74fd89bf-b8c7-4f3d-9092-826613fe1e85/glusterfsd/glusterfs.server.log
-f /media/74fd89bf-b8c7-4f3d-9092-826613fe1e85/glusterfsd/server.vol 2>&1
client:
mount -t glusterfs
/media/74fd89bf-b8c7-4f3d-9092-826613fe1e85/glusterfsd/client.vol -o
log-file=/media/74fd89bf-b8c7-4f3d-9092-826613fe1e85/glusterfsd/glusterfs.client.log,volfile-name=Media,log-level=DEBUG
/media/storage/Media
the server doesnt log anything after the startup
and the client logs from the 'ls' are
[2010-03-14 17:04:04] D [client-protocol.c:4908:client_lookup_cbk]
serverMedia: LOOKUP 0/ (/): inode number changed from
{5445936622006697985,1} to {0,1}
[2010-03-14 17:04:04] W [fuse-bridge.c:722:fuse_attr_cbk]
glusterfs-fuse: 2: LOOKUP() / => -1 (Success)
any idea how i can export the server data with only one sub-volumename,
distributing files over the disks
and having the possibility to expand the storage by adding new disks,
maybe including replication, in the next
months?
thx ll and
kind regards
