[Lessfs-users] lessfs crashing with SIGABORT

[David N. <do...@ma...>]

I am running lessfs for the first time.

Attached is the cfg file the log file and a gdb analysis of the events
leading up to the SIGABORT (in gdb a SIGUSER1 is generated instead, I'm
not sure why. Maybe the SIGABOUT comes afterwards).

# equery l -p lessfs
 * Searching for lessfs ...
[-P-] [  ] sys-fs/lessfs-1.5.13:0
[IP-] [  ] sys-fs/lessfs-1.7.0:0
# lessfs --version
-------------------------------------------------------
lessfs 1.7.0

Usage: lessfs [/path_to_config.cfg] [mount_point] <FUSE OPTIONS>

Example :
mklessfs /etc/lessfs.cfg
lessfs   /etc/lessfs.cfg /mnt

A high performance example with big_writes.
(Requires kernel 2.6.26 or higher and a recent version of fuse.)
lessfs /etc/lessfs.cfg /fuse -o use_ino,readdir_ino,default_permissions,\
       allow_other,big_writes,max_read=131072,max_write=131072

I realize that I'm using a larger hash value then is the max according to
the manual (I tried changing this to the maximum value without result).
The sha512sum uses 512 bits and there is not way around that so I
am assuming that the docs are out of date with respect to that, if not
please tell me.

Thanks,
David
