Well, what I did was: - Take out sdg. - Reformat both caching and backing devices and started over. I still have the kernel logs of the previous fault condition, but not the data anymore. What I notice are: - The 100% CPU usage for four bcache_writebac processes is back. I've already tried raising the value you suggested from 30 to 60, but I did not have an opportunity to reboot yet. Will report back on this. - When I run bcache-super-show on the backing devices, it works just fine. - When I run bcache-super-show on the caching devices (while in service) I get something like this: sb.magic ok sb.first_sector 8 [match] sb.csum FFFFFFFF5D55BF8D [expected 726D3B42D08769EC] Corrupt superblock (bad csum) On both caching devices. Is this to be expected? -- Stephen. -- To unsubscribe from this list: send the line "unsubscribe linux-bcache" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
