Hi,
I had the following doubts about the functioning of lustre.
1. Whenever a file creation request is sent from the client, the request is
sent to MDS from where a list of OSTs, file metadata etc is received.
After this point does the data flow through the OSS to the OST or does
the
ly the key here. I'd look at the arguments to the

Hi,
Below are the steps I executed in configuring MDS.
1. mkfs.lustre --fsname lustre --mdt --mgs /dev/vg00/mdt
2. mkdir /mdt
3. mount -t lustre /dev/vg00/mdt /mdt
I see the below error after step 3:
mount.lustre: mount /dev/mapper/vg00-mdt1 at /mdt failed: No such device
Are the lustre
