网站适配怎么做怎么在百度上做推广

问题现象

对象存储存储桶无法删除，检查发现生命周期过期后存储桶中有文件残留，未完全删除，但实际访问文件时为404，通过s3cmd无法删除对象，且无报错。

问题定位

检查bucket当前状态，发现桶内有大量object残留：

拉取残余文件列表，首先获取pool、bucket id和num_shards：

# 获取pool，ningbo1-zone1.rgw.buckets.index
rados lspools | grep "rgw.buckets.index"
# 获取bucket id，a3c7aedc-fcd5-47f3-8540-887817ea45b0.53713368.242
radosgw-admin bucket stats --bucket {bucket name} | egrep "id"
# 获取shard数量，128
radosgw-admin metadata get bucket.instance:{bucket name}:{bucket id} | grep num_shards

然后拉取文件列表：

for i in {0..127}
dorados -p ningbo1-zone1.rgw.buckets.index listomapkeys .dir.a3c7aedc-fcd5-47f3-8540-887817ea45b0.53713368.242.$i >> objects.txt
done

检查object状态，发现相应数据底层均已删除：

for object in `cat objects.txt`
doradosgw-admin object stat --bucket=xxx --object=$object
done

均报错ERROR: failed to stat object, returned error: (2) No such file or directory。
列出bucket索引，发现所有索引"exists": "true"，判断为索引残留问题，及索引存在但数据已删除。

问题处置

可通过rados rmomapkey删除无效索引：

for i in {0..127}
dofor object in `rados -p ningbo1-zone1.rgw.buckets.index listomapkeys .dir.a3c7aedc-fcd5-47f3-8540-887817ea45b0.53713368.242.$i`dorados -c /etc/ceph/ceph.conf -p ningbo1-zone1.rgw.buckets.index rmomapkey .dir.a3c7aedc-fcd5-47f3-8540-887817ea45b0.53713368.242.$i $objectdone
done

重新扫描修复桶状态（可多次执行）：

# radosgw-admin bucket check --fix --check-objects --bucket=xxx
[]
{}
{"existing_header": {"usage": {}},"calculated_header": {"usage": {}}
}

再次检查，发现桶已正常清空：

# radosgw-admin bucket stats --bucket=xxx
