<div dir="ltr"><div><div><div>Oh you want applications to do getfattr to find that it is there?<br></div><br></div>I think I understood what you are looking for now. So basically applications will keep doing creation of some files/directories, whenever a video file is created you want the bricks to set an extended attribute on the directory, so that the application can use it. I don't think this doesn't look like the job of index xlator either.<br><br></div>Why do you not want to set the extended attribute from client and want the fs to do it on-behalf of the application? Setting it from client has benefits like even when one brick is down it will automatically heal this extended attribute etc.<br></div><div class="gmail_extra"><br><div class="gmail_quote">On Mon, Jun 5, 2017 at 12:10 PM, Tahereh Fattahi <span dir="ltr"><<a href="mailto:t28.fattahi@gmail.com" target="_blank">t28.fattahi@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">I want in in mount directory in client side</div><div class="HOEnZb"><div class="h5"><div class="gmail_extra"><br><div class="gmail_quote">On Mon, Jun 5, 2017 at 11:07 AM, Pranith Kumar Karampuri <span dir="ltr"><<a href="mailto:pkarampu@redhat.com" target="_blank">pkarampu@redhat.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><br><div class="gmail_extra"><br><div class="gmail_quote"><span>On Mon, Jun 5, 2017 at 11:24 AM, Tahereh Fattahi <span dir="ltr"><<a href="mailto:t28.fattahi@gmail.com" target="_blank">t28.fattahi@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Thank you<div>I see that this xlator is loaded in server side. </div><div>How can I access to variable in index xlator in client side?</div><div>is it correct? getfattr trusted.index.myvar </div></div></blockquote><div><br></div></span><div>To which xlator do you want this information?
