1.故障描述
今天ODOO服务器无法正常工作，提示信息如下：
错误:

psycopg2.OperationalError: 错误: 无法写入文件 "base/pgsql_tmp/pgsql_tmp19303.0": 设备上没有空间2.问题排查
上面提示设备上没有空间，无法写入，于是远程登录ODOO服务器进行处理。

先用find查找大于100M的文件

[root@myprod odoo]# du -h mybackup
41G mybackup
[root@myprod odoo]# cd mybackup/
发现占41G的空间。突然记起，当初写自动化备份脚本的时候，忘记了定期删除功能，从1月份到6月份，数据库备份文件已到41GB。
3.问题处理
发现问题后，及时删除备份目录下过时的文件，只留下最近7天数据库备份内容。
[root@myprod mybackup]# rm -rf myodoo_20210{1..5}*[root@myprod mybackup]
# ll
[root@myprod mybackup]# rm -rf myodoo_202105{01..20}*[root@myprod mybackup]

[root@myprod mybackup]
#
删除后，也可以用du查看一下：
[root@myprod odoo]# du -sh mybackup/
4.0G mybackup/
[root@myprod odoo]# df -Th

[root@myprod odoo]#
清理后，已用空间由100%变为25%，再次登录服务器，问题消失。
4.Linux中{}的使用补充
{1,3,5} == 1 3 5
{1..5} == 1 2 3 4 5
{a..e} == a b c d e
{A..z}
{1..50..2}
{1..50..3}
{1..50..4}
{1..50..5}
组合用法
file{1..5} == file1 file2 file3 file4 file5
file{1..2}.{txt,log} == file1.txt file1.log file2.txt file2.log原创声明：本文系作者授权腾讯云开发者社区发表，未经许可，不得转载。
