Hi justin well it's too bad there is no official upstream fsx source. We use the one from http://www.codemonkey.org.uk/cruft/fsx-linux.c and so far have not seen this 'no extend on truncate' message. > As a side note, the samba people also suggested running one of their > home-grown tests <http://samba.org/ftp/unpacked/junkcode/fstest.c>. > Their test fails with random data corruption. Thanks for the pointer. I'll add it to the nightly tests. ==rob -- Rob Latham Mathematics and Computer Science Division A215 0178 EA2D B059 8CDF Argonne National Labs, IL USA B29D F333 664A 4280 315B _______________________________________________ PVFS2-users mailing list [email protected] http://www.beowulf-underground.org/mailman/listinfo/pvfs2-users
