Error "unsupported bset version"
Hi all,
I'm running bcache to speed up my 4 TB HDD with a 64 GB partition on my SSD. 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

I think this was the result of a bug for which I accidentally didn't mark the fix for stable - the fix was in 3.11
I just sent out a pull request to get it into 3.10, and in the meantime I have a branch with all the relevant fixes on top of 3.10:
