Then try to create a test directory with the next project id and set a quota on it. If that works, continue to scan existing containers to map allocated project ids.

func (*Control) ClearQuota ¶

func (q *Control) ClearQuota(targetPath string)

ClearQuota removes the map entry in the quotas map for targetPath. It does so to prevent the map leaking entries as directories are deleted.

func (*Control) GetQuota ¶

func (q *Control) GetQuota(targetPath string, quota *Quota) error

GetQuota - get the quota limits of a directory that was configured with SetQuota

func (*Control) SetQuota ¶

func (q *Control) SetQuota(targetPath string, quota Quota) error

SetQuota - assign a unique project id to directory and set the quota limits for that project id. targetPath must exist, must be a directory, and must be empty.

type Quota ¶

type Quota struct {
	Size   uint64
	Inodes uint64
}

Quota limit params - currently we only control blocks hard limit and inodes
