I have three partitions that receive the same snapshots (and a separate backup for important data). The damaged filesystems do not lose data, but only (!) waste time. The repair attempts have only worsened the problem. I understand the software development problems. I would just like to be able to help you to find the problem. Have a nice day gdb
