comment Is USB 3.0-to-USB 3.0 data transfer between two Linux OSes possible?
@Gilles, no, as I said usb3 only incorporates the ability for certain controllers to act as either a host or a device, but it is still not a peer to peer protocol: the host drives the clock, and issues the commands, to which the devices are expected to reply.

You will have to be more specific.

Bonding ethernet is quite tricky. It requires special cooperation from the dual NIC driver ( can't bond a different nic ) and the switch, which must support 802.11ad LACP. There is a poor man's bonding driver in the linux kernel, but it can only allow you to send traffic to two different hosts at the same time, not twice the throughput to the same host.

comment Is it good to install Linux on an external hard drive?
"Is xxx good" is not a question because "good" is entirely open ended and subjective.

comment how do I build a bridge between two virtual machines?
@CodeMed, if the netmask on one connection is 255.0.0.0, aka a class A, aka a /8, then it conflicts with 10.*.*.*. Also before I meant that even if the vms are not on their own dedicated network, traffic between them will still not go out on the lan. Other hosts on the lan can talk to both vms, but when the vms talk to each other, it doesn't go over the lan.

@CodeMed, no, it wouldn't. Traffic from one vm to another when they are connected via a virtual bridge in the host doesn't go out on the lan.

I just noticed you are using centos and not a debian based distribution, and I'm pretty sure that /etc/networking/interfaces is a Debian thing.

comment Configuring a mdadm RAID-1 on SSD and HDD
@kasperd, with secure erase, one should know that you are about to erase the whole drive, and in order to use it you first have to set and then specify the password. With the trim-sector-ranges, it isn't obvious that if you get it wrong, you can accidentally screw yourself.

@kasperd, they are dangerous because they destroy data, and so you need to be very careful that you want to destroy data, and that the data you are telling it to destroy is in fact, the data you want destroyed, and not something else.

@kasperd, yes, obviously it needs to not already have been used.. of course, it is easy enough to trim the unused space one time, or wipe the whole drive before you set it up with an hdparm secure erase.

As an alternative to --assume-clean, you can just specify the SSD as the first drive, and it will be copied to the HDD instead of the other way around. You also don't really need TRIM as long as you leave a few gb of the drive unpartitioned so you never write to it.
