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.
- 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
