    • Volume 1 - "FAST data"
    • btrfs filesystem, this volume is synced to Backblaze B2 cloud for backups
  • Disk group 2 - HDD
    • 2x 10TB SATA HDD
    • Volume 2 - "SLOW ephemeral data"
    • btrfs filesystem, this volume is not synced anywhere

At home

Upgrade options

I don't need more capacity but I would like more speed. That'd mean 10G networking, and I'd need that in my workstation as well, though it does have a 2.5G NIC onboard which is a decent start. Otherwise I'd have to get a 10G PCIe NIC, and somehow use the M.2 connector on the back side of the motherboard.

  • DS1621+ has room for a 10G NIC addon, Synology branded but normal PCIe
  • DS1522+ takes a mini 10G NIC, which is the perfect answer in my mind (non-standard vendor NIC E10G22-T1-Mini, but convenient

  • DS2422+ is huge and takes PCIe 10G or 25G cards, that's way outta reach though
  • DS1821+ also takes the same PCIe 10G or 25G cards

The 1522 seems like a pretty clear winner on price.

Let's compare the two on the bottom end for features as well: https://www.synology.com/en-au/products/compare/DS1621+/DS1522+

The older model actually doesn't come off too badly in comparison. I really like that the newer one is lighter and uses less power and has more RAM, but I really dislike that it doesn't have an internal PSU.

Tools

If you're SSH'd to the box, you can install/activate extra tools that you'd be used to having as a sysadmin.

sudo synogear install

Despite being called with "install", all this does is drop you into a subshell with access to the tools, kinda like activating a python virtualenv. You'll need to run it any time you want to use them (or you can mess with your $PATH I guess).

root@iowa:~# echo $PATH
/sbin:/bin:/usr/sbin:/usr/bin:/usr/syno/sbin:/usr/syno/bin:/usr/local/sbin:/usr/local/bin

root@iowa:~# synogear install
root@iowa:~# echo $PATH
/var/packages/DiagnosisTool/target/tool/:/sbin:/bin:/usr/sbin:/usr/bin:/usr/syno/sbin:/usr/syno/bin:/usr/local/sbin:/usr/local/bin

rsync over ssh

Maybe I broke it, but rsync doesn't work as expected without some fiddling. I thought it might be due to cruft in my ~/.bashrc but I don't think it's that.

This works though:

rsync -avx --rsync-path=/usr/bin/rsync furinkan@iowa:/volume1/path/to/files/ /somewhere/local/or/whatever/

The error message suggests it can't find or can't execute the rsync binary at the far end, but I can't tell why.

furinkan@suomi:~$ ssh furinkan@iowa 'echo $PATH'
/usr/bin:/bin:/usr/sbin:/sbin

furinkan@suomi:~$ ssh furinkan@iowa 'which rsync'
/usr/bin/rsync
