Hello, O.K. I have been thinking about this. If in your case what fails is bcache, perhaps it would be interesting to make a suggestion: There is a Python tool (blocks, as it is in the FAQ) which allows to "transform" a filesystem into bcache without losing data. In the same manner, perhaps the author could add the functionality of returning a "bcacheized" filesystem to its original format, without the bcache superblock (and stuff?). With a tool like that (I guess it would be very easy to add this functionality), you could return your /home to a pure ext4 filesystem and then mount, backup, create a new bcache, etc. -- -- Salutacions...Josep -- -- To unsubscribe from this list: send the line "unsubscribe linux-bcache" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
