Didn't hear back from anyone regarding if there is a way to determine if I am running the ext3fs with htree. Is there a way I can do it without checking the src code since I am running the precompired redhat kernel with 8.0? Perhaps an entry under /proc somewhere?

Andreas was kind enough to point out that not neccesarily all ext3fs have htrees ready to go. I am running redhat8.0 out of the box. How can I check if ext3fs with htrees is running? I can download the kernel source, but I don't know what options were used when it was built by redhat. Thanks much for all of your help. -Parker -----Original Message----- From: Andreas Dilger [mailto:adilger@clusterfs.com] Sent: Tuesday, January 14, 2003 2:12 PM To: Parker Johnson Cc: 'ext3-users@redhat.com'; Ops Subject: Re: ext3fs still uses sequential search of file names in directories?

Not necessarily (depends on kernel/filesystem config). Please search for "htree" and/or enable the indexed directory feature in the 2.5 or patched 2.4 kernel.
