Mac users who work with multiple platforms may notice that OS X is unable to mount EXT partitions on its own, and thus anyone wishing to mount and read EXT drives and other file systems will need to rely on a third party utility.
Options are dependent on the file system. You may use "defaults" here and some typical options may include: You can find a discussion of relatime here: This relates to when and how often the last access time of the current version of a file is updated, i.
For mounting samba shares you can specify a username and password, or better a credentials file. The credentials file contains should be owned by root. This is really unnecessary as this is the default action of mount -a anyway. You must explicitly mount the filesystem.
This automatically implies noexec, nosuid,nodev unless overridden. This is also a default setting. Equivalent to rw, suid, dev, exec, auto, nouser, async.
Only valid with fstype nfs.
For specific options with specific file systems see: If set to "0" file system ignored, "1" file system is backed up. Dump is seldom used and if in doubt use 0. Pass fsck order Fsck order is to tell fsck what order to check the file systems, if set to "0" file system is ignored.
Often a source of confusion, there are only 3 options: All partitions marked with a "2" are checked in sequence and you do not need to specify an order. Use "0" to disable checking the file system at boot or for network shares.
You may also "tune" or set the frequency of file checks default is every 30 mounts but in general these checks are designed to maintain the integrity of your file system and thus you should strongly consider keeping the default settings.
Examples The contents of the file will look similar to following: These network share examples samba, nfs, and sshfs assume you have already set up the appropriate server. If you do not want to enter a password, use a credentials file. Extended file systems ext Specifically, these are the ext2ext3and ext4 filesystems that are common as root filesystems in Linux.
The main difference between ext2 and ext3 is that ext3 has journaling which helps protect it from errors when the system crashes.
The more modern ext4 supports larger volumes along with other improvements, and is backward compatible with ext3. You can do this on Music and Movies to access these files from Ubuntu. Editing fstab Please, before you edit system files, make a backup. The -B flag with nano will make a backup automatically.
To edit the file in Ubuntu, run:Differences from previous versions. GRUB 2 is a rewrite of GRUB (see History), although it shares many characteristics with the previous version, now known as GRUB barnweddingvt.com of GRUB Legacy may need some guidance to find their way around this new version.
Filesystem in Userspace (FUSE) is a software interface for Unix-like computer operating systems that lets non-privileged users create their own file systems without editing kernel code. This is achieved by running file system code in user space while the FUSE module provides only a . Mar 20, · While OSXFuse adds EXT read support, write support to EXT is disabled by default and probably not recommended to use at all, it’s considered experimental and unsupported by FUSE for a reason.
You need a specific fuse driver for each file system type, as the point of fuse is to have the file system code running in user-land. So any pre-existing kernel driver code, running in kernel-land (ext2, ext3, ext4, xfs) can't be used 'as-is' by fuse.
This refers to the autofs mount point. This can be a single directory name for an indirect mount or the full path of the mount point for direct mounts. Each direct and indirect map entry key (mount-point above) may be followed by a space separated list of offset directories (sub directory names each beginning with a "/") making them what is known as a multi-mount entry.
