Lustre 2.15 Compile Issue

[jdmaloney]

Hello, We're running DDN's ExaScaler 6.x branch which is Lustre 2.14 technically (but with a ton of 2.15 back-ported features since 2.15 is the LTS).

We're seeing the following when compiling RBH 3.1.7 against this version of Lustre.

lustre_tools.c:857: error: "IOC_MDC_GETFILEINFO_V1" redefined [-Werror]

Hi folks,

Just to add an update / data-point, I am having the same issue compiling a "git checkout 3.1.7" using lustre 2.15.2 on CentOS 7.9

Anyone else have successful builds in a similar environment?

@CanWood I was able to get around this by commenting out lines 854-858 in the file src/common/lustre_tools.c doing so allowed me to compile and run things.

I ran into the same issue with 3.1.6 and lustre 2.12 and commented out the same lines (although they're 852-856 in 3.1.6) to build the RPMs. Thanks!
