Hello, I have a FreeBSD 10.1 system with a raidz2 zfs configuration with 2ssd's for l2arc . It is running '10.1-STABLE FreeBSD 10.1-STABLE #0 r278805' Currently I'm running tests before it can go to production, but I have the following issue. After a while the l2arc devices indicate 16.0E free space and it starts 'consuming' more than it can hold cache - - - - - - gpt/l2arc1 107G 16.0E 0 2 0 92.7K gpt/l2arc2 68.3G 16.0E 0 1 0 60.8K It ran good for a while, where data was removed from cache so it could be filled with newer data. (Free space was always around 200/300Mbytes). I've read about similar issues, which should be fixed in different commits, but I'm running the latest stable 10.1 kernel right now. (One of the last similar issue is: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=197164 ) Another similar issue reported at FreeNAS https://bugs.freenas.org/issues/5347 suggested it would be a hardware issue, but I have 2 servers which experience the same problem. One has a Crucial M500 drive and the other a M550. Both have a 64G partition voor l2arc. What is really going on here? Regards, Frank de Bot
