Hi! I created filesystem with two devices, 200gb partition each, raid1 both for data and metadata, and 16k leaf and node size. After using it for day or two I got checksum error on one file. scrub reported about 70 more similar errors. Each error was mirrored on two drives, so btrfsck and scrub showed everything as uncorrectable, attempts to make a copy of damaged file just repeated checksum error messages. I had to find and delete each file and then replace it by backup copy. I''m trying to figure out what to do next to find source of a problem. Can anyone help?
