5925 zfs receive -o origin= Reviewed by: Prakash Surya <prakash.surya@delphix.com> Reviewed by: Matthew Ahrens <mahrens@delphix.com> Author: Paul Dagnelie <pcd@delphix.com> While running 'zfs recv' we noticed that every 128th 8K block required a read. We were seeing that restore_write() was calling dmu_tx_hold_write() and the indirect block was not cached. We should prefetch upcoming indirect blocks to avoid having to go to disk and blocking the restore_write(). Allow an incremental send stream to be received as a clone, even if the stream does not mark it as a clone. |
