    Hi admins!
     
    I need your advises regarding a huge file system dedicated for all Oracle files.
     
    The history :
     
    One year ago, an RP7410 was installed in the purpose to use a tiny database (20 Gb) located on a XP1024 bay. Suddenly, Hp increased the size of the database VG to this value 200 Gb.
    But, a few days ago, an architect asked HP to apply a new sizing (1200GB! ) .
    As you know, HP guys were stuck with all limitations given the first time, when they built the VG structures. That means, just 16384 PE for a vg. Indeed, they used the magical tool (vgmodify) to enlarge those criterias, w/o results. The tool did not work.
     
    So, they just created in a lv, a big file system 1000 Gb (type VxFs) , for all .dbf file, redo log , archive logs.. w/ no possibility to extend it, and 200 Gb in an another lv. The total size of the datas is expected to reach only 600 GB.
     
    Questions :
    ============
     - Are there any known problems about using huge file systems ?
      - Is the command fsck still working , in case of inode failure (I know there is an I/O cache somewhere, but if some inodes are corrupted, is it possible to recover the situation ??
      - Is the command fsadm still working ?
     
    - What are the arguments I could use if I would ask them, to rebuild from zero the server in a proper way ?
     
    thanks by advance
     
     
     
     

    Cordialement, Kind regards, Yours sincerely
