Re: Wapbl correct and stable again?



I have no "discard" parameters in my fstab. All wapbl FSs are mounted rw,log.

Can you confirm whether you had the filesystem mounted with 'discard'

FYI, discard hides block deallocation changes from wapbl log until
discard is finished for the blocks, so pretty much throws consistency
out of window. I plan to actually change FFS to disable discard when
logging is enabled as stopgap measure, because of this. Later, discard
needs to be changed, so that it doesn't interfere with block free
maps.
