We have a use case where HDDs are regularly power on/off to perserve power. When a drive is being removed, we often see errors like [ 172.803279] I/O error, dev sda, sector 3137184 These messages are confusing for automations that grep dmesg, as they look very similar to real HDD error. Solve this issue with a new block state BLK_STS_OFFLINE. After the change, the error message looks like [ 172.803279] device offline error, dev sda, sector 3137184 so that the automations won't confuse them with real I/O error.
