   Darn src rpm is “failing” on Fedora12 because it can’t find the lessfs.cfg in /etc. I’m going to try to copying the lessfs.cfg-hamsterdb, but so far I haven’t found the right place. Probably going to have to untar then retar. I’ll post an update.

   Okay, after an rpmbuild –rebuild lessfs-1.3.1-1.src.rpm
   went into SOURCES untarred the tgz, copied lessfs.cfg-hamsterdb to lessfs.cfg and tarred the directory and then did an rpmbuild –bb SPEC/lessfs.spec and build completed.

   rpm -Uvh succeeded. Interesting, there is no hamsterdb dependency.

     Instead of rebuilding your tarball, consider adding a line like this in the %build section of the spec file:

     cp etc/lessfs.cfg-hamsterdb etc/lessfs.cfg

       Also, I built a spec file for hamsterdb tonight, if anyone is interested.

         When I would do a mklessfs and then a service lessfs start, nothing would happen. I haven’t tried making a lessfs.cfg-hamsterdb in /etc.

     I can’t seem to get lessfs to start. I’m going to try testing with 1.2.2.6

   Turning off transactions while hamsterdb is active yields a fatal error:

   start_flush_commit : failed to commit transaction() returned error -8: Invalid parameter

   because txn was never initialized, but you unconditionally call ham_txn_commit() and ham_txn_begin() in commit_transactions() without checking config->transactions first.

   (I’m not clear if this option is even *meant* to work with hamsterdb, though.)

   Good night!!!

   I’m testing lessfs with some mailbox: too much little file so that my little script to get stat from lessfs_stat became very slow…so i tried to make a “little patch” for lib_tc.c just to describe my idea:

   root@dedup:~/lessfs-1.3.1# diff lib_tc.c lib_tc.c.orig
   1299,1301d1298
   < float dedup=0;
   < float orig=0;
   <
   1318,1319d1314
   stbuf.st_size;
   real_size;
   1325,1326d1319
   stbuf.st_size;
   real_size;
   1336,1337d1328
   < lines[count++] = as_sprintf("File Dedup Original Perc\n");
   < lines[count++] = as_sprintf("%i %.0f %.0f %3.2f\n",count,dedup,orig,dedup/orig*100);

   After this mod i add 2 line at bottom of lessfs_stat so we just need to read that 2 line to get some fast summary:

   root@dedup:~/lessfs-1.3.1# tail -2 /dedup/.lessfs/lessfs_stats
   File Dedup Original Perc
   93 59168874496 61916155904 95.56

   Perhaps it should be better to put that info in some other file or produce in some other way i dont know.

   This is just for suggest my idea

   Happy dedup
   Gianni
