Nebude to tymto? http://linux-raid.osdl.org/index.php/Mdstat Personalities line The "Personalities" line tells you what RAID level the kernel currently supports. This can be changed by either changing the raid modules or recompiling the kernel. Possible personalities include: [raid0] [raid1] [raid4] [raid5] [raid6] [linear] [multipath] [faulty]
Note: [faulty] is a diagnostic personality; it does not mean there is a problem with the array. [edit]

[Ivanhoej]

Takze to bude ok a ako sa toho stavu zbavit?

[AraxoN]

To nie je stav, to je len vymenovanie toho, čo všetko je ku RAIDu v jadre skompilované, resp. nahrané ako modul.

CONFIG_MD_FAULTY:


The "faulty" module allows for a block device that occasionally returns read or write errors.  It is useful for testing.

In unsure, say N.

[Ivanhoej]

Aha, takze fajn nie je sa coho obavat, dik moc.

Rozhodně ale není radno něco odsouhlasit bez pořádného přečtení
