Good morning, Nick- One does not mount the OST block device on multiple hosts simultaneously: the OST is mounted on a single OSS, and the clients connect to the OSS to request I/O (i.e. Lustre is a distributed filesystem, not a shared-disk filesystem).
To make those requests using RDMA instead of TCP, you need to assign an IP address to your RDMA interfaces (e.g. IPoIB ib0) and configure LNet nids x.x.x.x@o2ib. Use o2ib nids in your mount specification, and Lustre will use RDMA (the IP address is just for setup, as I understand it). -Laura ________________________________________ Od: lustre-discuss <[email protected]> v imenu Nick dan via lustre-discuss <[email protected]> Poslano: četrtek, 05. januar 2023 06:12 Za: [email protected]; [email protected]; [email protected] Zadeva: [lustre-discuss] Regarding Lustre with RDMA Hi We have configured the Lustre filesystem and mounted the same on the client. This is being done using IP as highlighted below [image.png] Part 2: Now for the next part, we don't want to use this command: (mount -t lustre 11.11.1.211@tcp:/lustre /mnt/lustre) as the connection is through IP. We want to mount a particular block device as a lustre file system. For example, in the image below we have created 2 partitions on the server of 10G each and we are sharing ost partition to the client as a block device. [image.png] when we are sharing the block device. This is our client and we have got 10G of /mnt/ost. [image.png] After mounting using mount /dev/nvme0n1 /mnt/lustre/ The filesystem type is ext4 and not lustre as mentioned below. [image.png] We want to mount using the lustre filesystem and not ext4. Is there a need to change the lnet configuration? What else is need to be done? _______________________________________________ lustre-discuss mailing list [email protected] http://lists.lustre.org/listinfo.cgi/lustre-discuss-lustre.org
