Hello,
Am I right concluding that there's something wrong in either how freebsd
works with swap partition, or with how gstat reports its activity ?
Because on the consistently woring mirror the situation when only one
disk member is used and the other is not for both reads and writes just
cannot happen:
last pid: 24590; load averages: 6.54, 8.61,
9.86 up 16+04:11:06 15:22:24
79 processes: 1 running, 78 sleeping
CPU: 0.2% user, 0.0% nice, 15.0% system, 1.8% interrupt, 83.0% idle
Mem: 55M Active, 1092K Inact, 2136K Laundry, 61G Wired, 1111M Free
ARC: 33G Total, 1799M MFU, 26G MRU, 3808M Anon, 408M Header, 1032M Other
26G Compressed, 31G Uncompressed, 1.18:1 Ratio
Swap: 32G Total, 1665M Used, 30G Free, 5% Inuse, 5620K In, 2276K Out
