[lustre-discuss] setdirstripe

[Michael Di Domenico]

now that you mention it, i do think i recall someone telling me that
at some point.  what threw me was the phrasing of the error message.
had it been "this is disabled" i would have remembered

thanks

If so, please know that Neo 3.2 does not support DNE2 striped directories due to numerous possible data corruptions with the underlying 2.11.0 base.  We’ve disabled the capability to protect our customer’s data and file system integrity.  Most of those issues are now fixed in master and b2_12 and HPE supports DNE2 in our 4.x Neo line.  An upcoming release of Neo for your HW will bring the capability to your platform.  Please contact your HPE rep if you need further assistance planning the upgrade and/or if you want to experiment with DNE2 on a test platform prior to an upgrade.
