Nthawi yabwino ya tsiku.
Ndinkafuna kukopa chidwi cha anthu ammudzi ku mawonekedwe a Linux mukamagwira ntchito ndi ma NVMe SSD angapo mudongosolo limodzi. Zidzakhala zofunikira makamaka kwa iwo omwe amakonda kupanga mapulogalamu a RAID kuchokera ku NVMe.
Ndikukhulupirira kuti zomwe zili pansipa zikuthandizani kuteteza deta yanu ndikuchotsa zolakwika zosautsa.
Tonse timazolowera malingaliro otsatirawa a Linux tikamagwira ntchito ndi zida za block:
Ngati chipangizocho chimatchedwa / dev / sda ndiye magawo omwe ali pamenepo adzakhala / dev / sda1, / dev / sda2, etc.
Kuti muwone mawonekedwe a SMART, timagwiritsa ntchito ngati smartctl -a /dev/sda, ndikuisintha ndikuwonjezera magawo pazotsatira, monga /dev/sda1.
Tonse tinazolowera axiom kuti /dev/sda1 ili pa/dev/sda. Ndipo, ngati tsiku lina SMART iwonetsa kuti / dev / sda yatsala pang'ono kufa, ndi / dev / sda1 kuti tidzataya kuchokera ku gulu la RAID kuti tilowe m'malo.
Zikuoneka kuti lamuloli siligwira ntchito mukamagwira ntchito ndi NVMe Namespaces. Umboni:
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
Wowerenga mwanzeru pakuyerekeza kwa nambala ya serial adzazindikira kuti /dev/nvme1n1 ili pa/dev/nvme2, ndi mosemphanitsa.
P.S.
Ndikukhumba kuti musachotse NVMe SSD yomaliza pagulu la RAID.
