Tere p\u00e4evast.<\/p>\n

Soovin juhtida kogukonna t\u00e4helepanu Linuxi erip\u00e4ra peale, kui mitme NVMe SSD-ga \u00fches s\u00fcsteemis t\u00f6\u00f6tada. See on eriti oluline neile, kes armastavad luua NVMe programmilisi RAID-mahuteid.<\/p>\n

Loodan, et allpool toodud teave aitab kaitsta teie andmeid ja vabastab t\u00fc\u00fctutest vigadest.

\nMe k\u00f5ik oleme harjunud j\u00e4rgmise loogikaga Linuxis plokkseadmete kasutamisel:
\nKui seade on nimega \/dev\/sda, siis sellel olevad partitsioonid on \/dev\/sda1, \/dev\/sda2 jne.
\nSMART-i atribuute vaatamiseks kasutame midagi sellist nagu smartctl -a \/dev\/sda, ning formaadime ja lisame massiividesse juba partitsioonid, n\u00e4iteks \/dev\/sda1.<\/p>\n

Me k\u00f5ik oleme harjunud aksioomiga, et \/dev\/sda1 asub \/dev\/sda peal. Ja kui \u00fchel p\u00e4eval SMART n\u00e4itab, et \/dev\/sda on peaaegu surnud, siis just \/dev\/sda1 viskame RAID-mahuti asenduseks v\u00e4lja.<\/p>\n

Selgub, et NVMe nimede ruumidega t\u00f6\u00f6tamisel see reegel ei kehti. T\u00f5end:<\/p>\n
