Workaround lingering dirty bit on Mk.7 USBMS partition - Page 2

geek1011 · 06-07-2020, 06:23 PM

I just ran into a serious issue with this bug in Nickel (without this mod) on my Clara. The config file was corrupted when it was connected.

Update: This just got worse for me. I think I'll do a factory reset, then modify the Kobo scripts to do a non-lazy unmount.

An integrity check on the db:

Code:

Error: database disk image is malformed
sqlite> .recover
---db dump removed for brevity, but of interest is some rows which have disappeared since my last backup, and a few missing indices---

Some messages from dmesg on my laptop:

Code:

[83950.045837] VFS: busy inodes on changed media or resized disk sdd

There's nothing useful in the dmesg files left in the .kobo directory (and the recent ones were corrupted, then removed by the firmware [why, kobo :/] after they were recovered by fsck).

Ugh. I think my USB controller in my computer is failing (or it might be loose, but I don't think my cable is bad) too (the SD card in the Kobo is fine). I'm going to switch back to my laptop and try the sqlite recovery again. Note that the FS was working fine before (plus, I've been accessing my Kobo from my laptop until this time anyways), and I did that integrity check over telnet on the Kobo itself.
