Bug ID: 218349
Summary: f2fs partitions corrupted during power failures and
cannot be fixed with fsck.
Product: File System
Version: 2.5
Hardware: AMD
OS: Linux
Status: NEW
Severity: normal
Priority: P3
Component: f2fs
Assignee: filesystem_f...@kernel-bugs.kernel.org
Reporter: qinfd2...@lzu.edu.cn
Regression: No
I am using some Debian VMs with f2fs root partition for development.
My host machine crashed for some reason and this caused the f2fs partitions in
the VMs to become corrupted.
I tried to boot from Debian Live and repair the partitions but failed.
