[Ocfs-users] OCFS and removing directories

[Matt Daniels]

What about the issues with creating and removing directories?  We'd never seen that until 1.0.9-12, and I see a similar item being discussed on ocfs-devel the last couple of days.

We're hesitant to proceed here, as we're in production, and are even considering downgrading ocfs.  Is it known when the directory issue arose?  We've been running 1.0.9-12 in production for several weeks, and just came upon this when attempting to move our archived logs back from ext3 to ocfs.

Thanks for any insight.

rigth - what you could do is get emc to fix the performance issues :)
when yo urun without you can verify the differences (again, look at
actual database io throughput) and if they re big, they have to handle
it

we ve had a large number of complaints and powerpath is binary only we
can't fix it on our end as we don'tdo anything wrong in our stack
