System Memory: Physical RAM: 6134 MB Free Memory : 190 MB LotsFree: 94 MB ARC Size: Current Size: 1890 MB (arcsize) Target Size (Adaptive): 2910 MB (c) Min Size (Hard Limit): 638 MB (zfs_arc_min) Max Size (Hard Limit): 5110 MB (zfs_arc_max) ARC Size Breakdown: Most Recently Used Cache Size: 67% 1959 MB (p) Most Frequently Used Cache Size: 32% 950 MB (c-p) It does some mail server stuff as well. The two added USB sticks grew to about 3.2GB of metadata L2ARC, totally about 6.5M files on the system. /Tomas -- Tomas Ögren, st...@acc.umu.se, http://www.acc.umu.se/~stric/ |- Student at Computing Science, University of Umeå `- Sysadmin at {cs,acc}.umu.se _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
