Disks fail. Sectors fail. Partitions do not fail. Logical volumes do |
10 |
not fail. |

If your disk fails you lose *all* partitions on it. |

|
14 |
If some sectors fail, the file(s) backed by those sectors will be |
15 |
corrupted -- regardless of filesystem type. If the defective sectors |
16 |
back a filesystem's superblock or other infrastructure, you could well |
17 |
lose the filesystem; but most modern filesystems keep redundant copies |
18 |
of their infrastructure, and fsck can sometimes recover. |

LVM provides immense flexibility in creating, deleting and expanding |
25 |
filesystems. Once you get used to using LVM, which is not difficult, |
26 |
you will never go back to partitions. |
