According to tutorial I started MGS and MDT on first machine (with IP 
192.168.2.55):
mkfs.lustre --mgs /dev/sdb1
mkdir -p /mnt/mgs
mount -t lustre /dev/sdb1 /mnt/mgs
mkfs.lustre --fsname=testfs --mdt --mgsnode=192.168.2.55 at tcp0 /dev/sdb2
mkdir -p /mnt/test/mdt
mount -t lustre /dev/sdb2 /mnt/test/mdt

On second machine I tried start OST with:
mkfs.lustre --fsname=testfs --ost --mgsnode=192.168.2.55 at tcp0 /dev/sdb
mkdir -p /mnt/test/ost0
mount -t lustre /dev/sdb /mnt/test/ost0

but got this error:
mount.lustre: mount /dev/sdb at /mnt/test/ost0 failed: Input/output error
Is the MGS running?

Machines can comunicate and MGS is probably running.
It is Lustre 1.6.4.2 and kernel 2.6.18
Have you any ideas where could be a problem?
