[RFE] - Set "blkdiscard" as the default zero method
Last modified: 2017-09-19 03:59:30 EDT
I think this is 'blkdiscard --zero' option here.
When we support just 'blkdiscard' (if the storage promises to return zeros on discarded blocks), it's a different option, no?
Yes, but since we're talking about the config value "zero_method" (see Bug 1367806), the option name is "blkdiscard".
I will open a new BZ to track the second RFE you implied to, i.e when the user removes a disk with an intention to zero and discard it, and the underlying storage support discard_zeroes_data, then the disk is only discarded (and not wiped).
This depends on the scale's team ability to prove this method is safe.
