Dobry den,

Je mi divne, ze raid nahlasil disk ad8 jako datached a pole jako DEGRADED,
kdyz ihned po rebootu se zobrazil jeho stav READY a je tomu tak I nyni?.
A jeste  me desi hlaska TIMEOUT - WRITE_DMA48.

Jde z tohoto usoudit ce se stalo? Spatny disk,board?
Je normalni, ze na se sytem rebootne?

 V te chvily se na pole ar1 kopiroval nejaky velky backup.


Dekuji
