Shulou(Shulou.com)06/02 Report--

After using 100% of the / U01 directory in the test environment, it is found that / oradata is basically not used.

Using lvreduce and lvextend to reduce the LV corresponding to / oradata and / U01 respectively, you need to resize the file system after success.

The file system corresponding to / U01 can operate normally.

Resize2fs-p-F / dev/mapper/vg_stb-lv_u01 is fine.

However, it is not allowed for / oradata, and an error has been reported after processing after umount.

Lvremove also failed.

Finally, it is solved by formatting.

Re-mount after mkfs.ext4 / dev/demosysvg/oradata_lv
