VFS: Busy inodes after unmount. (SOLVED)

First thanks in advance for your attention. I have a proxmox that is giving me this error:

Re: VFS: Busy inodes after unmount. (SOLVED)

Well!!

In this case the error is caused by trying to use an external hard drive mount in /mnt ,which had suffered a power failure.

I think this error is not the cause of kernel panic.

Continue to test. ;)
