Maalin wacan.
Waxaan rabay inaan soo jiito dareenka bulshada sifo sifo ah Linux markii aan la shaqeynayo NVMe SSDs badan oo hal nidaam ah. Waxay si gaar ah u khusayn doontaa kuwa jecel inay ka sameeyaan barnaamijyada RAID-yada ee NVMe.
Waxaan rajeynayaa in xogta hoose ay kaa caawin doonto ilaalinta xogtaada oo ay tirtirto khaladaadka xanaaqa.
Dhammaanteen waxaan la qabsannay caqli-galka Linux ee soo socda markaan la shaqeyneyno aaladaha xannibaadda:
Haddii aaladda loo yaqaan / dev/sda markaas qaybaha ku yaal waxay noqon doonaan / dev/sda1, / dev/sda2, iwm.
Si aan u aragno sifooyinka SMART, waxaan isticmaalnaa wax sida smartctl -a /dev/sda, waana qaabeynaa oo aan ku darnaa qaybo ka mid ah arraysyada, sida /dev/sda1.
Dhammaanteen waxaan la qabsannay axiom-ka /dev/sda1 ku yaal /dev/sda. Iyo, haddii hal maalin SMART ay muujiso in /dev/sda ay ku dhowdahay inay dhimato, waa /dev/sda1 inaan ka tuurno RAID aray si loogu beddelo.
Waxay soo baxday in xeerkani aanu shaqaynayn markaad la shaqaynayso NVMe Namespaces. Cadayn:
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
Akhristaha xikmad leh ee isbarbardhigga lambarka taxanaha ayaa ogaan doona in /dev/nvme1n1 ay dhab ahaantii ku taallo /dev/nvme2, iyo lidkeeda.
P.S.
Waxaan jeclaan lahaa inaadan waligaa ka saarin NVMe SSD ee ugu dambeeyay ee noolasha RAID.
