Spiegazione
Il file system cyc_fs viene utilizzato per archiviare i materiali di supporto, i file diagnostici e lo spazio utilizzato da questi viene normalmente gestito automaticamente. In alcune rare occasioni, troppi materiali di supporto sono stati mantenuti, causando una scarsa disponibilità di spazio libero nel cyc_fs.
Resolution
Utilizzare l'interfaccia utente di PowerStore Manager o lo script della shell del servizio svc_dc per rimuovere le raccolte di dati meno recenti e liberare spazio nell cyc_fs.
