Hello, I had a 3 disk raid5 system with btrfs installed. Unfortunately one of the disks crashed. Now I cannot mount the system any more, not even with the degraded option. I suspect the failed disk to have a hw failure. I Think part of the problem might be that I configured the system to not only have the data and metadata, but also the system data in raid config. Is there any chance that I might get my data back from the file system? Currently the system does not boot any more. It was a debian testing system with btrfs version 3.17. The kernel was originally 3.16.0-4-amd64, but now I also have 3.19.0-trunk-amd64 installed. When I run btrfs fi show, I get an error message: Check tree block failed, want=<big number>, have=<another big number> read block failed check_tree_block Couldn' t read chunk root warning, device 2 is missing Sorry, I cannot copy/paste as the machine does not boot anymore. Can anyone give me some help or can explain to me what other kind of info you need? Thanks. --- Kind regards Felix -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
