There is something very wrong here. While mount.s3ql is running, there
will always be a directory ending in -cache in the cache directory. This
directory is only removed after mount.s3ql exits, so if you reboot the
computer, it *must* still be there.
Can you confirm that the directory exists while mount.s3ql is running?
What happens if, instead of rebooting, you just kill -9 the mount.s3ql
process? Does the -cache directory exist? Does fsck.s3ql work in that case?
Best,
