Αργό boot (ubuntu 12.04)

Thu May 30 13:05:17 EEST 2013

καλό το bootchart.
H πρώτη εικόνα που παραθέτω είναι όπως ήταν το σύστημα.
Φαίνεται ότι η καθυστέρηση γίνεται από την fsck ... όμως όχι γιατί κάνει 
κάτι, αλλά γιατί γίνεται blocked.

βρήκα αντίστοιχες περιπτώσεις (όπως στην σελίδα 
http://askubuntu.com/questions/39316/slow-boot-after-clean-install-of-natty).
Ακολουθώντας τις εκεί οδηγίες
και διαγράφοντας την γραμμή στο
/lib/udev/rules.d/60-persistent-storage.rules όπως περιγράφεται, έκανε 
χειρότερη την κατάσταση..... (εικόνα2 :-)

Όμως απ-εγκαθιστώντας το ureadahead,
*μετά σβήνεις τα αρχεία στο **
**/var/lib/ureadahead/* και ξανά εγκατασταση του ureadahead και 
reboot... και reboot βελτίωσε την κατάσταση.

Νομίζω ότι η καθυστέρηση που έμεινε είναι φυσιολογική. :-)

Παρόλα αυτά έχω έναν μικρό ενδοιασμό για την εικόνα που βγάζει το 
bootchart, διότι δεν συμφωνούν
οι χρόνοι με αυτούς που δείχνει το dmesg....
Δεν πειράζει... ας το ψάξουμε άλλη φορά .
