lfsck touch an EA inode

Bug Major Resolved Fixed nasf Alexey Lyashkov Thu, 8 Oct 2015 13:41:29 +0000 Wed, 9 Dec 2015 04:13:32 +0000 Wed, 9 Dec 2015 04:13:32 +0000 Lustre 2.5.0 Lustre 2.8.0 Lustre 2.8.0 0 8 <p>Hi Fan Yong,<br/> Can you have a look at this one?<br/> Thanks.<br/> Joe</p> <p>This isn't in itself harmful, because the LMA xattr on the xattr inode is not visible or accessible by anything, only the data blocks are used by ldiskfs.</p> <p>That said, it is confusing that OI Scrub is adding the LMA to this inode. It should skip inodes with the EXT4_EA_INODE_FL flag set. </p> <p>It may produce a problems with OI. Like unreclaimable entries. simple example<br/> OI Scrub fill LMA and put record to OI, but none operations will remove it record from OI table.<br/> May be other problems when two keys point to same inode number.</p> <p>Fan Yong (fan.yong@intel.com) uploaded a new patch: <a href="http://review.whamcloud.com/17043" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/17043</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-7268" title="lfsck touch an EA inode" class="issue-link" data-issue-key="LU-7268"><del>LU-7268</del></a> scrub: NOT assign LMA for EA inode<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: 1<br/> Commit: 189878cabee229c08a0c1e0caa0860780bafbc98</p> <p>Oleg Drokin (oleg.drokin@intel.com) merged in patch <a href="http://review.whamcloud.com/17043/" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/17043/</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-7268" title="lfsck touch an EA inode" class="issue-link" data-issue-key="LU-7268"><del>LU-7268</del></a> scrub: NOT assign LMA for EA inode<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: <br/> Commit: af46e574eeebe23c5a6146a134fa00ee91931de3</p> <p>The patch has been landed to master.</p> Development Rank 1|hzxpvz: Rank (Obsolete) 9223372036854775807 Severity
