Hello, I am working on incorporating failover and high availability functionality with Lustre into one of our new research clusters.
I am also a bit of a lazy sysadmin, and prefer to not have to modify much on a day-to-day basis. I am using the ROCKS cluster framework in conjunction with Lustre, so a good deal of the work is handled in an automated fashion. I have a question, though ... I have redundant MDS/MDT servers, and when generating their /etc/fstab files, I have them both list the MDT volume under their mounted drives (so that they both mount the metadata volume). Being a bit of a neophyte, I¹m not sure if this is the right thing to do. Is this going to cause a problem in future? What are the possible consequences of both hosts mounting the same metadata volume simultaneously? How do the OSTs handle this situation? thanks, Klaus
