The next SL 4.X i686 kernel will have this option changed (it requires disabling netdump patches). I would suggest to use SL4 for x86_64 for your file servers (providing you have hardware which can support it): 4K stacks are issue only on 32bit architecture. > there's also a "dmapi" rpm in there which I haven't installed, I'm not sure if > I need to or not? Unless you have applications using DMAPI (Data Management API): no.

Yes it will work. BTW: I looked little bit at CentOS XFS kernels hoping that they will have a newer codebase of XFS there .. nope: it seems that they just do the same as we (plus enabling 4K stacks) .. unless that changed recently ..
