innobackupes fails

Hello dear Percona team,

I faced with two errors using innobackupes:
1.Trying to reproduce on my memory.

missing ib_logfile0trying to createmysql is using that filewait……Something is wrong on source files

Actually these logs were on their place. Not sure why innobackupex didn’t recognize them.

Then that error dissappeared and new error came:

110315 23:36:07 InnoDB: Warning: allocated tablespace 159, old maximum was 0InnoDB: No valid checkpoint found.InnoDB: If this error appears when you are creating an InnoDB database,InnoDB: the problem may be that during an earlier attempt you managedInnoDB: to create the InnoDB data files, but log file creation failed.InnoDB: If that is the case, please refer toInnoDB: Error: ibbackup child process has died at /usr/bin/innobackupex-1.5.1 line 542.

I use CentOS 5.5 64-bit and MySQL 5.5.9
The same command on the same database with similar config is working well on test server, but doesn’t work on production slave.

Thank you in advance,
