Hi All,
Has anyone seen these failures when running xfstests on ext4?
My test and scratch partitions are dedicated for xfstests.
Thanks,
Amir.

I've not seen it, can you investigate with lsof etc? They both work for me on a quick test, anyway, on a .38 kernel. What are you using for your partitions under test? -Eric > Thanks, > Amir. _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs ^ permalink raw reply [flat|nested] 5+ messages in thread

OK. I have not given complete information. It does not fail indefinably. I can umount the fs immediately after the failure. Only the test fails because fsck sees a mounted fs. There must be a bit of a delay in the umount that causes the problem. > > They both work for me on a quick test, anyway, on a .38 > kernel. Problem existed for me in .37 as well. I don't think it is kernel (or fs) related. I think it is a system problem, but I fall short of ideas how to fix it. > > What are you using for your partitions under test? > Currently, I have /dev/sda5,6,7,8. I used to work with LVM, but lstat64 didn't like the /dev/mapper links, so I switched to raw partitions. Although I was puzzled that xfstests could not work over LVM partitions It could when I changed lstat64 to stat64, but then I changed it back thinking it was causing my problems. > -Eric > >> Thanks, >> Amir. > > _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs ^ permalink raw reply [flat|nested] 5+ messages in thread

I tried to fix lvm, once, but all the dev symlinks vs. mtab vs. /proc/mounts was a rat's nest, and I gave up... :) -Eric >> -Eric >> >>> Thanks, >>> Amir. >> >> _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs ^ permalink raw reply [flat|nested] 5+ messages in thread

USE_REMOUNT=1 fixes (bypasses) the problem for non scratch tests, so I'm good with it for now :-) Amir. _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs ^ permalink raw reply [flat|nested] 5+ messages in thread
