comment tar causes USB disconnects & reconnects
You have some really broken hardware somewhere... I'd check the power supply to that usb port; it may brown out when the sd card load goes up from activity.

comment Why is dd so slow with a bs of 100M
Also you shouldn't be putting wear and tear on the drive and filling all of its erase blocks by writing it all with zeros... if you want to erase the drive, use hdparm --security-erase to direct the drive to wipe itself.

Isn't that slow? Well that depends entirely on how fast this drive is supposed to be, which we have no idea.

comment rsnapshot taking a long time to backup, are the scripts correct?
Umm... your subject line said you are using rsnapshot, but the snippet of script you posted shows nothing of the sort. That smbclient command just downloads everything from that server share using tar as a transport. You really should show the whole script.

comment Extracted files to /usr, system seems broken now
Set the sticky bit and group ownership to staff on /usr/local -- it's just root.root with no sticky.

comment ext4 to btrfs conversion: If I accidentally lose power to the system during the conversion, will I lose the data?
A flying write is a capital crime in the disk world; any disk doing so is defective. The emergency power off head retract is designed to prevent damage to the disk, not cause it.

comment Extracted files to /usr, system seems broken now
That is very strange... ubuntu doesn't do this and I don't see how it could cause a problem. The intent seems to be to allow the group "staff" to install programs to /usr/local directly rather than having to su(do).

ditch the ssd boot drive; it is of no benefit to a media server.

comment Why ext4 File System is better than NTFS?
Nice answer? This isn't an answer at all. At best it is a comment that the original question is flawed.

comment access to USB drive broken after changing uid
Check the permissions of course.... they are probably still configured for your old uid. This is one reason why you should never change an account's uid.

comment Why does BIOS needs to load first stage boot loader from MBR, but this is not the case with UEFI?
Besides one or more boot loaders, the ESP can also contain EFI drivers and applications. Likewise, the firmware could support filesystems other than fat and then you don't need the ESP. I believe some Macs have support for booting directly from hfs. There's an open source EFI firmware implementation out there and while I haven't checked, I'd bet it can boot directly from ext4.

comment Why does BIOS needs to load first stage boot loader from MBR, but this is not the case with UEFI?
@mikeserv, that's not what he said ( or at least not the part I quoted ).. the part I quoted says that the whole partition is the boot loader.. that's not true... it's a filesystem that holds various files, one of which is a bootloader ( and there can be multiple ones installed, which was always a problem with bios ).

comment Why does BIOS needs to load first stage boot loader from MBR, but this is not the case with UEFI?
"UEFI uses an entire partition as its first stage boot loader" is a bit incorrect. It uses a file that just needs to be stored in a partition that it can read, and the only filesystem type it is required to be able to read is FAT.

comment RAIDing with LVM vs MDRAID - pros and cons?
You are in fact, getting that error due to the version of lvm in wheezy being extremely old and buggy; it works just fine for me here on Ubuntu 14.04 with lvm version 2.02.98 ( I believe jessie is at least that new ). Secondly, the command you showed failing is a resize -- reshape is something entirely different. Reshape means changing from raid1 to raid5, or from a 3 disk raid5 to a 4 disk raid5. That is still unsupported, but simply changing the size works fine.

comment RAIDing with LVM vs MDRAID - pros and cons?
LVM has always supported raid1 and raid0. It was more recently that they dropped their own implementation and instead internally use md's raid personality code, opening up the other raid levels.

comment Ethernet only works when PC booted with cable plugged in
Sounds like a busted router then. You might fire up wireshark and see if any packets are being received.

Retry the DHCP request? Try using a static IP address?

comment Boot process - Dev sdX name changes
Odd. It should be hd0, since the bios always makes whichever drive it loaded grub from hd0. Like I said before though, if the drive where /boot is changes to another number, then grub won't be able to find grub.cfg in the first place, so it won't make it to the search command.
