我部電腦有 msata ssd 同兩隻sata HD, 原先 msata 裝 OS 係 SDA, 但係 reboot 完之後 隻 msata 會轉左做 SDB, 有冇師兄知可以點攪到佢唔會轉

/dev/sdX 只是自動配給一個device嘅識別代號,
固定安裝在電腦的HDD, 那在fstab那裡設置妥, 而fstab那裡用LABEL或UUID去指定某一個device做掛接會更可靠.
除非是不常mount的外置碟, 才會每次打指令去掛接, 但那槪然不常用, 要mount時, 先打個blkid看看也不會很困難吧.

我就係乜都冇做過，所有碟都係內置，想知有乜方法可以 lock 隻，新手勿怪

所有碟都是內置的話, 就更應在/etc/fstab那裡一次過寫好所有碟的掛接點, 以後著機便會自動掛接妥當, 而fstab裡不要用/dev/sdx而盡量用LABEL或用UUID來區分不同HDD..

樓主個/etc/fstab可以睇睇嗎？

your fstab seems ok, why you want your sda bind to a particular disk ?
作者: SAGAQWE 時間: 2021-1-25 16:24
linux真喺好， less個fstab內容， 一開頭幾句就教咗你啦。。

我係想知點解每次boot 都有機會唔同和亂左
同每次一亂 個 OMV 一開個 file system page 就會瓜左，ssh 同 ping 都見唔到隻野，要 local reboot 一次先得順返哂就正常。

if you are using raid, a disk may have two UUIDs, one for physical disk, one for raid config.

明明係 fstab 睇隻 os disk mount 係 SDA, 但係個 OMV 睇又變左做 SDE

可以改udev rule令佢 sd* 固定嘅
但係無咩可能會連ssh 都連唔到架喎
應該有其它問題
local console 仲 login 到嗎?
fstab 己經係用uuid 啦
"#" 開頭嘅注釋係無影響架

佢出乜字母係關bios事, 唔關fstab事
fstab只係幫你mount去指定目錄
#開頭果D只係comment, 寫乜都唔影響效果
好習慣應該忘記/dev/sdx呢個諗法, 全部用哂UUID黎做野
因為/dev/sdx會成日變, UUID係唔會變 (除非你format)
