I would probably tune lotsfree down as well. At 72G of ram currently it's probably reserving around 1.1GB of ram. http://docs.sun.com/app/docs/doc/819-2724/6n50b07bk?a=view Ethan -Original Message- From: zfs-discuss-boun...@opensolaris.org [mailto:zfs-discuss-boun...@opensolaris.org]

http://opensolaris.org/jive/thread.jspa?threadID=105702tstart=0 Yes, this does sound very similar. It looks to me like data from read files is clogging the ARC so that there is no more room for more writes when ZFS periodically goes to commit unwritten data. I'm wondering if changing

2009-06-17 Thread Ethan Erchinger
Hi all, Since we've started running 2009.06 on a few servers we seem to be hitting a problem with l2arc that causes it to stop receiving evicted arc pages. Has anyone else seen this kind of problem? The filesystem contains about 130G of compressed (lzjb) data, and looks like: $ zpool status -v

This is a mysql database server, so if you are wondering about the smallish arc size, it's being artificially limited by set zfs:zfs_arc_max = 0x8000 in /etc/system, so that the majority of ram can be allocated to InnoDb. I was told offline that it's likely because my arc size has been
