[lustre-discuss] the -14 EFAULT error during pip installations

Sat Feb 7 07:38:03 PST 2026

Anil,

Yes, but this information is also in the manual - I encourage you to take a look.  You can search for "debug" or "debug_mb" to find the relevant commands.

Thanks
Patrick

Hi Patrick,

Is is possible to share how to get debug log.

Thanks & Regards,

Anil,

If you are able to reproduce this, it would be helpful to gather debug logs as described in the Lustre manual (I suggest starting with -1 debug on the client).  As is, this is interesting but not something investigable without more info.

Regards,
Patrick
