[lustre-discuss] segfault with 2.15.8 client on AlmaLinux 9.7

[Andreas Dilger]

Hi Steve,
I haven't seen this issue before.  Some things to test out:
- does it work if you run the latest lfs/liblustreapi from master?  It may be fixed already.
- does it work if you run non-interactively, like "lfs setstripe -c 2 ."?
- does it work if you run from the parent dir, like "lfs setstripe -c 2 DIR"?
- what does "strace lfs setstripe -c 2 ." show?
- if you run under GDB, can you report the exact spot where it is crashing?

If it can be reproduced with master lfs/liblustreapi please file a Jira ticket with details.

Cheers, Andreas
