comment How to close all proceses without restarting a machine?
Runlevel 2 is multi-user and includes the gui... all higher runlevels are the same, at least on debian based distros. I believe on some other distros, 2 does not include the gui, but 3-5 are still all the same.

That does not kill processes; it simply removes them from the shell's job management so they continue to run in the background and will not be killed if you exit the shell.

comment Problems with partition table on 3tb NTFS drive
@ID-ZERO, looks like SystemRescueCD is broken then or you're using a very outdated version. Use the Ubuntu livecd.

comment How to recover ext2 if all superblocks are gone?
sounds like the disk capped out. Check the SMART health of the drive and/or dmesg for more detailed errors.

comment Recover VG after Adding Disks and Rebooting
You shouldn't need to restore anything for lvm... what has gone wrong is that you created the vg with a partition on the disk, and that partition is no longer there. Hopefully the lvm is all still there and you just need to bring back the missing partition.

comment Recover VG after Adding Disks and Rebooting
Partitions don't just disappear on their own.. you might try recreating the partition with fdisk and see if its contents are still intact ( the pv will show up in pvs and the lv should automatically activate ). Also if you just created one lv using the whole ( and only ) disk in the vg, it begs the question why did you use lvm in the first place?

comment mdadm refuses to add second identical disk to array
The new disk may have come with a stupid host protected area enabled which is why it is reporting a smaller size. Check with sudo hdparm -N /dev/sdc

comment What is actually the speed reported by dd?
/dev/md0 is a raid array, not your usb drive.

comment Where are filenames stored on a filesystem?
@StéphaneChazelas, the symlink itself simply contains another name that should be opened instead. The name lookup starts again on the new name, which ( if it exists at all ) is a directory entry somewhere.

@StephenKitt, yea, that question really doesn't have anything to do with this one.

comment Linux doesn't drop FS Caches. Instead Memory starts Swapping
Actually it is not a percentage at all; it is a weight that is compared to the weight of the page cache ( vfs_cache_pressure ) to determine whether to swap or reclaim cache whenever some memory is needed ( whether for an application or for caching newer file data ).
