记录一次inodes用光的情况

this is the xfs_info out_put:

[root@localhost home]# xfs_info /home
meta-data=/dev/mapper/centos-home isize=256    agcount=4, agsize=28938752 blks

/home/www $ du --inodes| sort -n

a few minutes later. someone delete the prometheus directory. and the count of inodes increased automatically.

but the space of /home is still out of usage.

a few minutes later again. the space is back. and I don’t know why.
