After a reboot bcache didn't start automatically. So I stopped bcache, unloaded the module, reloaded it and tried to register the SSD and HDD again. Registering the SSD gave me this error: error on f1e69e99-940d-447a-900e-4956bd607933: unsupported bset version at bucket 108098, block 0, 855650560 keys, disabling caching The bcache was running in writeback mode but I think it was almost clean so I forced the device to go online and made an fsck. Everything looks ok, so no data loss. But surely this should not happen, right? Is there any way to check why? (I made an image of the cache device) Kernel is 3.10.7; setup with "make-bcache -C -w 512 /dev/sdb2" and "make-bcache -B -w 512 /dev/sda2 --data-offset=2048" Regards Tobias
