Updating bad block inode

(Or the filesystem superblock is corrupt) The superblock could not be read or does not describe a valid ext2/ext3/ext4 filesystem.If the device is valid and it really contains an ext2/ext3/ext4 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an alternate superblock: e2fsck -b 8193 The superblock contains information about the file system such as the file system type, size, status, information about other metadata structures, block counts, inode counts, supported features, maintenance information, and more and so on (source).If you like this article, consider sponsoring me by trying out a Digital Ocean VPS.

It is an important piece of information for the filesystem.

So the card is so broken that the first superblock is not readable.

One of my Raspberry Pi's would not boot up after a reboot. This article walks you through the steps I took to try to fix the SD card, including fsck, badblocks and other filesystem utilities.

It also has tips to reduce the writing on the Raspberry Pi, this to save SD cards from some amount of wear and thus possible corruption.

I decided to change this to every boot, so problems will be found and possibly fixed earlier.

To set up an fsck at every boot, execute the following command: This lowers the amount of disk space used, the amount of packages updated and the amount of services running on the machine, saving both RAM and disk space. The Raspberry Pi was reinstalled and the software was set up again.

(referral link) The machine was running as an FM transmitter so that my regular sound system could play podcasts (Please note that it is probably illegal to transmit without having your HAM license).

I't would sync up my feeds and, when turned on, started playing them.

The first one is to mount a few folders in RAM as command or reboot the machine to make this active.

Linux divides its physical RAM (random access memory) into chucks of memory called pages.

There was also a good explanation of where the Out of Memory error comes from on Stack Exchange, it might not be out of memory.
