So in ext4 inside a directory if you create lots and lots of files and delete them all, the directory size would increase at the time of creation but won't decrease after deletion. I don't have any system with ext4 at the moment to test it now. This is something we faced 5-6 years back but not sure if it is fixed in ext4 in the latest releases.<br></div><div><div class="m_-864130623090266048h5"><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div></div><div class="gmail_extra"><div><div class="m_-864130623090266048m_5691273583136462071h5"><br><div class="gmail_quote">On Thu, Apr 13, 2017 at 9:26 AM, Pranith Kumar Karampuri <span><<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>Yes<br></div><div class="gmail_extra"><div><div class="m_-864130623090266048m_5691273583136462071m_9176244938813743776h5"><br><div class="gmail_quote">On Thu, Apr 13, 2017 at 8:21 AM, ABHISHEK PALIWAL <span><<a href="mailto:abhishpaliwal@gmail.com" target="_blank">abhishpaliwal@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><p>Means the fs where this brick has been created?</p><div class="m_-864130623090266048m_5691273583136462071m_9176244938813743776m_-5672094628813993784HOEnZb"><div class="m_-864130623090266048m_5691273583136462071m_9176244938813743776m_-5672094628813993784h5">
