xtrabackup 2.1.2 2.1.3 均出現以下問題:
1
2
3
<code>xtrabackup: warning: Log block checksum mismatch (block no 191401143 at lsn 3946288081920):</code>
<code>expected 800836998, calculated checksum 800832263</code>
<code>xtrabackup: warning: this is possible when the log block has not been fully written by the server, will retry later</code>
innobackupex: Error: ibbackup child process has died at /usr/bin/innobackupex line 389.
DBD::mysql::db selectrow_array failed: MySQL server has gone away at /usr/bin/innobackupex line 1325.
然後就是無限期的等待;
現象可以解釋為子程序把 redolog 跟丢啦,線上的redo log 大小均設定為 1G;
官方的回複是:更新版本,将redo log 調大;在業務低峰的時候進行備份;
目前隻能把版本更新至2.1.6;
各位你們是否碰到過類似問題?
