Hello, I can repeatedly trigger this bug by making the "data" portion fill up. If you remember the partition is 6 TB but in btrfs filesystem df Data is shown as only 2TB when in fact it should be nearly 6TB. So this has nothing to do with kernel bugs. The filesystem on disk is structured incorrectly. How do i fix this? How do I make "Data" bigger? What is it exactly? Thanks P.S. Sorry about reposting twice, apparently Google's "Inbox" app doesn't allow posting plain text at all and the mail got rejected from the list.
