Re: [linux-lvm] LVM and Truecrypt

Hi Gordon,

Is there any particular Reason, why a mainboard failure should result in massive data loss? But you can be assured, that a disk failure in such a volume will most certainly result in massive dataloss, since the filesystem spans across all disks.
Is there any partuclar reason for using truecrypt?

Hello all,

I am trying to create a 10TB network share (like a NAS share, but with permission levels) on a dedicated GNU+Linux server to be used on a Linux/Windows network.

I must use truecrypt for full drive encryption. I need the disks to be independently mountable (no striping, parity bits or files spanning across physical drives) (this is because I am afraid of massive data loss from a mainboard failure. If you can show me that this fear is unfounded and that I would definitely be able to recover my data after a mainboard failure, then I would not hesitate to use files spanning across drives). Most importantly, the combined space of the disks (10TB) must appear as 10TB on the network, not 10 @ 1TB drives (if I were using 1TB drives, for example). Resonable continuous write speed is also a factor for me. It is essential that this drive space can be "mounted" (i.e., "mount network drive") on a Windows machine. Different folders must be able to have different permissionn levels for different users, similar to the permission levels available in Microsoft shares (write new files/edit files/delete files/make new folders/delete folders/etc.). After someone connects to the file server, he must not be able to access every file, only those specificly shared to him.

Can someone point me to info on using truecrypt with LVM? (I am new to GNU+Linux. File serving on a Windows Active Directory server is... unpredictable.)
