Hi,
I created an OST today by running:
mkfs.lustre --fsname=testfs --ost --mgsnode=192.168.6.199 at tcp /dev/sda3
(ltcl list_nids in the mdt/mgs gave me the 192.168.6.199 at tcp hint)
When I want to mount it, I get:
mount -t lustre /dev/sda3 /mnt/test/ost0/mount.lustre: mount /dev/sda3
at /mnt/test/ost0 failed: Input/output error
Is the MGS running?
So I wonder: is there anything else I should tell the MGS to do besides
mounting it? (It *is* mounted and running)
Also: I want to create another OST in the same server as the previous
one. How can i distinguish each (besides knowing which device they're
using). Is the --fsname option to be used for that purpose? I first
understood the fsname should be the same for all the mdt/ost but now I
think it again maybe it should be different for everyone?
Your help on that will be highly appreciated :)
Thanks,
