clog盘满了，扩容下
磁盘空间正常的，还剩余400g左右，另外total_size(MB)=512，日志里边这个总大小怎么才512m呢，我用obd cluster config，查看参数如下：
obagent:
servers:
- 127.0.0.1
global:
home_path: /root/obagent
ob_monitor_status: active

cpu_count: 46
datafile_size: 2048M

datafile_next: 2048M
log_disk_size: 14336M
看下这个值多大？ 截图发下
select * from oceanbase.__all_unit_config;
现在数据库都起不了呢，无法查询呢，头疼
明白你意思了，我应该是租户的设置少了，达到限制了，我能否先手工删除日志文件，让服务线启动
先将这个调大些，调整到50G，先启动起来，在查看log_disk_size
obd cluster edit-config 集群名称
扩大再次尝试试下
不能手动清理clog，手动删除clog后集群就彻底无法启动了
df -h 看下磁盘空间
尝试带参启动下
./bin/observer -o “log_disk_size=50G,log_disk_utilization_threshold=95,log_disk_utilization_limit_threshold=98”
注意：如果报错libmariadb.so.3: cannot open shared object file
修复方式：
#将 OceanBase 数据库的 LIB 加到环境变量 LD_LIBRARY_PATH 中，按实际路径替换下面路径即可。
echo ‘export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:~/oceanbase-ce/lib/’ >> ~/.bash_profile
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:~/oceanbase-ce/lib/
这个问题有进展了吗
