See http://oss.sgi.com/projects/xfs/101_qa.html for a description of what 
testing is done.

We use a number of open source tests including but not limited to the following:
  connectathon (connectathon.org)
  Linux Test Project (http://sourceforge.net/projects/ltp/)
  lmbench (http://www.bitmover.com/lmbench/get_lmbench.html)
We also use a number of tests that are not currently open source.

>4. Is xfs release 1.0 work with LVM?

Yes, for more information on 1.0 look at the 1.0 release announcement 
at http://oss.sgi.com/projects/xfs/mail_archive/0105/msg00001.html

>5. Do you have Regression Test System(RTS) test suite, I know it from XFS

Some of these tests from RTS are included in the tests from the Linux Test 
mentioned above.

>6. Is there any major problem with xfs release 1.0?

I know of some NFS panics that were fixed in later releases.
