Does ocfs2 support spare files? Specifically: dd if=/dev/zero of=el5dbtest3.db.img bs=1024 seek=35000000 count=0 on a ext3 filesystem takes almost no time at all to run, and is clearly sparse. The same command on a ocfs2 mount takes minutes, and df reports the space as used. (I'm using this with OVM Server 2.1.1) --- I just googled the question, and it seems that it *should* support the spare file, as the patches were submitted over a year ago. ------------------ Matthew Barr Community Connect - Senior System Engineer e:mbarr at communityconnect.com c:347.682.8380 aim: matthewbarr1
