Hallo, linux-btrfs, for some hours I was happy ... mkfs.btrfs /dev/sde1 mount /dev/sde1 /mnt/btr <copy about 1.5 TByte> btrfs device add /dev/sdd1 <copy about 0.8 TByte> led to # btrfs filesystem show Label: ''MM2'' uuid: 7400b83c-f3dd-477c-bbf4-7429863a7ef9 Total devices 2 FS bytes used 2.25TB devid 1 size 1.81TB used 1.51TB path /dev/sde1 devid 2 size 1.82TB used 760.50GB path /dev/sdd1 Btrfs Btrfs v0.19 # btrfs filesystem df /srv/MM Data: total=2.25TB, used=2.24TB System, DUP: total=8.00MB, used=260.00KB System: total=4.00MB, used=0.00 Metadata, DUP: total=5.00GB, used=3.53GB Metadata: total=8.00MB, used=0.00 # df -t btrfs Filesystem Type 1K-blocks Used Available Use% Mounted on /dev/sde1 btrfs 3898172184 2416726548 1478325628 63% /srv/MM # fdisk -l /dev/sde1 1 242600 1948684468+ 83 Linux /dev/sdd1 1 242700 1949487718+ 83 Linux # -------------------------------------- All seemed to work well. No "no space left ...". Then I shut down the machine and started it again the next day. btrfs filesystem show showed the 2 devices. mount LABEL=MM2 /mnt/btr and the system crashed with blinkenlights. What goes wrong? How can I restore the data? I have a backup, but I prefer reanimating the 2 btrfs partitions. Kernel 2.6.37 Viele Gruesse!
