[Discuss] Discuss Digest, Vol 100, Issue 4

[Peter Willis]

Hello,

You should back up your important files to a different disk as soon as possible.

Then reinstall your system but only encrypt your important data partitions (ie: not your boot)

Guessing here, but it's mounting the file system read only to users because the file system is not clean.
If your boot patition has a journal and, is not cleanly unmounted before shutdown, the fils system, check will need to find blocks that are accessible to clean up your file system before rebooting with a fixed one.

The journal is used to fix corruption by accounting previous changes made to the file system.

See:  https://pages.cs.wisc.edu/~remzi/OSTEP/file-journaling.pdf

If you have power issues, your disk is borderline, combined with encrypted boot files,  journalling file system,...etc....  
fsck will do what it can, until it can't anymore. It's likely fsck needs a reboot to complete the remount of fstab or mtab in user mode.

Best to put  '/home'    and any other user data specific data paths in thier own partitions and just encrypt the partition.

If you have encrypted budget SSD you can do battle with crappy hardware leveling and then, one sunny day, sudden failure will lose all of your data irrecoverably. Quality mechnical disks are more recoverable. Make backups to an external RAID that includes a 'spare' . That RAID should be high quality mechnical disks. Alternatively, backup to a cloud service if you have a network capable of moving all your changes in a single day.

Make sure you make regular backups if you use SSD. Make doubly sure of regular backups if your SSD is economy brand, and your power supply is economy brand, and your power utility provider is an economy brand.  All that 'economy' becomes moot when your files are gone.
Don't trust    'Smart Drive'  disk status. The only 'Smart Drive'  is a backed up drive.

My opinion.

I was using my laptop running a Debian based operating system with full disk encryption and I started noticing recently that sometimes I would start getting a nonsensical box pop up on screen saying that my hard disk is a “read only” file system and cannot complete some kind of operation or another. Then I would start having issues with not being able download files from the internet or change anything on the hard drive but it would go back to being normal and fine only after reboot. I couldn’t find working solutions online. So this most recent time this happened and I rebooted and entered my passphrase in grub then it proceeded towards the login screen but the system would drop to a black busybox screen just before loading login screen. It seems to be failing to mount the system. I’m not dual-booting with anything though.
