Re: [HPDD-discuss] LU-4619 filefrag and FIEMAP

What a I missing here? I download the e2fsprogs source from git.whamcloud.com, ./configure make clean all The resulting filefrag gets Operation not supported errno. I do an strace on using both /usr/bin/filefrag and my filefrag. The strace output is virturally identical up to the point of the FIEMAP ioctl call. The only differences appear to be memory addresses. Even if I copy /usr/sbin/filefrag to my ~/bin/filefrag ( to elminate executable ownership concerns ) I get the same result. Attached are the 2 strace files and a diff of the 2 files. binfilefrag.strace output from using /usr/sbin/filefrag that I copied to my ~/bin/filefrag myff.strace output from using the filefrag that I built from the downloaded source. ff.diff output from the diff the above 2. This was all done on the "swan" nodes at Cray. John On 3/8/2014 11:59 AM, Dilger, Andreas wrote: -- John Bauer I/O Doctors LLC 507-766-0378 bauerj(a)iodoctors.com
