IBM Spectrum Protect Snapshot restore operations on Linux may
fail with error FMM1040E indicating a
VolumeManagerLogicalVolumeError because one file system that
should be restored could not be unmounted. The IBM Spectrum
Protect Snapshot does not detect that the file system is busy
and could not be unmounted but instead continues with the
restore processing and tries to remove the corresponding logical
volume which then fails.
If multiple file systems should be restored and some of them
could be unmounted successfully, this may result in some logical
volumes of those unmounted file systems also being removed.
Another logical volume in this case could not be removed and
caused the described error message.
