Hi Jesse, Are you by chance using kernel 3.10.0-... from EL7 ? The EL kernels include backports from newer upstream kernels, and if I look at kernel-3.10.0-1160.102.1.el7 for example, I see commits in there at least up to date with upstream 4.17. So that might explain your observation! Cheers, Dan On Tue, Jan 14, 2025 at 4:24 PM Jesse Galley <jesse.galley@hostpapa.com> wrote:
Hello!
The documentation on kernel client features states: "The feature has been supported since the Luminous release. It is recommended to use Linux kernel clients >= 4.14 when there are multiple active MDS."
My question is: what is the actual impact of using an old (3.10) client with a multi-mds FS?
I used a 3.10 client to do some reads and writes of metadata pinned to different MDSs, and it all ostensibly worked fine.
Is it purely a performance problem? Or is there a more serious issue lurking that my simple tests would not reveal.
Thanks!
