So, for various reasons, I've ended up with a 45TB Single Linux Logical volume, without a partition table, formatted as NTFS containing 28TB of data (the Filesystem itself is 28TB).

The filesystem was created in Linux, and is mountable by Linux. The problem comes when I try and mount this within a KVM-based Windows VM on the same box. Windows does not see a 28TB filesystem, but a 1.8TB disk containing a few randomly sized unhelpful partitions.

I presume this is because Windows is trying to read the first few bytes of the real NTFS filesystem data as a partition table.

I can see a few possible solutions to this problem, but can't work out how to actually execute any of them:

• Have Windows read an unpartitioned disk (single volume) as a Filesystem?
• Generate a partition table somehow on this Logical Volume without destroying the data that's held within the filesystem itself?
• Somehow fake a partition table, pointing at the LVM volume and export this to the KVM guest (running in libvirt)

The current "partition table" as reported by parted is:

Model: Linux device-mapper (linear) (dm)
Disk /dev/mapper/chandos--dh-data: 48.0TB
Sector size (logical/physical): 512B/512B
Partition Table: loop

Number  Start  End     Size    File system  Flags
 1      0.00B  48.0TB  48.0TB  ntfs

To help support our clients and make our jobs easier, our support team creates and maintains a number of small (often < 50 line) proprietary scripts in a number of different languages to simplify normal tasks. These are currently stored in a number of places, from an internal wiki, to .txt files on people's own hard disks, on internal servers etc. and it's becoming difficult to track down the latest version of each one.

Really, these need to be kept separate and don't really relate to each other enough to be put into a shared source repository, but aren't significant enough to warrant creating a separate RCS repository for each.

Are you aware of any software or practices which would be suitable for managing a large number of these scripts? This would ideally provide the following functions:

• revision control
• web access (download single script over HTTP)
• authentication
• encryption

If there's no standard piece of software or standard practice for this, I guess it'll just come down to creating something simple myself.

This server is a Dell R200 running Ubuntu 8.04LTS using a LSI SAS1068E raid card supplied from Dell, I suspect that there might be some kind of RAID issue with the hardware raid built into the motherboard, but I can't seem to get MegaCLi to return any useful output:

root@81 $ ./MegaCli -AdpAllInfo -aALL

root@81 $ ./MegaCli -PDList -aALL

root@81 $

The disks work and AFAIK the raid software is installed correctly. I've seen this issue on RedHat issues also in the past. The RAID was initially setup through the BIOS on this server and appears to be functioning fine apart from this.

I've setup NIS on Centos 5.3 following the fairly sketchy documentation online, it seems to be working pretty well, however whenever I run ypcat passwd, either from the server or the client, no entries are ever returned.

There's definitely some entries in the /etc/passwd file on the server and I've run ypinit, as well as tried running make in /var/yp to rebuild the database.

ypcat hosts works fine, I get the hosts file from the server, I don't get any errors in the log. Both machines are setup to in nsswitch.conf to read from NIS as well as files.

Any ideas why this wouldn't be working?

So I've got a few servers which I'd like to log centrally but obviously I don't want to pass the data insecurely over the internet.

I've tried syslog-ng but can't make it work in a secure way, a normal ssh -L PORT:localhost:PORT user@host SSH tunnel won't work because I believe that makes the logs appear to come from the local machine, and a VPN seems a bit like overkill.
