首先

root@lyhcc:~# df -hi
    Filesystem     Inodes IUsed IFree IUse% Mounted on
    udev             466K   398  466K    1% /dev
    tmpfs            471K   962  470K    1% /run
    /dev/vda1        2.5M  2.5M     0  100% /
    tmpfs            471K     2  471K    1% /dev/shm
    tmpfs            471K     3  471K    1% /run/lock
    tmpfs            471K    16  471K    1% /sys/fs/cgroup
    tmpfs            471K     4  471K    1% /run/user/0

看到磁盘 /dev/vda1 占用满了

root@lyhcc:~# df -i
    Filesystem      Inodes   IUsed  IFree IUse% Mounted on
    udev            476845     398 476447    1% /dev
    tmpfs           481814     962 480852    1% /run
    /dev/vda1      2621440 2621440      0  100% /
    tmpfs           481814       2 481812    1% /dev/shm
    tmpfs           481814       3 481811    1% /run/lock
    tmpfs           481814      16 481798    1% /sys/fs/cgroup
    tmpfs           481814       4 481810    1% /run/user/0

看到inode满了，其实就是碎片log太多了

root@lyhcc:/# du -sh *

    52K	bbb.pdf

    102M	boot

看到 /data的文件太多了

其实是这样

/data/applogs/xxl-job/jobhandler

xxljob的日志太多了

root@lyhcc:/data/applogs/xxl-job/jobhandler# rm -rf 2021-05-30/
    root@lyhcc:/data/applogs/xxl-job/jobhandler# rm -rf 2021-05-31/
    root@lyhcc:/data/applogs/xxl-job/jobhandler# rm -rf 2021-06-0*/
    root@lyhcc:/data/applogs/xxl-job/jobhandler# rm -rf 2021-06-10/
    root@lyhcc:/data/applogs/xxl-job/jobhandler# rm -rf 2021-06-11/
    root@lyhcc:/data/applogs/xxl-job/jobhandler# rm -rf 2021-06-12/
    root@lyhcc:/data/applogs/xxl-job/jobhandler# rm -rf 2021-06-13/
    root@lyhcc:/data/applogs/xxl-job/jobhandler# rm -rf 2021-06-14/

删除了xxljob的日志后

root@lyhcc:/opt/score/logs# df -i
    Filesystem      Inodes  IUsed   IFree IUse% Mounted on
    udev            476845    398  476447    1% /dev
    tmpfs           481814    962  480852    1% /run
    /dev/vda1      2621440 123087 2498353    5% /
    tmpfs           481814      2  481812    1% /dev/shm
    tmpfs           481814      3  481811    1% /run/lock
    tmpfs           481814     16  481798    1% /sys/fs/cgroup
    tmpfs           481814      4  481810    1% /run/user/0

空间释放了，ok了，可以重新启动你的服务了
