[dm-devel] [PATCH 1/6] dm cache: cache shrinking support

[Alasdair G Kergon]

> DMERR("unable to shrink cache due to dirty blocks");

Also, what is the process to recover from this error, given that you have
already lost the end of the device and you cannot now resume the device
without a preresume failure?

Do the tools support retrieval of the dirty blocks from the portion of the
device that you do still have?
