Hi guys, I want to know if dm writecache target can handle power-off situation.
I've read the dm-writecache.c recent days and got confused. It seems that dm writecache may lose data if my pc encounter a power-off. Here is my thought: 1. There is no replay process for dm writecache. Every time writecache_ctr() builds a new wc_memory_entry array. 2. metadata update in dm-writeback can not guarantee atomic. If I missed something? Thanks
