Description

It is possible to set the profile on a per layer basis using the low level configuration http://ceph.com/docs/master/rados/operations/erasure-code-lrc/#erasure-code-profile-examples-using-low-level-configuration . The second argument in layers='[ [ "DDc", "" ] ]' is actually an erasure code profile to be used for this level. You can change it to layers='[ [ "DDc", "plugin=isa technique=reed_sol_van" ] ]' to select the isa plugin with the Reed Solomon Vandermonde technique.

It needs to be documented.

  • Status changed from New to Closed

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 .
