Nenguva yezuva.
Ini ndaida kukwevera kutarisisa kwenharaunda kune hunhu hweLinux kana uchishanda neakawanda maNVMe SSD mune imwe system. Ichanyanya kukosha kune avo vanoda kugadzira software RAID arrays kubva kuNVMe.
Ndinovimba kuti ruzivo rwuri pazasi ruchabatsira kuchengetedza data rako uye kubvisa zvikanganiso zvinoshungurudza.
Isu tese takajairira kune inotevera Linux mantiki kana tichishanda ne block zvishandiso:
Kana iyo kifaa ichinzi / dev / sda ipapo zvikamu pairi zvichave / dev / sda1, / dev / sda2, nezvimwe.
Kuona SMART hunhu, isu tinoshandisa chinhu senge smartctl -a /dev/sda, uye toifometa uye nekuwedzera zvikamu kune arrays, senge /dev/sda1.
Isu tese takajaira axiom iyo /dev/sda1 iri pa/dev/sda. Uye, kana rimwe zuva SMART ichiratidza kuti / dev/sda inenge yafa, iri / dev/sda1 yatichakanda kunze kweRAID array yekutsiva.
Zvinoitika kuti mutemo uyu haushande kana uchishanda neNVMe Namespaces. Humbowo:
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
/dev/nvme1n1 S466NX0K43XX48W Samsung SSD 970 EVO 500GB 1 91.00 GB / 500.11 GB 512 B + 0 B 1B2QEXE7

Serial Number: S466NX0K72XX06M
Serial Number: S466NX0K72XX01A
Serial Number: S466NX0K43XX48W
Muverengi akangwara weiyo serial nhamba yekuenzanisa anozoona kuti /dev/nvme1n1 iri chaizvo pa/dev/nvme2, uye zvinopesana.
PS
Ndinoshuva kuti usambobvisa iyo yekupedzisira inorarama NVMe SSD kubva kuRAID array.
