1. Once the blank screen happened ot 23:00 UTC instead of 03:00 UTC 2. I tried to disable the caches 3. I tried to rsync via ext3 + btrfs-convert. I noticed something - in old fs the df looked like: Data: total=30.01GB, used=28.42GB System, DUP: total=8.00MB, used=4.00KB System: total=4.00MB, used=0.00 Metadata, DUP: total=1.00GB, used=199.47MB Metadata: total=8.00MB, used=0.00 on new one (with ext3 image): Data: total=33.33GB, used=20.52GB System: total=32.00MB, used=4.00KB Metadata: total=16.64GB, used=11.36GB and without: Data: total=33.33GB, used=20.04GB System: total=32.00MB, used=4.00KB Metadata: total=16.64GB, used=10.88GB Given that lzo compression was used about 4 GB data difference was expected (difference depending on mount options on rsynbc). However: 1. What is DUP? 2. Why metadata is so big on convertion from ext3 while data is small (the sum is about right - 31GB vs 28.5GB)? Regards
