*IF* you have not rebooted and at least one partiton on your /dev/sda is in use (as it seems), then /proc/partitions still contains the correct data (the kernel does not re-read the partition table of a disk which is in use), so for example mke2fs /dev/sda1 sould build a filesystem with the correct start and end points (even if the partition table on disk is corrupted). With a correct filesystem on disk then existing tools should help: perhaps testdisk is not useful (it searches sane files in sane filesystems when the partition table is corrupted), but there are also tools like gpart that should work to reconstruct a corrupted partition table when the filesystems are sane. If you have lost *only* /boot then it sufficies to umount /boot, recreate the partition table, recreate the filesystem for /boot/, remount /boot , reinstall the kernel and the boot loader. If you have also lost the beginning of the filesystem in the encripted lvm partition then the recover is much harder and I have no idea. But if you are still using the / filesystem without errors then it is quite possibly still sane. -- Chi usa software non libero avvelena anche te. Digli di smettere.
