Detailed Description

Enumeration Type Documentation

sns_repair_state

enum sns_repair_state

State of SNS repair with respect to given global fid. Used during degraded mode write IO. During normal IO, the UNINITIALIZED enum value is used. The next 2 states are used during degraded mode write IO.

Enumerator
SRS_UNINITIALIZED	Used by IO requests done during healthy state of storage pool. Initialized to -1 in order to sync it with output of API m0_sns_cm_fid_repair_done().
SRS_REPAIR_NOTDONE	Assumes a distributed lock has been acquired on the associated global fid and SNS repair is yet to start on given global fid.
SRS_REPAIR_DONE	Assumes a distributed lock has been acquired on associated global fid and SNS repair has completed for given fid.
SRS_NR
