I’m about to double the RAM in my ZFS system. It will go from 4GB to 8GB.
Right now, I have:
real memory = 4294967296 (4096 MB) avail memory = 4100382720 (3910 MB)
I’m not interested in any big extensive benchmarks. I just want something simple. Hence:
$ cd /storage/bonnie/
[dan@kraken:/storage/bonnie] $ ls -l
total 0
[dan@kraken:/storage/bonnie] $ bonnie++

After installing the new HDD and the 4GB of RAM:
real memory = 8589934592 (8192 MB) avail memory = 8252592128 (7870 MB)
I also noticed this:
GEOM: mirror/gm0s1: geometry does not match label (16h,63s != 255h,63s).
But everything appears find:
$ gmirror status
Name Status Components
mirror/gm0 COMPLETE ada8
ada9
Drives have been renumbered. I used to have ad0..adad8. My gmirror was previously ada7 and ada8.
Here’s the new bonnie++ output:
