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!
