I have a dataset that consistently cannot be backedup+restored with xtrabackup.
Backup with XtraBackup on master server works; prepare-log works. But when starting meant-to-be slave, it immediately crashes with signal 6, infinitely.
This happens to me on this dataset for several MySQL versions and several XtraBackup versions. Namely, last time:
MySQL is: Percona XtraDB 1.0.8-11.2 (MySQL version 5.1.47-log) - 64bit linux, identical on both machines
OS is Ubuntu Server 10.04 Lucid (64bit)
Tables are in Barracuda, COMPRESSED format (KEY_BLOCK_SIZE=8 for all)
Attached error log; see infinite crash message.
XtraBackup is 1.6-245.lucid, identical on both machines
