Field Documentation

pvf_allowance

uint32_t pvf_allowance[M0_CONF_PVER_HEIGHT]

Allowance vector — the number of objects excluded from the corresponding level of base pver subtree.

Difference between allowance and tolerance: allowance is for writing, i.e. we will create new pool versions until that number of failures is reached. Tolerance is for reading.

Precondition

at least one of the numbers != 0

Definition at line 512 of file obj.h.

pvf_base

struct m0_fid pvf_base

Fid of the base pool version.

Base pver is the "actual" pver, which a "virtual" pver is modelled after.
