comment directory structure vs file system
The "magic inode" number is specific to the ext2 series of filesystems. It does not apply to most ( all? ) others, such as xfs or btrfs.

comment Why are these files in an ext4 volume fragmented?
Each extent has a maximum of 32k blocks because that is the maximum length an extent descriptor can cover. Extents are not fragments. If you notice several of the extents' physical blocks immediately follow those of the previous extent, and so do not constitute a fragment ( 6 extents vs 3 fragments ).

comment Providing /bin and /lib inside a chroot jail
The intent of the question seems to be to provide access to the existing files rather than copying them into the chroot.

comment How do I use new fdisk table without reboot (kpartx)?
More recent versions of parted / partprobe will not give such an error and can be used on a mounted partition without reboot.

comment Why . /home/Desktop is incorrect and ./Desktop is correct?
More precisely, any path that does not start with a / is relative to the current directory. Every directory has a file named . that refers to itself, hence, ./Desktop means the the Desktop subdirectory in the current directory. Of course, you can just drop the ./ part and it means the same thing with less typing.

comment How do backups that use LVM work?
@romascom, what? Yes, lvm has to keep track of what blocks have been relocated and what have not. This has nothing to do with the backup though.

comment How do backups that use LVM work?
The point of the snapshot is that you do not need to stop the database or whatever else is writing to the disk at the time. Backing up the files without snapshots requires this so that you don't have the file changing after you already backed up part of it. With the snapshot, you get a consistent image that when you restore, is no different to the database than if you had suddenly lost power at the moment of the snapshot ( and they already cope with that ).

comment Where does network waiting go in 'top'?
Question makes no sense... waiting for network IO does not use any cpu time.

comment error when install library ubuntu 10.10
10.10 has been end of life and unsupported for years. You need to use a supported release or your system will quickly be hacked using unpatched vulnerabilities.

comment kexec doesn't unmount root filesystem
Looks like a bug in systemd ( or rather its units/scripts ) which you should report to debian. It should be remounting the filesystem read-only as the last thing that happens before the call to kexec, which would prevent this from happening.

comment Can't figure out what all these sd drives are
Instead of pictures, copying and pasting the text would be better, but yes, it seems that vmplayer is emulating a whole ton of virtual disk drives that are each only one sector long, which seems to be a rather silly thing to do.
