Sdx 問題

edenho

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 ?

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.
