No RAID here, just LVM - not too different from the default redhat-style
setup of the system drives (except the additional SAN stuff and DB).
Anyway, if the drives are the cause, then riddle me this:
scp test.tar.gz bad-server:/dev/null
Fast to the healthy siblings, slow to the sick machine.
Could the network be the problem? I doubt it. Each system has 4 physical
Ethernet ports, bonded two by two. Each bonded pair is connected to a
different VLAN. This system is slow on both VLANs.
In any case, the explanation would have to account for the fact that
network transfers, *and* local disk activity, are both slow.
