Description Igor Valkov 2021-03-20 12:56:14 UTC
FreeBSD 13.0-RC2. 

ARC-cache uncompressed size if more than 2TB looks like this: 

96 processes:  1 running, 95 sleeping
CPU:  0,1% user,  0,0% nice,  0,1% system,  0,0% interrupt, 99,8% idle
Mem: 1686M Active, 3160M Inact, 168K Laundry, 238G Wired, 247G Free
ARC: 214G Total, 133G MFU, 80G MRU, 4600K Anon, 646M Header, 880M Other
     206G Compressed, K Uncompressed, -8,05:1 Ratio
Swap: 256G Total, 256G Free

Uncompressed size is not showed and compress ratio becomes negative.
