It seems around the switch to OpenZFS I would have arc clean task running100% on a core. I use nullfs on my laptop to map my shared ZFS /data partiton into a few vnet instances. Over night or so I would get into this issue. I found that I had a bunch of vnodes being held by otherlayers. My solution was to reduce kern.maxvnodes and vfs.zfs.arc.max sothe ARC cache stayed reasonable without killing other applications.That is why a while back I added the vnode count to mount -v so that I could see the usage of vnodes for each mount point. I made a script to report on things:
Do you see this also with the nullfs mount option "nocache"? Bye, Alexander. -- http://www.Leidinger.net [email protected]: PGP 0x8F31830F9F2772BF http://www.FreeBSD.org [email protected] : PGP 0x8F31830F9F2772BF
