Hello, I'm trying to debug some problems I've been having with FreeBSD's fsx utility on our test PVFS2 cluster. I ask because I'm trying to track down some file corruption issues with PVFS and Samba--and the Samba people suggested that I try running fs tests like fsx.
We're running PVFS2 1.3.2. I'm using the version of fsx that I've pulled from <http://www.freebsd.org/cgi/cvsweb.cgi/src/tools/regression/fsx/>. Looking at the test code PVFS2's CVS , it looks like the way that I should call fsx is: ./fsx -N 1000 -W -R ${PVFS2_MOUNTPOINT}/fsx_testfile However, this fails with the error: no extend on truncate! not posix! Calling it in "Lite" mode with -L seems to do the trick: $ ./fsx -L -N 1000 -W -R /RAIDS/RAID_2/pvfs-fsx-test mapped writes DISABLED All operations completed A-OK! Then, my question is, should the test succeed in non-Lite mode? I realize that PVFS2 is not a POSIX file system, but it seems that PVFS is failing on truncation tests. However, this might be something that's causing Samba to fail. 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. --Justin _______________________________________________ PVFS2-users mailing list [email protected] http://www.beowulf-underground.org/mailman/listinfo/pvfs2-users
