Bill, JFS journalling doesn't journal data changes, only changes to metadata. So in a filesystem with lots of file and directory creates and deletes its useful. In the TSM situation, such changes are rare, and so JFS doesn't buy you a lot in terms of recoverability.
Steve Steve Harris AIX and TSM Admin Queensland Health, Brisbane Australia >>> [EMAIL PROTECTED] 23/01/2004 0:38:54 >>> The "new" TSM runing guide recommends using RAW volumes for performance reasons. I have a client that doesn't want to go RAW because the JFS logging goes away. I'm not that AIX savy to be able to argue one way or the other with him... Going RAW for performance, does that take away from recoverability in the case of system crashes or filesystem problems?
