Dotaz: USB disk - zálohování

[Petr]

Zdravím,

k serveru mám připojený 1TB USB disk. Zálohuju na něj data serveru. Zároveň mám tento disk zpřístupněný přes Sambu, kvůli zálohování svého PC s Win 7. Vše až donedávna fungovalo naprosto v pořádku, nicméně teď se začlo dít to, že když se sputí zálohování dat na mé stanici s Win 7, záloha probíhá a nejednou se server zakousne. V logu se objeví níže uvedené hlášky. Jediné co pomůže je natvrdo odpojit disk, server se vzpamatuje, připojit disk, namountovat a restartovat sambu. Nevíte, kde by mohl být problém?

Díky moc

Odpovědi

[Sten]

Disk je zřejmě vážně poškozen, tipuji to na vadné sektory. Připojil bych jej k nějakému počítači a nechal prohlédnout přes SMART.

[Petr]

Děkuji za reakci. Také jsem došel k tomuto závěru, nicméně ten disk jsem zkusil na pár dní vytáhnout, připojit přímo přes USB k mému PC a tam šlapal jak hodinky. Takže nevím. Zkusím tedy ten SMART.

[Petr]

Aha, tak tudy cesta zřejmě nepovede, viz níže:

Problém bude v připojení na usb, připoj disk přímo na kabel. (SMART se s USB nekamarádí.)

Přesně tak, tím to není.

Co myslíte tím připojit disk přímo na kabel? Toto je USB disk.

[dustin]

Ale vevnitř je normální SATA disk :)

kuk http://www.micro-isv.asia/photos/J6145742.jpg

[Petr Šobáň]

To znamená rozšroubovat a disk vytáhnout a připojit přímo do PC na řadič.

[Petr]

Aha, tak to me nenapadlo Diky moc. Zkusim s tim neco co nejdrive provest a pak dam vedet.

[Peter Golis]

hdparm má v sebe rannú podporu aj pre tunelovanie S.M.A.R.T príkazov cez USB prevodníky. Len je mu to treba vnútiť cez parameter.

[luta]

já USB disky normálně vyčítám přes gsmartcontrol.. se smartctl neumím nastavit parametry aby to komunikovalo a píše mi to to co Vám, ale s gsmartcontrol mi to kupodivu jde se všemi boxy co jsou založeny na jmicron chipsetech
