Public bug reported:
I am experiencing filesystem corruption with ecryptfs on my /home
partition, which is separate from /.
I am attempting to back up important stuff, but struggling to do so (it
is incredibly slow and 100% cpu usage on both cores)
In general, the following errors are occurring:
- Random disk IO errors (mostly during writing)
- Very slow access times for files on the file system. In most cases, files
seem intact, which is good...
- 100% cpu on one or both cores from various programs: rsyslogd, dd are the
most common offenders.
- Programs such as firefox and chrome, when quitting, do not exit, but
persist, and IO on the CPU is continuous from this point onwards (there is no
way to stop this IO usage but reboot)
- dmesg shows hundreds of thousands of ecryptfs errors (see attached file)
I will be reinstalling soon (and am thankful I noticed this before it
caused a major problem), but I am aware that this may be a problem
affecting more than me...
