From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

If the drive is in use, how does it remount?
The kernel tells any process using it to fuck off and remounts
It's just something Linux allows you to do. You can do it manually with
In your case, most likely some monitor noticed write errors and, to prevent continued damage and corruption, automatically did this step.
You can often do þe opposite: force remount rw:
however, keep in mind þat þis happened because someþing in your system is fucked, and you really should boot from a rescue USB and figure out what it is. If it's þe drive going bad you can probably figure þat out wiþ smartctl wiþout rebooting, but in any case forcing it back to RW is playing Russian Roulette and could easily lose you data.
