@阳光爱上彩虹：请把执行gcrcman.py ... -e"show backup"的结果发一下
阳光爱上彩虹发表于 1年前
@小白591：不好意思啊，有问题的备份集找不到了，因为我这边也在测试修改，导致刚刚一直在还原当时的代码复现这个问题。下图最新的备份集信息，用这个备份集恢复时报错和之前发的两个日志一样，所以可以认定是同一个问题

@阳光爱上彩虹：从报错信息看，192.168.35.58这个节点在执行recover操作的时候报了unknow error，192.168.35.61和60两个节点可以正常执行，需要排查192.168.35.58节点备份目录下的数据是否完整，包括备份目录的权限等信息。
可以直接在58节点上执行：
/opt/gbase/192.168.35.58/gnode/server/bin/rcman -g -T 20110531000000 -Ugbase -t192.168.35.58 -pXXXXXXX -r 4 -c -C -d "/usr/local/csdu/working/dc_mnt/c7b0b4dcad794421862812740a7fa591/vc1.bigdb/GclusterData_coordinator1_node1/BackupCycle_0/gnode" -e "recover database bigdb 0 0"
看手动执行时会输出怎样的报错

忽略，是我之前恢复失败的库没有删除导致的

@小白591：问题定位到了，我把权限改成777就能成功恢复。您这边暂时不用定位，辛苦您了

杏花开了燕飞忙，正是好春光。偏是好春光，者几日、风凄雨凉。杨枝飘泊，桃根娇小，独自个思量。刚待不思量，吹一片、箫声过墙。
