[Lustre-discuss] mount.lustre: mount /dev/sdd1 at /hpcdata/ost1 failed: Protocol error

[Christian Gajan]

Hi,

my lustre configuration is RHEL5.1 (2.6.18-53.1.13 + lustre patch) + 
OFED 1.2.5.5 + lustre 1.6.4.3
my lnet seem to work correctly but when I try to configure my OSS I got 
a Protocol error at the mount step
Here some detail

MDT/MDS server
# modprobe lnet
# lctl network up
# lctl list_nids
192.168.1.17 at o2ib
# mkfs.lustre -fsname hpcdata --mdt --mgs /dev/sdb2
# mkdir -p /hpcdata/mdt
# mount -t lustre /dev/sdb1 /hpcdata/mdt
ALL is ok here

OST server
# modprobe lnet
# lctl network up
# lctl list_nids
192.168.1.16 at o2ib
# lctl ping 192.168.1.17 at o2ib
12345 - 0 at lo
12345 - 192.168.1.17 at o2ib
# mkfs.lustre --fsname hpcdata --ost --mgsnode=192.168.1.17 at o2ib /dev/sdd1
# mkdir -p /hpcdata/ost1
# mount -t lustre /dev/sdd1 /hpcdata/ost1
mount.lustre: mount /dev/sdd1 at /hpcdata/ost1 failed: Protocol error

I've made a mistake ?
is it a bug (a quick search in bugzilla.lustre.org give nothing) ?

Thanks in advance for your help

regards
