Hi Sergei, Still having this problem with my PXDBC installation of 5.5.41-25.11-853 using Percona Xtrabackup v2.2.11-1.wheezy, but it seems that all xtrabackup/innobackupex part is doing well : innobackup.move.log and innobackup.prepare.log are both reporting : 150630 08:55:16 innobackupex: completed OK! But after all this process, mysql is crashing at start : 150630 8:55:17 [Note] WSREP: SST complete, seqno: 20200769 150630 8:55:17 [Warning] Using unique option prefix myisam_recover instead of myisam-recover-options is deprecated and will be removed in a future release.

It is also possible that this binary or one of the libraries it was linked against is corrupt, improperly built, or misconfigured. This error can also be caused by malfunctioning hardware. We will try our best to scrape up some info that will hopefully help diagnose the problem, but since we have already crashed, something is definitely wrong and this may fail.
