I had a "robust read" patch in FR1, and I thought Neil extended that to "robust write". In robust read, we try to make up for a failed read with info from elsewhere, and then we rewrite the inferred data onto the failed device, in an attempt to fix a possible defect. In robust write, a failed write is retried. But robust read is enough to cause a retry (as a write). > It does write-back as a (very successful!

Plozzziby. > Or is there something sandwiched between MD and ENBD that performs retries... Could be too. Dunno.
