So the filesystem is back up but sill need the backport of the patch to 2.7.1 and 2.7.2</p> <p>back port to b2_7_fe.</p> <p>Conflicts were on <br/> ldiskfs/kernel_patches/patches/rhel7/ext4-large-eas.patch</p> <p>Engineering agrees with your assessment and Bob is working on a port</p> <p>If you don't use rhel7, I think you can ignore the rhel7 conflict for now to get you in business faster.</p> <p>Sounds like a good alternative Oleg. I will ignore the rhel7 conflict and move ahead if we get hit with this bug again before a b2_7_fe back port is available.</p> <p><a href="http://review.whamcloud.com/#/c/20820/" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/#/c/20820/</a></p> <p>Thank you Peter.</p> <p>Close this case.</p> Development Rank 1|hzyesv: Rank (Obsolete) 9223372036854775807 Severity
