I also can say this procedure works fine with a little tweak to the .spec file for building the server packages. It works well also with kernel 3.18.33, the latest one I tested with Lustre/ZFS On 24/06/16 13:15, Christopher J. Morrone wrote: Yes, it is all a lot harder than it should be at

The error indeed does exist. It hapened to me too. For my own Lustre server needs I just fixed it commenting out two lines in the .spec file since I am not running Lustre in High Avilability. On 29/06/16 11:41, Christopher J. Morrone wrote: On 06/29/2016 10:36 AM, Martin Hecht wrote: Hello

Hello, I have just seen that you managed to mount with a different kernel, but let me come back to this error when building your own rpms for a specific kernel. Independent if you use it or not, I believe on lustre servers you need to have heartbeat installed nowadays. This is not installed by de

One caveat - the Linux VFS still serializes file creates/unlinks in a single directory, even though the server allows them in parallel (it doesn't use the VFS). Even lookups within a single directory are serialized on the client by the VFS except with the very latest kernels, and Lustre hasn't
