The core is careful to +avoid asking about anything that is migrating. This is a pain, but +makes it easier to write the policies. + +Mappings are loaded into the policy at construction time. + +Every bio that is mapped by the target is referred to the policy. +The policy can return a simple HIT or MISS or issue a migration. + +Currently there's no way for the policy to issue background work, +e.g. to start writing back dirty blocks that are going to be evicte +soon. + +Because we map bios, rather than requests it's easy for the policy +to get fooled by many small bios. For this reason the core target +issues periodic ticks to the policy. It's suggested that the policy +doesn't update states (eg, hit counts) for a block more than once +for each tick. The core ticks by watching bios complete, and so +trying to see when the io scheduler has let the ios run. + + +Overview of supplied cache replacement policies +=============================================== + +multiqueue +---------- + +This policy is the default. + +The multiqueue policy has two sets of 16 queues: one set for entries +waiting for the cache and another one for those in the cache. +Cache entries in the queues are aged based on logical time. Entry into +the cache is based on variable thresholds and queue selection is based +on hit count on entry. The policy aims to take different cache miss +costs into account and to adjust to varying load patterns automatically. + +Message and constructor argument pairs are: + 'sequential_threshold <#nr_sequential_ios>' and + 'random_threshold <#nr_random_ios>'. + +The sequential threshold indicates the number of contiguous I/Os +required before a stream is treated as sequential. The random threshold +is the number of intervening non-contiguous I/Os that must be seen +before the stream is treated as random again. + +The sequential and random thresholds default to 512 and 4 respectively. + +Large, sequential ios are probably better left on the origin device +since spindles tend to have good bandwidth.

Caching solutions that are integrated more +closely with the virtual memory system should give better performance. + +The target reuses the metadata library used in the thin-provisioning +library. + +The decision as to what data to migrate and when is left to a plug-in +policy module. Several of these have been written as we experiment, +and we hope other people will contribute others for specific io +scenarios (eg. a vm image server). + +Glossary +======== + + Migration - Movement of the primary copy of a logical block from one + device to the other. + Promotion - Migration from slow device to fast device. + Demotion - Migration from fast device to slow device. + +The origin device always contains a copy of the logical block, which +may be out of date or kept in sync with the copy on the cache device +(depending on policy). + +Design +====== + +Sub-devices +----------- + +The target is constructed by passing three devices to it (along with +other parameters detailed later): + +1. An origin device - the big, slow one. + +2. A cache device - the small, fast one. + +3. A small metadata device - records which blocks are in the cache, + which are dirty, and extra hints for use by the policy object. + This information could be put on the cache device, but having it + separate allows the volume manager to configure it differently, + e.g. as a mirror for extra robustness. + +Fixed block size +---------------- + +The origin is divided up into blocks of a fixed size. This block size +is configurable when you first create the cache. Typically we've been +using block sizes of 256k - 1024k. + +Having a fixed block size simplifies the target a lot. But it is +something of a compromise. For instance, a small part of a block may be +getting hit a lot, yet the whole block will be promoted to the cache. +So large block sizes are bad because they waste cache space. And small +block sizes are bad because they increase the amount of metadata (both +in core and on disk). + +Writeback/writethrough +---------------------- + +The cache has two modes, writeback and writethrough. + +If writeback, the default, is selected then a write to a block that is +cached will go only to the cache and the block will be marked dirty in +the metadata. + +If writethrough is selected then a write to a cached block will not +complete until it has hit both the origin and cache devices. Clean +blocks should remain clean. + +A simple cleaner policy is provided, which will clean (write back) all +dirty blocks in a cache. Useful for decommissioning a cache. + +Migration throttling +-------------------- + +Migrating data between the origin and cache device uses bandwidth. +The user can set a throttle to prevent more than a certain amount of +migration occuring at any one time. Currently we're not taking any +account of normal io traffic going to the devices. More work needs +doing here to avoid migrating during those peak io moments. + +For the time being, a message "migration_threshold <#sectors>" +can be used to set the maximum number of sectors being migrated, +the default being 204800 sectors (or 100MB). + +Updating on-disk metadata +------------------------- + +On-disk metadata is committed every time a REQ_SYNC or REQ_FUA bio is +written. If no such requests are made then commits will occur every +second. This means the cache behaves like a physical disk that has a +write cache (the same is true of the thin-provisioning target). If +power is lost you may lose some recent writes. The metadata should +always be consistent in spite of any crash. + +The 'dirty' state for a cache block changes far too frequently for us +to keep updating it on the fly. So we treat it as a hint. In normal +operation it will be written when the dm device is suspended. If the +system crashes all cache blocks will be assumed dirty when restarted. + +Per-block policy hints +---------------------- + +Policy plug-ins can store a chunk of data per cache block. It's up to +the policy how big this chunk is, but it should be kept small. Like the +dirty flags this data is lost if there's a crash so a safe fallback +value should always be possible. + +For instance, the 'mq' policy, which is currently the default policy, +uses this facility to store the hit count of the cache blocks. If +there's a crash this information will be lost, which means the cache +may be less efficient until those hit counts are regenerated. + +Policy hints affect performance, not correctness. + +Policy messaging +---------------- + +Policies will have different tunables, specific to each one, so we +need a generic way of getting and setting these. Device-mapper +messages are used. Refer to cache-policies.txt. + +Discard bitset resolution +------------------------- + +We can avoid copying data during migration if we know the block has +been discarded. A prime example of this is when mkfs discards the +whole block device. We store a bitset tracking the discard state of +blocks. However, we allow this bitset to have a different block size +from the cache blocks. This is because we need to track the discard +state for all of the origin device (compare with the dirty bitset +which is just for the smaller cache device). + +Target interface +================ + +Constructor +----------- + + cache + <#feature args> []* + <#policy args> [policy args]* + + metadata dev : fast device holding the persistent metadata + cache dev : fast device holding cached data blocks + origin dev : slow device holding original data blocks + block size : cache unit size in sectors + + #feature args : number of feature arguments passed + feature args : writethrough.
