用xtrabackup2.4备份mysql5.6.30一直显示log scanned up to
一直处于log scanned up to,只能ctrl+c强制终止备份
没有大事务
停止xtrabackup前
停止xtrabackup后
没事大事务,大概用了15分钟
xtrabackup: Transaction log of lsn (104012539342) to (104012560503) was copied.
170420 17:31:43 completed OK!
real 15m18.319s
user 12m48.151s
sys 0m11.271s
因为用了gzip压缩,机器配置比较低导致gzip的cpu使用率是96%
一般170420 17:04:16 >> log scanned up to (441263433482)
后面的这个数字441263433482有变化就不用担心,如果后面这个数字没有变化,表示xtrabackup进程被hang住了,可能有大事务需要注意
