Package: gocryptfs
Version: 1.6.1-1+b20
Severity: critical
Justification: causes serious data loss
Dear Maintainer,
I'm using a gocryptfs container. Both the save location and mount point are on
partitions other then "/" that where not full. Whilst installing packages with
apt the root file system got overfilled. After fixing that situation by
deleting log files and rebooting (reboot was necessary as for unknown reasons
the root file system still reported to be full) I noticed that the content of
some of the directories in the mounted gocryptfs were empty.
Running gocryptfs -fsck (...) gave:
Using config file at custom location (...)

fsck summary: 10 corrupt files
Looking into the encrypted directory after that showed that the encrypted data
was missing. This wasn't verified before running "gocryptfs -fsck".
Interestingly the directories that lost their content are alphabetically last
if sorted by encrypted directory name.
Both filesystems, the root filesystem and the filesystem that hosts the
gocryptfs ecrypted directory are ext4.
I can not be sure that this is caused by gocryptfs and not by some underlying
filesystem problem, but I think it warents checking if gocryptfs can be
dammaged by a filled root file system. For example by not being able to use
/tmp?
Best
Matthias

Following the closure of this issue upstream [1] I am closing this bug
also. Please reopen if a causal relationship appears likely again.
Thanks!
