Does Ubuntu take advantage of multiple swap partitions on separate physical media, from a load sharing point of view? i.e. if one drive with a swap partition is burdened with i/o, will it utilise (other) swap space that resides on a different physical hard drive?
Building a headless home server (command-line only responses, please!). I usually put the o/s, the virtual/swap space and apps+data each on separate drives. While I think I've got directories and mount points clear (even managed to automount an NFS folder from a NAS), swap still seems a little hazy to me...
The Ubuntu install sequence partitioned my main drive with LVM [still unsure if LVM was the best choice for a headless server; but this is not a question, just an observation]
I've got two additional drives I'd like to use. While I see guides for GParted, detail regarding fdisk doesn't seem as thorough.
I realise there's also the "swappiness" setting, but I'm more curious about the possible benefits if Ubuntu is sufficiently "device-aware" to take into account an i/o burdened device vs. an idle one, should it have multiple swap areas at its disposal.
