comment Recover data from a BTRFS RAID5
If there is a kernel panic involved in those lockups you should post it along with your question. Otherwise I'd update kernel and/or put all disks in another box just in case it's the hardware... if it still locks up (and silently at that) you should probably talk to the btrfs devs...

comment Is it reliable to assemble md from two machines at the same time
Forget the filesystem layer, the md layer itself is not fine with it. At least not in a standard setup. Maybe it could work for --build (raid without metadata that never syncs), I don't know. Maybe you should ask the devs on linux-raid mailing list for this.

It would mess up badly.

comment Ctrl-S doesn't work in rtorrent when accessed via screen. Can't start torrents
screen's flow toggle C-a C-f might help with these shortcuts. In -flow mode they may be passed on to the program.

comment Backed up over wrong hard drive
It was supposed to imply that if you do not have backups, your data is already lost, even if you don't know it yet. Be it hardware failure or user error, without backups you just can't recover from anything, and if you can not recover your data is good as gone. The storage that never fails and never forgets data has not been invented yet. If your data is important to you, you have to have backups of it, from the very beginning.

comment Backed up over wrong hard drive
dd can be the right choice in some situations - you just better know what you are doing. There is no perfect way to backup files. I use dar myself but consider it far from perfect. It's complicated to use and some parts of it just don't work well (dar_manager doesn't scale).

comment Automating a disk move & extension?
Thinking about this takes longer than doing it the old fashioned way. And you can still go to sleep while the copy process is running, no automation required. Not that it should take long with SSD, ancient or no...

comment Help with lost software RAID5 on CentOS 6.5
A missing mdadm.conf is never a problem. You seem to suffer from missing metadata (no arrays found). You seem to be having partition tables on partitions, that's all the --examine output is showing. Check if there is any metadata to be found on them (going via one of losetup --partscan, partx, kpartx if you must). Make sure to do all of this in read only mode.

Also check for a full tmpfs, depending how you check it may count as cache/buffer even though it can't be freed short of swapping it.

comment Sorting data faster approach
Try shuf instead of sort -R, it's considerably faster. Of course, doing it in memory (see Perl answer) will beat anything that requires re-reading the entire file in the shell.
