Symptoms

Impossibile eseguire l'aggiornamento di OneFS a causa della mancanza di spazio nel file system /var di uno dei nodi.

Il nodo mostra il seguente utilizzo dei file system: 
# df -h

Lo spazio utilizzato è superiore a 700 Mbyte, ma non è possibile trovare file con più di 200 Mbyte: 
# du -sh /var/crash
 13M    /var/crash

# du -sh /var
201M    /var

Ho provato a smontare /var/crash e ho guardato se ci sono file in /var/crash ma non è stato trovato nulla.

Cause

File orfani eliminati ma senza recuperare spazio.

Resolution

Riavviare il nodo per recuperare spazio. Dopo il riavvio, è presente il seguente utilizzo del file system: 
# df -h
Filesystem               Size    Used   Avail Capacity  Mounted on
/dev/mirror/root0        956M    475M    404M    54%    /
