Hello, Amir I am evaluating ext4-snapshot (on github) for TAOBAO recently. The snapshot of an ext4 fs is READONLY now, but we do need to write data into snapshot. We also want using ext4-snapshot to do online-fsck on Hadoop clusters, but our hadoop clusters are using no-journal ext4 now. So we have some question 1. Will it be possible to implement a writable ext4-snapshot ? 2. Will it be possible to snapshot a no-journal ext4-fs ? 3. What's the difficult point of implementing above ? Any of your reply will be appreciate -- -- Best Regard Robin Dong -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
