e2freefrag say "Inappropriate ioctl for device while calling fsmap"

Bug Minor Open Unresolved WC Triage Shuichi Ihara Mon, 21 Aug 2023 02:03:45 +0000 Tue, 29 Aug 2023 05:27:46 +0000 Lustre 2.16.0 0 4 <p>The summary at the start of e2freefrag is also based on the superblock block counts, (which is not updated while mounted) and not the actual free block counters in the group descriptors. It would be better to use the actual block counts. </p> <p>Andreas, the free block counters are based on the result from the ioctl when doing online scanning,<br/> we only use the free blocks from superblock when doing offline scan, which means device is umounted anyway. So I think it's fine here.<br/> We are seeing the ioctl error is because we don't pass through the ioctl to ldiskfs on server, I got a patch for this.</p> <p>"Li Dongyang &lt;dongyangli@ddn.com&gt;" uploaded a new patch: <a href="https://review.whamcloud.com/c/fs/lustre-release/+/52147" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/c/fs/lustre-release/+/52147</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-17042" title="e2freefrag say &quot;Inappropriate ioctl for device while calling fsmap&quot;" class="issue-link" data-issue-key="LU-17042">LU-17042</a> target: allow fsmap ioctl<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: 1<br/> Commit: 9cc7567fc163369a060c3f14be944042c1f4d676</p> Related Development Epic e2fsprogs Rank 1|i03ten: Rank (Obsolete) 9223372036854775807 Severity
