Hello everybody, I read these forums a lot but it's the first time I write something.
I build my home server with these parts:
- Intel Atom 330 Little Falls 2
- 2GB RAM
- Promise TX4 SATA300 (PCI Card, 4 s-ata II ports)
I am using various hard drives: one old pata maxtor 300GB for system, 2 x shiny new wd 2tb (4k models, partitioned correctly, so this is not the issue), 1 wd 1.5tb, 2 x seagate 1.5tb 7200.11, 1 samsumg 1tb.
All works perfectly with ubuntu server 9.10 (upgraded from 9.04), 32bit.
After many thoughts, after trying lvm (I don't use it anymore as it reduces, in my case, the reliability of the system as I don't want to use any kind of raid) unionfs, aufs, I finally discovered mhddfs.
I set it up with a huge mlimit, so it balances new files to the disk with more free space.
It works like a charm, especially in read mode. In write mode, instead, it limits the performance roughly to 27MB/s (from windows 7 through Samba), when writing to the same disk, excluding mhddfs (a dedicated share) I get about 60MB/s.
I noticed that mhddfs consumes a lot of cpu (over 50%) in 4 threads.
Did anybody try a similar config with a more powerful cpu? Unfortunately, I can't make a test myself at the moment, I wonder if anyone can help
Thanks a lot
