search for: vnlru

For FreeBSD 4.7 I've discovered the cause of the deadlock, but I can't figure out how to fix it. See below for traces. If the vnode limit has been reached, the vnlru process is kicked and the requestor goes to sleep to wait for the vnlru process to signal that vnodes are available (10% of the vnodes need to be freed). Under our test, none of the nodes meet the criteria for freeing, so the vnlru process goes to sleep for 3 seconds without signaling anythin...

I woke up to a frozen box this morning - it froze up a few more times before I got a handle on it. Basically, the box runs idle but refuses to do disk IO, or does it -very- slowly. Top shows processes stuck in 'ffsvget', 'inode', and 'vlruwk' state. I can get the box responsive again by setting sysctl kern.maxvnods=100000. It starts up with kern.maxnodes=36079. I

Hi, I have a server (Dell PowerEdge SC1435, ServerWorks HT1000) on which I'd like to try installing FreeBSD. I've already failed to make 7.0 work on this box and was wondering if you have information about the behavior of the upcoming 7.1 on this hardware. I've been following the "HT1000 chipset errata saga" thread, and the commits by sos@ to CVS (around Jan 2008), but have
