Sanibonani.
Bengifuna ukudonsa ukunaka komphakathi isici se-Linux lapho ngisebenza nama-NVMe SSD amaningi ohlelweni olulodwa. Kuzoba usizo ikakhulukazi kulabo abathanda ukwenza isoftware ye-RAID arrays kusuka ku-NVMe.
Ngithemba ukuthi ulwazi olungezansi luzosiza ukuvikela idatha yakho futhi lususe amaphutha acasulayo.
Sonke sijwayele i-logic ye-Linux elandelayo lapho sisebenza ngamadivayisi we-block:
Uma idivayisi ibizwa ngokuthi /dev/sda bese izingxenye ezikuyo zizoba ngu/dev/sda1,/dev/sda2, njll.
Ukubuka izibaluli ze-SMART, sisebenzisa okuthile okufana ne-smartctl -a /dev/sda, futhi siyifomethe futhi sengeze ukwahlukanisa kumalungu afanayo, njenge /dev/sda1.
Sonke sijwayele i-axiom ethi /dev/sda1 itholakala ku/dev/sda. Futhi, uma ngolunye usuku i-SMART ikhombisa ukuthi/i-dev/sda isicishe yafa, ngu/dev/sda1 lapho sizokhipha kuhlelo lwe-RAID ukuze kushintshwe.
Kuvele ukuthi lo mthetho awusebenzi uma usebenza ne-NVMe Namespaces. Ubufakazi:
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
/dev/nvme2n1 S466NX0K72XX01A Samsung SSD 970 EVO 500GB 1 0.00 B / 500.11 GB 512 B + 0 B 1B2QEXE7
Serial Number: S466NX0K72XX06M
Serial Number: S466NX0K72XX01A
Serial Number: S466NX0K43XX48W
Umfundi ohlakaniphile wokuqhathaniswa kwenombolo ye-serial uzoqaphela ukuthi /dev/nvme1n1 empeleni itholakala ku/dev/nvme2, futhi ngokuphambene nalokho.
I-P.S.
Ngifisa sengathi ungalokothi ususe i-NVMe SSD yokugcina ephilayo ohlwini lwe-RAID.
