[Ocfs2-users] Max number of files?

Hi Joel & Gavin.

Thanks for your replies.

It's ocfs2 created on kernel about 2.6.18 or so, now running on 2.6.29.1.
But ive recently discovered has almost no features enabled. Intend on
remaking it soon.
Could possibly have been quite fragmented, but it has almost 50% free space,
sorry I should have included that.

Does ocfs2 fragment badly with many changes?

I wrote something to find me any big dirs and left it running this
afternoon. Found one with 20000 files but that's about it.
Also discovered that an ftp client regularly opening up a dir of 5000 or so
files, and then adding one, was really putting a slowdown on things. Removed
those files and interacting with the fs directly seem a little more zippy
now.

In the case where things went wrong for me, there were literally no files in
the dir yet.
I had copied only 20 or so before it started erroring.


If only the previous user to experience this problem had returned with more
info.
