Harvesting

I've got 600 plots and have stopped generating any more for the moment, so its just harvesting what I have. I ordered some more 16TB drives for the storage server. Currently I have 3 pools of disks in/attached to it:

NAME    SIZE  ALLOC   FREE  CKPOINT  EXPANDSZ   FRAG    CAP  DEDUP    HEALTH  ALTROOT
pool1  72.8T  26.6T  46.1T        -         -     0%    36%  1.00x    ONLINE  -
pool2  29.1T  26.3T  2.82T        -         -     0%    90%  1.00x    ONLINE  -
pool3  29.1T  26.2T  2.96T        -         -     0%    89%  1.00x    ONLINE  -


Pool1 is 5 x 16TB drives in a raidz
Pool2 is 4 x 8TB drives in a raidz (in external disk enclosure)
Pool3 is 4 x 8TB drives in a raidz

I am thinking of making a pool of 10 x 16TB drives in a raidz2 which will give 2 drives of redundancy and approximately 128TB of usable space, now that I have the drive mounting brackets to fit 10 drives into the Meshify2 case. I know you don't need any redundancy and can simply lose a drive and plot some more, but while that is happening you lose the opportunity where you could be earning from your plots.

It gets rather messy inside the case with all the power and SATA cables when there are so many drives. I can see why some people prefer a rack mount JBOD as the cabling is already done and all you have to do is connect it to the computer and fill it with drives. See THIS video where Caleb (aka Coin Breakthrough) talks about this.

When I checked on the storage server this morning I found it was doing a scrub on all 3 pools. It turns out the Debian/Ubuntu packages setup cron tasks to do a trim on the 1st Sunday of every month and a scrub on the 2nd Sunday. I had my own cron tasks for trimming weekly and scrubbing monthly, not knowing it already had them. Pool1 will finish in a few hours with pool3 a couple of hours behind it, but pool2 in the external disk enclosure wants 29 hours to finish. The external enclosure has a USB 3.0 connection (5 Gbit/sec) but has 4 drives trying to share, unlike the internal drives which have their own SATA connection and can all read/write at the same time.
