Could you get the log on MDS?</p> <p>Hi Shuichi, I tested chgrp on a directory with 1M files, and it succeeded.</p> <p>What's the average file size on your setup? And the stripe count? After the client stalls, can you get the console messages? </p> <p>I will test with more files up to 4-5M.</p> <p>Hi Ihara,</p> <p>Do you have more informations on this now? And if possible could you try chmod recursively on a directory? chgrp will send SETATTR RPC to OSS, while chmod won't, this could help narrow down the cause of this hang.</p> <p>Thanks,</p> <ul class="alternate" type="square"> <li>Lai</li> </ul> <p>We have been unable to reproduce, and the customer has since upgraded, so this can be closed</p> Development Rank 1|hzw2bj: Rank (Obsolete) 10458 Severity
