    Strange File Permissions

    Hey,

    We have a client on CentOS with cPanel and their VPS is corrupt by the looks of things. We have tried to remove the following files but it won't allow us to, give an error of: "Operation Not Permitted".

    Code:
    b--sr-s--t 30068 2036409384  539518322   111,  99 Feb  5  1987  autosave.dev.js
    ?--xrwx--x 29545 1668161637 1769236596 1629757501 Jul  24  2001 jquery
    cr-xr-Sr-t 28711 1948532000 1768431660    32,  44  Jul  1  2002 prototype.js

    c--Sr----T 27728 1818312736 1701585011   114, 101  Jun  1  1975 wp-lists.js
    We've been investigating it for the last 24 hours with no avail.

    Any help will be appreciated.

    Something is very bad here. The files that start with "b" or "c" are Unix devices, not regular files. Given that these are supposed to be JavaScript files and that the dates are not correct I'd say that this VPS needs to be reinstalled. Realistically only files in /dev would only have these flags set.

    Please also check e2fsck -f /dev/your-mount point where these files exist, then try, may be it works.

    Confirm in which directory you are viewing these files.

    Also confirm this directory is not attributed. You can use the following command

    lsattr /parentdirectoryname

    for example this files are under /home/user/test, then you should run the above command as " lsattr /home/user "

    Also some files are using the special permission stictybit ( T ), but you can remove those files as root user if the directory is not attributed.

    Before removing those files confirm these are unnecessary.

    The exact location is: /vz/private/127.old/home/scbuzz/public_html/blag/wp-includes/js/

    We have tried to rebuild the VPS, however, it wasn't successful expressing that a device is busy.

    We are planning to run FSCK on the host, but would rather not do that.

    Please better try e2fsck in rescue mode.

    when you delete file use -> rm -rf "filename*.*", might be some hidden space or something will be creating problem. I have faced many times such conditions and problem is resolved as i mentioned in this thread, if something else then need to check server properly.

    We shutdown the server and ran FSCK but it failed saying that a device is in use or busy.

    That is the error we get when trying to delete these files.

    Is there anything that can be done? As it seems these files are impossible to remove.

    Yes, we ran FSCK from recovery mode.

    I'd rather not allow access since it is a working VPS host node.

    If you want output of commands etc, just post them here and I'll do the needful.

    As others said, this is really odd. Files timestamps are from the past and future and those ? marks indicates about file system corruption or some other issue. Do you have there enough disk space? I barely remember myself this issue but somehow this kind of behaviour remainds me nearing HDD crash or hardware failure.

    Finally jquery is about 1.5GB of size etc. Definitely something is badly corrupted. What is inside of those files? like what command "tail -n 150 jquery" produces?

    Something is not right with that anyway, block devices should be under /dev and nearly nothing creates device files outside /dev.

    Also clock skew is possible there with some really nasty bug with VPS or something. Ask from your VPS host do there happened something strange with main host, might help as well.

    When you have found solution for this, let us know.

    he is the provider of the VPS, vps was bought by vpsright.com, but a 1-2 weeks ago when they had the downtime the VPS never came back up i asked and the files you see above are what vpsright told me, 3.8 TB over the limit, but, we never made, or seen the account named "scbuzz" only WHM plugin's installed was a firewall, softaculous. is there like a virus that makes a account named scbuzz, from what vpsright says its in a directory format like wordpress. it began about: 22/08/2009 20:07. (i was busy while writting this so its has no correct grammer)
