For some virtual filesystems (like procfs) the value of this field is "none". To mount a hard-drive, the user would list the device path (like /dev/sdb3). For example, to mount tmpfs, the value of this field would be "tmpfs".

The specification may be a path or protocol. This file uses the following format template.ĭevice-specification mountpoint fs-type options/parameters dump pass Both real and virtual filesystems are listed (like the swap space). On many Unix systems, the /etc/fstab file (commonly called the "Filesystem Table") lists filesystems that will be mounted on boot-up. Then, when viewing the contents of /mnt/card/, the user will only see the files that are on the memory card. For instance, to mount a flash-drive under /mnt/card/, the directory "card" must not contain any files. Unmounting is the opposite process where a filesystem is "disconnected" from the filesystem tree.Īnytime a storage unit is mounted, it must be mounted in an empty directory. Then, the removable storage unit is part of the filesystem tree. For instance, on most Unixoid systems, flash-drives are mounted under a directory in /media/ or /mnt/. Mounting is the process of linking a filesystem to the whole filesystem tree. Understanding the filesystem table (/etc/fstab) is an important part in having more knowledge in mounting filesystems.
FSTAB DEFAULTS HOW TO
It may help admins and causal users alike to know how to mount the various filesystems and how to setup the mount to occur automatically. Every filesystem has a slightly different way of being mounted.

This will attempt to mount all ( -a) drives in /etc/fstab and give a verbose ( -v) report.On Linux, filesystems are mounted either manually or automatically.

Please verify that your HDD is formatted as ext4 before trying this otherwise replace ext4 with the format used. If you'll try this entry in /etc/fstab, I hope it will work. They are fine as is, but 0 is the default for both so they aren't actually needed in your case. You do not need the noatime option as that is typically used only on devices such as SD cards which have a "wearout mechanism"įinally, the two 0 (zero) values at the end of your /etc/fstab entry are the fifth and sixth fields. Note that man fstab says do not report errors, but actually it halts the boot process on failure (last I checked anyway). Nofail: don't stop the boot process if this filesystem cannot be mounted. User: allow a user to mount the filesystem - which would include user pi (typically the same as uid=1000,gid=1000, but not necessarily) Rw: allow read and write on the mounted filesystem My recommendation for your 4th field ( fs_mntops) entries is as follows: rw,user,nofail Perhaps you intended that your 3rd field entry auto was to be included here? It would have been a valid entry. Moving on to your 4th field entries ( fs_mntops), you have the option string:
FSTAB DEFAULTS MANUAL
The system manual man mount has additional details on the options. For example: ext4, ext3, vfat, exfat, ntfs, etc, etc. You should use instead the name of the file system used for formatting the drive/partition being mounted. AFAIK, auto is not a proper entry for the type of file system. It appears you have put the term auto in the third field. man fstab tells us that there should be an entry in this field. One of the problems I saw in your fstab entry was that the third field (fs_vfstype) is missing. I've always found the fstab incantations a bit arcane, and man fstab at least does a reasonable job of showing the syntax.
FSTAB DEFAULTS SOFTWARE
Even though it's a bit dated now (Feb 2015), and has at least one error (re behaviour of nofail), it does reflect the software on your system. One step you may have overlooked was checking man fstab - in other words, the system manual for creating & maintaining /etc/fstab.
