It happened to me repeatedly on both openSUSE Leap and openSUSE Tumbleweed during the 4 years I worked for SUSE: 2017-2021.

The `df` command doesn't work: it does not give reliable info. That alone disqualifies this FS for me.

The `fsck` equivalent does not work: every time I have tried, it corrupts volumes into unreadability.

Those 2 things are hard requirements for me.

I raised this internally as significant issues. They were dismissed.
