<p>Overkill - not really. The calculations show I need at least 16G
(its currently using ~11G). I was using an odroid-n2 with 4G ram
- slowed to a crawl when it hit swap and eventually crashed. I
moved the master to a much more powerful intel server with 32mb
and it has crashed once but I was hammering it (graphs show it ran
out of ram - need to check if the OOM is disabled on that one).
Cheats like moving swap and the mfs directories to a usb3
connected SSD helped (4-5 times faster than an SD card), but
eventually fell short.<br>
</p>
<p>I have 10 disks (~26Tb) spread across 5, soon to be 6 low power
odroids and an intel atom. The problem came when I put two copies
of 20+ years email (millions of smallish files) on it and then
reconfigured the mail server to use one copy. Yes, I know
...self inflicted! But it did work for a few days! :)<br>
</p>
<p>There are some guide calculations on the moosefs website that
match what I am seeing for usage and support why I want at least
32G. There are still some shortcuts I could use (go back to
putting the small files in a qemu virtual disk) but that had its
own issues. I see some emails on the moosefs website about
masters with hundreds of G ram!<br>
