A few questions - What linux version/distro are you on and what type of file system, and how much ram do you have
-----Original Message----- From: u2-users-boun...@listserver.u2ug.org [mailto:u2-users-boun...@listserver.u2ug.org] On Behalf Of Perry Taylor Sent: 04 February 2013 15:57 To: U2-Users List Subject: [U2] [UV] Large File Operations Kill Linux Looking for some ideas on how to keep Linux from becoming largely unresponsive when creating large files. What happens is as the new file is being created the I/O buffer cache quickly fills up with dirty buffers. Until the kernel can flush these out to disk there is no avail buffers for I/O operations from other processes. . The most troubling manifestation of this is the transaction logging check point daemon gets *way* behind putting us as risk if we were to have a failure of some kind. I have tried using ionice and renice to slow the file creation down as much as possible. This help a little but is still a big problem. Any ideas how to get CREATE.FILE/RESIZE to play nice on Linux? Thanks.
