Description

fast_read

Description:    On Erasure Coding pool, if this flag is turned on, the read request would issue sub reads to all shards, and waits until it receives enough shards to decode to serve the client. In the case of jerasure and isa erasure plugins, once the first K replies return, client’s request is served immediately using the data decoded from these replies. This helps to tradeoff some resources for better performance. Currently this flag is only supported for Erasure Coding pool.
Type:    Boolean
Defaults:    0

It should be Integer (FastReadType https://github.com/ceph/ceph/blob/17376dbff64e4d9960276d483f9297955c60ffd9/src/mon/OSDMonitor.h#L159).

This bug has been judged too old to fix. This is because either it is either 1) raised against a version of Ceph prior to Luminous, or 2) just really old, and untouched for so long that it is unlikely nowadays to represent a live documentation concern.

If you think that the closing of this bug is an error, raise another bug of a similar kind. If you think that the matter requires urgent attention, please let Zac Dover know at .
