O dara ọjọ.
Mo fẹ lati fa ifojusi agbegbe si ẹya abuda ti Linux nigbati o n ṣiṣẹ pẹlu awọn NVMe SSD pupọ ninu eto kan. Yoo jẹ pataki ni pataki fun awọn ti o nifẹ lati ṣe awọn eto RAID sọfitiwia lati NVMe.
Mo nireti pe alaye ti o wa ni isalẹ yoo ṣe iranlọwọ lati daabobo data rẹ ati imukuro awọn aṣiṣe didanubi.
Gbogbo wa ni deede si imọran Linux atẹle nigba ṣiṣẹ pẹlu awọn ẹrọ dina:
Ti a ba pe ẹrọ naa / dev/sda lẹhinna awọn ipin lori rẹ yoo jẹ / dev/sda1, /dev/sda2, ati bẹbẹ lọ.
Lati wo awọn abuda SMART, a lo nkan bii smartctl -a /dev/sda, ati ṣe ọna kika rẹ ati ṣafikun awọn ipin si awọn akojọpọ, bii /dev/sda1.
Gbogbo wa ni a mọ si axiom pe /dev/sda1 wa lori /dev/sda. Ati pe, ti o ba jẹ pe ọjọ kan SMART fihan pe / dev / sda ti fẹrẹ ku, o jẹ / dev / sda1 ti a yoo jabọ kuro ni ipilẹ RAID fun rirọpo.
O wa ni pe ofin yii ko ṣiṣẹ nigbati o ba n ṣiṣẹ pẹlu Awọn aaye Orukọ NVMe. Ẹri:
nvme list && ( smartctl -a /dev/nvme0 && smartctl -a /dev/nvme1 && smartctl -a /dev/nvme2 ) | grep Serial

Oluka ti o ni oye ti lafiwe nọmba ni tẹlentẹle yoo ṣe akiyesi pe / dev/nvme1n1 wa lori / dev/nvme2, ati ni idakeji.
P.S.
Mo fẹ ki o ko yọ NVMe SSD ti o kẹhin kuro ni titobi RAID.
