More detailed information on flushing write cache data
Posted: Thu Nov 15, 2018 4:02 pm
I have currently one server with 2 TByte read/write cache and one server with 480 GB Optane read/write cache.
When ending the software or flushing the cache, I can only see a running bar with no start/end, so it's hard to tell how long it will take. And believe me - it takes a serious amount of time. We are talking about 1/4 TByte or more typically.
Given that you know exactly how many blocks you need to flush to disk, couldn't you add a more detailed display such as:
m of n total blocks written
m*blocksize/x seconds [B/s, KB/s, MB/s, GB/s] written
x seconds taken, y seconds to go (prediction)
a true progress bar in %
That would be very welcome and - by the way - feel much safer when you really see it writing all data through to the end.
Cheers
