Our current Lustre servers run the version 1.8.1.1 with the regular ldiskfs.
We are looking to expand our Lustre file system with new servers/storage and upgrade to all the lustre servers to 1.8.4 as well at the same time. We would like to make use of the ldiskfs-ext4 on the new servers to use larger OSTs. I just want to confirm the following facts: 1. Is is possible to run different versions of ldiskfs on different OSSs of the same lustre file system. 2. Can I install the Lustre RPMs meant for the ext4 system on our older servers that were formatted with the older ldiskfs and expect it to work? Do I have to do any ext3-ext4 conversion or equivalent to make this work?
