Problem:
Activation of share quotas fails with an error message:
Aktivierung der Quota-Unterstützung ist fehlgeschlagen: Erstellung der
Quota-Informationsdatei ist fehlgeschlagen
Activation of the quota support failed: Creation of
Quota information file failed
Solution
Make sure there are no open files on the destination folder (verify by using lsof) and run the commands (here /home):
quotaoff /home
quotacheck -ucv /home
quotaon /home
