Hello. Patch worked as expected - no compresion on l2, but a) l2arc couse big overhad on fs io b) after some time errors apears again. For now best choice not to use any patch on system so, for now we delete next changes from system 1) http://svnweb.freebsd.org/base?view=revision&sortby=file&revision=256889 2) http://svnweb.freebsd.org/base?view=revision&revision=255753 Yes, zpool status says cache gpt/cache0 ONLINE 0 0 0 block size: 512B configured, 4096B native gpt/cache1 ONLINE 0 0 0 block size: 512B configured, 4096B native gpt/cache2 ONLINE 0 0 0 block size: 512B configured, 4096B native But l2arc work as expected (no errors, no noticeable performance problem ) There is many another problem with performance on freebsd 10 after implement new vmem subsystem (at least no problem was before) but thay not corespond to l2 Don't even know what to do with situation.
