Kyakkyawan lokaci na rana.
Ina so in jawo hankalin al'umma zuwa fasalin fasalin Linux lokacin aiki tare da NVMe SSDs da yawa a cikin tsarin ɗaya. Zai zama dacewa musamman ga waɗanda suke son yin tsarin RAID na software daga NVMe.
Ina fatan bayanin da ke ƙasa zai taimaka kare bayanan ku kuma ya kawar da kurakurai masu ban haushi.
Dukanmu mun saba da waɗannan dabaru na Linux yayin aiki tare da na'urorin toshe:
Idan ana kiran na'urar / dev/sda to sassan da ke kanta za su kasance /dev/sda1, /dev/sda2, da dai sauransu.
Don duba halayen SMART, muna amfani da wani abu kamar smartctl -a /dev/sda, da tsara shi kuma mu ƙara ɓangarori zuwa tsararrun, kamar /dev/sda1.
Dukkanmu mun saba da axiom cewa /dev/sda1 yana kan /dev/sda. Kuma, idan wata rana SMART ya nuna cewa / dev / sda ya kusan mutu, shine / dev / sda1 da za mu jefa daga cikin tsarin RAID don maye gurbin.
Ya bayyana cewa wannan doka ba ta aiki yayin aiki tare da NVMe Namespaces. Hujja:
nvme list && ( smartctl -a /dev/nvme0 && smartctl -a /dev/nvme1 && smartctl -a /dev/nvme2 ) | grep Serial
Node SN Model Namespace Usage Format FW Rev

/dev/nvme0n1 S466NX0K72XX06M Samsung SSD 970 EVO 500GB 1 96.92 GB / 500.11 GB 512 B + 0 B 1B2QEXE7

Serial Number: S466NX0K72XX06M
Serial Number: S466NX0K72XX01A
Serial Number: S466NX0K43XX48W
haziki mai karatu na kwatanta lambar serial zai lura cewa /dev/nvme1n1 yana kan /dev/nvme2, kuma akasin haka.
P.S.
Ina fata ba za ku taɓa cire NVMe SSD mai rai na ƙarshe daga tsararrun RAID ba.
