Question

Come posso evitare che uno script di shell pianificato contenente un comando rsync provochi un panico del kernel?

Ho un semplice script di shell di backup che viene eseguito ogni giorno alle 1:00. Usa rsync per copiare dodici diverse directory sul disco rigido esterno del mio computer Windows. Ecco un esempio:

rsync -a --delete-after --progress --stats "$HOME/Downloads" "/Volumes/Backups/MacBook Pro"

Funzionava benissimo, ma un giorno il kernel è entrato nel panico. Quindi il giorno dopo. E poi il prossimo. Ho risolto alcuni problemi e ho scoperto che il panico del kernel si verifica solo quando la directory "$ HOME / Documents" è inclusa nell'elenco delle directory di cui eseguire il backup. Ma ecco la cosa bizzarra: se eseguo lo script di backup manualmente, lo script esegue tutto senza il panico del kernel. Qualche idea? Ecco il rapporto:

score 1 · Answer 1

Ho notato che hai caricato kBox VirtualBox. Presumo che tu abbia una macchina virtuale in esecuzione durante il backup. Negli ultimi mesi ho avuto panico del kernel (per nulla coerente come il tuo), da diverse app, ma alla fine ho capito che si verificano solo se ho VM in esecuzione e un carico elevato della CPU (come creerebbe rsync).

Non ho idea del perché ancora, ma probabilmente potresti testarlo sul tuo sistema.

Il tuo comando rsync sembra OK. In secondo luogo, il commento dice che dovresti usare launchd piuttosto che cron . Più pulito, più affidabile e una volta creato il plist nel posto giusto, non dovrai preoccuparti di eseguire accidentalmente come root.

C'è una bella app chiamata Lingon che fornisce una GUI per launchd . Molto bello con cui lavorare, anche se sei disposto a modificare manualmente i file plist.

Inoltre, assicurati che la shell specificata nella parte superiore dello script sia uguale alla shell che stai utilizzando in Terminal. Dubbi che è così, ma non si sa mai.
