https://community.hpe.com/t5/operating-system-hp-ux/disk-usage-not-showing-correct-values/m-p/3888561#M281105 Hello,<BR />I have two oracle data disks, one has only a 2.5G tempfile, the other has 4 1G+ files. Doing BDF shows the 2.5G file as about 2M, while the other disk is correct. A du -sk also shows the 2.5G file as 2.x M. An ls -l shows the file as 2.5GB. I have attached image o0f the output. What is going on here?

They do not actually take up space untill used (if ever).<BR /><BR />Find earlier discussions google for: +oracle +sparse +temp<BR /><BR />Add +site:itrc.hp.com and you'll find tow relevant prior topics here:<BR /><BR /><A href="http://forums1.itrc.hp.com/service/forums/questionanswer.do?threadId=992825" target="_blank">http://forums1.itrc.hp.com/service/forums/questionanswer.do?threadId=992825</A><BR /><A href="http://forums1.itrc.hp.com/service/forums/questionanswer.do?threadId=957571" target="_blank">http://forums1.itrc.hp.com/service/forums/questionanswer.do?threadId=957571</A><BR /><BR />hth,<BR />Hein.<BR /> Sun, 29 Oct 2006 12:19:37 GMT https://community.hpe.com/t5/operating-system-hp-ux/disk-usage-not-showing-correct-values/m-p/3888562#M281106 Hein van den Heuvel 2006-10-29T12:19:37Z
