Ubuntu

找出自動掛載設備的類型

  • June 8, 2012

我正在開發一個系統(Ubuntu Precise),其安裝定義/etc/fstab如下:

/dev/vdb        /mnt    auto    defaults,nobootwait,comment=cloudconfig 0       2

最初我只是想知道它是否是 NFS(由於潛在的 MySQL 鎖定問題)。從 判斷man mount,不是:

If no -t option is given, or if the auto type is specified, mount will try to guess the desired type.  Mount uses the blkid library for guessing  the
filesystem type; if that does not turn up anything that looks familiar, mount will try to read the file /etc/filesystems, or, if that does not exist,
/proc/filesystems.  All of the filesystem types listed there will be tried, except for those that are labeled "nodev" (e.g., devpts, proc  and  nfs).
If /etc/filesystems ends in a line with a single * only, mount will read /proc/filesystems afterwards.

但是,現在出於好奇,我怎樣才能更多地了解它實際上是什麼類型的設備?(對於上下文,這是在 OpenStack 上執行的 VM。該設備是從某個地方安裝的 60Gb 分配 - 但我不知道如何。)`

編輯包括這裡的答案:

$ mount
/dev/vdb on /mnt type ext3 (rw,_netdev)

$ df -T
/dev/vdb                       ext3        61927420     2936068   55845624   5% /mnt

你會滿意df -T /mnt嗎?:)
