Fix EXT4-fs error loading journal

If occurs an  EXT4 filesystem error to loading journal, use the e2fsck to solve an inodes problems.

e2fsck is used to check the ext2/ext3/ext4 family of file systems. For ext3 and ext4 filesystems that use a journal, if the system has been shut down uncleanly without any errors, normally, after replaying the committed transactions in the journal, the file system should be marked as clean. Hence, for filesystems that use journalling, e2fsck will normally replay the journal and exit, unless its superblock indicates that further checking is required.

change X for the number os partition (i.e. /dev/sda2)

# e2fsck -C0 -p -f -v /dev/sdaX

used options:

-C fd


This option causes e2fsck to write completion information to the specified file descriptor so that the progress of the filesystem check can be monitored. This option is typically used by programs which are running e2fsck. If the file descriptor number is negative, then absolute value of the file descriptor will be used, and the progress information will be suppressed initially. It can later be enabled by sending the e2fsck process a SIGUSR1 signal. If the file descriptor specified is 0, e2fsck will print a completion bar as it goes about its business. This requires that e2fsck is running on a video console or terminal.

-p


Automatically repair ("preen") the file system. This option will cause e2fsck to automatically fix any filesystem problems that can be safely fixed without human intervention. If e2fsck discovers a problem which may require the system administrator to take additional corrective action, e2fsck will print a description of the problem and then exit with the value 4 logically or'ed into the exit code. (See the EXIT CODE section.) This option is normally used by the system's boot scripts. It may not be specified at the same time as the -n or -y options.

-f


Force checking even if the file system seems clean.

-v


Verbose mode.

Install Matlab in Slackware 14.2

In Terminal:

Requisits: JDK installed

$ sudo mkdir -p /usr/local/MATLAB/R2016a

$ sudo chmod a+w -R /usr/local/MATLAB/

In the DVD of Matlab:

$ ./install

After this, if you want to create the entry in the system's menu, follow this tutorial.

Icon of the Matlab in Slackware

For create the icons after matlab installed:

# cd /usr/local/bin/

# ln -s /usr/local/MATLAB/R2016a/bin/matlab matlab

Create in the system's menu the Matlab item and, in the Command item, put:


matlab -desktop -nosplash

-desktop is a flag needed to run Matlab without a terminal.

-nosplash is a flag preventing the splash screen from showing and taking up a temporary space in your task bar.

To download the icon:


$ curl https://upload.wikimedia.org/wikipedia/commons/2/21/Matlab_Logo.png -o /usr/share/icons/matlab.png
