Invalid file type and changed permission

[ajay_chauhan]

Dear All..

Our Linux server (RHEL 3) was shutdown abruptly few times due to power problem.
After starting the server, we are not able to start our database. During diagnosis, we find that some files ‘s file permission and file type are invalid as shown below.

?r-s--xrwt 1793 2153153527 1460273585 4178288835 Sep 4 18:31 detailbig01.dbf
?-wxr-x--x 1 oracle oinstall 3078430280 May 29 1987 detailbig02.dbf
?-wx----wt 17224 806844749 934746012 4100383846 Apr 21 1991 detailbig03.dbf

We had tried to copy, move, chown and chmod the files using diff user and root also.
But it gives the Error “chown: changing ownership of `summsmall02.dbf': Operation not permitted"

We are afraid of using fsck bcoz it may corrupt our data files ?????
Waiting for ur help.

Ajay.

Hi,

You better copy /usr from other machine and then try to change permission.I think you all reday ran fsck command on that file system manually.
