Specifically, when given an empty regular ldiskfs index, load() returns 1 which is wrong. ZFS indexes do not show this issue.</p> LU-10850

Bug Minor Resolved Fixed John Hammond John Hammond Mon, 26 Mar 2018 16:36:19 +0000 Fri, 1 Jul 2022 09:55:54 +0000 Sun, 6 May 2018 04:27:41 +0000 Lustre 2.12.0 0 3 <p>It's not that they don't iterate correctly. Rather the issue is that when created ldiskfs IAM indexes have a single zeroed-out key and record. This is easy to fix but it needs a small change in fld.</p> <p>John L.
