Buon pomeriggio a tutti.
alcuni giorni fa il mio bravissimo nipote tra i fumi dell'alcool invece di andarsene a dormire a casa sua ha visto bene di approfittare del letto vuoto dello zio all'estero, non riuscendo ad addormentarsi causa pc accesi, ha sconnesso brutalmente la presa di alimentazione delle ciabatte e spento il gruppo di continutà che bippava.
Dal momento che le disgrazie spesso vengono in coppia come i carabinieri, non solo si è corrotto il filesystem ma si è acciaccato di brutto l'hdd. (non inveite, stavo aspettando di rimettere il gemello nell'lvm, ma vista la mancanza di cervelli nella mia zona lo volevo fare di persona, e ancora non ho trovato il modo di farlo dal brasile).
quindi la situazione è questa.
eseguito l'fsck con opzione y da un mio amico guidato in remoto. il pc parte ma la gran parte dei servizi non parte.
dal log messages
vedo i seguenti output:

Selective self-test flags (0x0):
After scanning selected spans, do NOT read-scan remainder of disk.
If Selective self-test is pending on power-up, resume after 0 minute delay.
quindi dai precedenti messaggi ne deduco che l'hdd è sull'orlo del precipizio e comunque la smebox inservibile al 90%.
la versione installata:
[root@server ~]# cat /etc/e-smith-release
SME Server release 8.1
quindi le prima domande sono le seguenti, è consigliabile in forzare in qualche modo un nuovo controllo del filesystem?
posso in qualche modo da remoto eseguire qualche riparazione sulla superficie del disco, visto che le partizioni sono montate? fsck e badblocks...
è possibile su sme 8.1 per esempio passare il comando nella riga di avvio del kernel come su altre distro?
es:
fsck.mode=force fsck.repair=yes
oppure passare l'opzione "y" usando il flag di controllo /forcefsck ??
detto questo,
nella necessità quindi di sostituire i dischi..
posso ancora accedere e copiare manualmente la configurazione su un disco usb, con il dubbio che i files siano corrotti
e comunque ho un set intero di backup fatto con affa di poco precedente all'evento cosmico.
quindi mi domando, funziona il ripristino di affa su una fresh installed smebox 9.1 ?? dal momento che ho letto che le differenze son molte tra le due versioni.
thanks
