Evgeny, could you verify <a href="http://review.whamcloud.com/#change,1259" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/#change,1259</a> is included in your lustre code?</p> <p>Yes, we are using this fix as a part of 1.8.7 release. But if it matters, it is deployed on n1 only, on other Lustre nodes we use 1.8.2</p> <p>The difference I see in your scenario output is that we use password-less connection by ssh.</p> <p>I made ssh password-less, and it showed the same result:</p> <div class="preformatted panel" style="border-width: 1px;"><div class="preformattedContent panelContent"> <pre>[root@vivaldi tests]# mount|grep /mnt/lustre vivaldi@tcp:/lustre on /mnt/lustre type lustre (rw,user_xattr,acl,flock) [root@vivaldi tests]# ssh chopin mount|grep /mnt/lustre vivaldi:/mnt/lustre on /mnt/lustre type nfs (rw,nolock,addr=192.168.111.129) [root@vivaldi tests]# cat /tmp/repr.sh cd /mnt/lustre rm -rf test.sh echo "ls -l" &gt;&gt; test.sh chmod +x test.sh echo "ls" &gt;&gt; test.sh ssh chopin '/mnt/lustre/test.sh' [root@vivaldi tests]# sh /tmp/repr.sh total 56 -rw-------. 1 root root 1891 Nov 30 05:35 anaconda-ks.cfg -rw-r--r--. 1 root root 40354 Nov 30 05:35 install.log -rw-r--r--. 1 root root 8168 Nov 30 05:34 install.log.syslog anaconda-ks.cfg install.log install.log.syslog </pre> </div></div> <p>I want to verify one thing: on node 'n1' is /folder_on_lustre a NFS mountpoint or a Lustre mountpoint? In your test did you use any NFS share?</p> <p>Sorry if I confused you. </p> <p>Clarifying our case:</p> <p>1) n1 - is Lustre node of version 1.8.7 containing folder /folder_on_lustre. <br/> 2) besides n1 this folder is also contained on other Lustre nodes of version 1.8.2 (we specifically deployed Lustre 1.8.7 on n1 to see if resolution of <a href="https://jira.whamcloud.com/browse/LU-146" title="executable files on NFS share failed with &quot;Text file busy&quot; when executed" class="issue-link" data-issue-key="LU-146"><del>LU-146</del></a> fixes our problem).<br/> 3) c1 - is the remote client mounting Lustre folder '/folder_on_lustre' from n1 by NFS to the mountpoint with the same name , i.e. '/folder_on_lustre'<br/> 4) when we run repr.sh on c1 (actually from /folder_on_lustre) we get the described behaviour.<br/> 5) this is what we have in /etc/fstab on c1:<br/> n1_ip:/folder_on_lustre /folder_on_lustre nfs rw,hard,intr 0 0</p> <p>Evgeny, I tested the same as you said. I'm afraid you didn't upgrade MDS to Lustre 1.8.7; <a href="https://jira.whamcloud.com/browse/LU-146" title="executable files on NFS share failed with &quot;Text file busy&quot; when executed" class="issue-link" data-issue-key="LU-146"><del>LU-146</del></a> is a fix for MDS, upgrading client only won't help.</p> <p>Lai, </p> <p>I made sure with our IT guys and they confirmed that n1 was not our MDS. We'll test this issue as only we get our MDS upgraded to 1.8.7</p> <p>I think this ticket may be closed. If it reproduces after upgrade I'll reopen it (I think I have the permission to?).</p> <p>Thank you and sorry for bother.</p> <p>No problem.</p> Development Epic export ldlm nfs Rank 1|hzvhpb: Rank (Obsolete) 6517 Severity
