Uhlobo lomhla.
Ndandifuna ukutsala ingqalelo yoluntu kwinqaku leLinux xa usebenza ngee-NVMe SSD ezininzi kwinkqubo enye. Iya kufaneleka ngakumbi kwabo bathanda ukwenza ii-RAID zesoftware ukusuka kwiNVMe.
Ndiyathemba ukuba ulwazi olungezantsi luya kunceda ukukhusela idatha yakho kunye nokuphelisa iimpazamo ezicaphukisayo.
Sonke siqhele le logic ilandelayo yeLinux xa usebenza ngezixhobo zebhlokhi:
Ukuba ifowuni ibizwa ngokuba yi / dev / sda ngoko izahlulo kuyo ziya kuba / dev / sda1, / dev / sda2, njl.
Ukujonga iimpawu ze-SMART, sisebenzisa into efana ne-smartctl -a /dev/sda, kwaye uyifomethe kwaye ungeze izahlulo kuluhlu, njenge /dev/sda1.
Sonke siqhelene ne-axiom yokuba / dev / sda1 ibekwe kwi / dev / sda. Kwaye, ukuba ngenye imini i-SMART ibonisa ukuba / i-dev / i-sda iphantse yafa, ngu / dev / sda1 ukuba siya kulahla ngaphandle kwe-RAID uluhlu lokubuyisela.
Kuyavela ukuba lo mgaqo awusebenzi xa usebenza nge-NVMe Namespaces. Ubungqina:
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 onobuqili wothelekiso lwenombolo yothotho uya kuqaphela ukuba i/dev/nvme1n1 ibekwe kwi/dev/nvme2, kwaye ngokuchaseneyo.
P.S.
Ndinqwenela ukuba ungaze ususe i-NVMe SSD yokugqibela kuluhlu lwe-RAID.
