I'll see what "find /mnt -type f -size +1G" finds :) . Now that I think about it, though, it sounds like it could explain the sudd= en surge in total data size: for one very big file, several chunks/extents are created, but the data cannot be copied from the original ext4 extent. So far, the above find command has only found a few handful of files (plus = all the reflinks in the snapshots), much to my surprise. It still has one subvo= lume to go through, though. And just for completeness, that same find command didn't find any files on = /, which I also converted from ext4, and for which a full balance completed successfully. So maybe this is in the right direction, but I'll wait and s= ee what Chris Murphy (or anyone else) might find in my latest dmesg output. --=20 Marc Joliet -- "People who think they know everything really annoy those of us who know we don't" - Bjarne Stroustrup --Sig_/z1ocOCCKnNYv7dxzcvX/f94 Content-Type: application/pgp-signature; name=signature.asc Content-Disposition: attachment; filename=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAEBAgAGBQJTy6rLAAoJEL/Q5oYsiHj0y/IP/3fxSlat3imK+J8kD8imnKrB h1KW75aQagHQKU/+yjYlwwvLA6AqqZttpmNcnnyqjWl77tcRZBK4u7o/1GpIBSnu uYjKkxKZ3omhbyWWSRCQz6fZE2M74HBXk4KTtHOpxZ2Uj3ZSStS0YPcz+61xrGXC G0LZpsc5l/EAhF0o1aVqG73ednGk2DrOoFED0sWfYA0l+Dwka7sMprwG6cy+P94M uNXRJbJWcfanFuK1JwqwIYnm1x9ivrtR64X9xV+G2G/fsh92gQi8ynLLTPPd+9F8 H1VFY2p3nhAFyGeoMhGi4fyQO8hBptAZlRbi1IC5OgnDAQ9pngR8kVcwq6foxas8 sQO8z8vyXU/THb6a43u6DJDPA/NCLEctORibLvP+/07zDm2S5mk0ptoguhgfbqLb uPjPEPPpat9KwU191b1vx2PI27AGy79tOnnGJAb14SH+vnidtl+9CBMEVgrO9Ylq JN7THJwLpWYO5IHtsfjNFuSZFTodxfBQTjMMWOjzySGU1g0oJm7iXC4kGoHsaOSX 4N1WW1SBH9U5PeOil71LX4Ltq6ohzNcqQhS6waCvjW3ejlWRICqs6yAeIWRPqPqC 6AJbOE7pm/PZ2x3jt0Ao6XCEEw0oO/345t+v5cgAVm1o4eA0DhwOpQTXzfWJYTsL RAZkPJWsc+vOnDQCxYW2 =cQVk -----END PGP SIGNATURE----- --Sig_/z1ocOCCKnNYv7dxzcvX/f94--
