[ClusterLabs] Antw: Re: Antw: Re: Antw: DRBD and SSD TRIM - Slow! -- RESOLVED!

Hi! Thanks for sharing your interesting insights! I have no idea how the trimming works, but I can imagine if you try to trim a portion that is smaller than the managed size (assuming it does not fail) may cause the rest of the data to be migrated to a new block before the old block is
