Bon jou.
Mwen te vle atire atansyon kominote a sou yon karakteristik karakteristik Linux lè w ap travay ak plizyè SSD NVMe nan yon sèl sistèm. Li pral espesyalman enpòtan pou moun ki renmen fè etalaj RAID lojisyèl soti nan NVMe.
Mwen espere ke enfòmasyon ki anba a pral ede pwoteje done ou yo ak elimine erè anmèdan.
Nou tout abitye ak lojik Linux sa a lè w ap travay ak aparèy blòk:
Si yo rele aparèy la /dev/sda, patisyon ki sou li yo pral /dev/sda1, /dev/sda2, elatriye.
Pou wè atribi SMART, nou itilize yon bagay tankou smartctl -a /dev/sda, epi fòme li epi ajoute patisyon nan etalaj yo, tankou /dev/sda1.
Nou tout abitye aksyòm ke /dev/sda1 sitiye sou /dev/sda. Epi, si yon jou SMART montre ke /dev/sda prèske mouri, se /dev/sda1 ke nou pral jete nan etalaj RAID la pou ranplasman.
Li sanble ke règ sa a pa travay lè w ap travay ak NVMe Namespaces. Prèv:
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
Yon lektè rize nan konparezon nimewo seri a pral remake ke /dev/nvme1n1 aktyèlman sitiye sou /dev/nvme2, ak vis vèrsa.
P.S.
Mwen swete ou pa janm retire dènye SSD NVMe vivan an nan etalaj RAID la.
