Sectors fail. Partitions do not fail. Logical volumes do not fail. If your disk fails you lose *all* partitions on it. If some sectors fail, the file(s) backed by those sectors will be corrupted -- regardless of filesystem type. If the defective sectors back a filesystem's superblock or other infrastructure, you could well lose the filesystem; but most modern filesystems keep redundant copies of their infrastructure, and fsck can sometimes recover. >What is the advantage of using LVM and several small partitions >instead of one in the size of the sum of the others and not using >LVM? LVM provides immense flexibility in creating, deleting and expanding filesystems. Once you get used to using LVM, which is not difficult, you will never go back to partitions. -- Regards, Dave [RLU #314465] ====================================================================== dwn...@ntlworld.com (David W Noon) ======================================================================
