"Disappearing" filesystems

Hey there -

Dual-boot Lenovo type 20EV (business notebook with zero pizazz but a great keyboard) and Windows 10/Leap 15.1 (all partitions ext4) checking in with a weird one:

I didn’t go with btrfs because I’m not a masochist and (last I knew) ext2/3/4 just work, but now I’m beginning to wonder if I should swallow my ethics and go with ReiserFS?

When using the system - or sometimes when it is idle - ALL the files will just “go away.” If some process is running under X and tries to use the disk, I might get a last-gasp message that an operation could not be completed because the filesystem is read-only, then nothing.

If perchance a terminal is open, I get to see first hand such nuggets as:

  • if I type ls, I get “bash: /usr/bin/ls: No such file or directory”
  • if I type “echo *”, I get an * (I don’t like that AT ALL)
  • if I cd to a real directory, it cds and pwd works as expected
  • if I try to cd to a protected directory such as /root, it refuses
  • if I try to cd to a non-existent directory, it fails
  • “echo ‘blah’ > file” fails read only

No command/file is “there,” but the directory structure appears to be intact; however, “echo *” should show at least any subdirectories present wherever I am in the filesystem.

Nothing useful in /var/log; here’s a snippet of a borked messages, showing that things went south lickety split:

The long string of nulls is where things died; the file resumes following a restart; the successful whining about resolv.conf just before the bazillion ^@s implies that /var still worked for an instant after / went 'bye 'bye. However, /etc/resolv.conf points to a file under /var. so it must’ve failed to find the link while the file was still “there.”

This might happen a few seconds or a few hours into a session; it pretty much always happens. There’s no correlation I can find between what I’m doing and the crashes; CPU usage, a particular operation or what have you.

Windows 10 is as stable as reliable as an anvil, so I do nit suspect a hardware problem.

Help?

Changing to ReiserFS is unlikely to solve your problem.

In my experience, when there is a hardware related fault the file system gets remounted as read-only. That might be what is happening.

Perhaps your disk is spinning down after being idle for a while, and is giving errors when attempting to spin up again. (I’m just guessing there).

Nrickert is right that you are describing symptoms of a root filesystem that is readonly. Your 4.12.14-lp151.28.25 isn’t the newest kernel. Maybe updating would help.

Looking through the kernel messages with »dmesg« or »journalctl« (which also incorporates kernel messages) could be worthwhile here. For a list of suspicious lines, here’s what I like to do:

(One of my whimsical side-hobbies around Linux includes making it boot as quick as possible with as little potential for problems as possible; maybe this helps closing in on the problem you have, mayor_snorkum, be it hardware- or software-related.)

Joking about ReiserFS; SSD, so no spin-down.

Will leave an exerciser running for a couple days, though.

Does your system settle down?
