NCLNODE:                528,      0,       0,       0,       0,   0,   0 space_seg_cache:         64,      0,  289198,  299554,25932081,25932081,   0 zio_cache:              944,      0,   37512,   50124,1638254119,1638254119,   0 zio_link_cache:          48,      0,   50955,   38104,1306418638,1306418638,   0 sa_cache:                80,      0,   63694,      56,  198643,198643,   0 dnode_t:                864,      0,  128813,       3,  184863,184863,   0 dmu_buf_impl_t:         224,      0, 1610024,  314631,157119686,157119686,   0 arc_buf_hdr_t:          216,      0,82949975,   56107,156352659,156352659,   0 arc_buf_t:               72,      0, 1586866,  314374,158076670,158076670,   0 zil_lwb_cache:          192,      0,    6354,    7526, 2486242,2486242,   0 zfs_znode_cache:        368,      0,   63694,      16,  198643,198643,   0 ..... skipped ...... Can anybody explain this strange failures in zfs related parameters in vmstat, can we do something with this and is this really bad signal? Thanks! Received on Fri Oct 11 2013 - 18:10:49 UTC
