Does dm-thin support GC (garbage collection) ?
|[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]|
Hi All, The dm-thin supports 'discard' now?Can I think this function likes SSD's 'TRIM'? If it just discard the block mapped but not remap(reallocate), the Pool's space will soon be used up . I want to know whether it supports block reuse ( can use ext4 with '--discard' test this? ) now or in the future. Thanks.
