Ever since upgrading to Fedora 36, my root filesystem is getting corrupted every few hours. I maintain block level backups, and I have to restore every time this happens. xfs_repair can fix the filesystem, but the system is typically unusable as there's often over 10k files in lost+found. I have tried creating a brand new filesystem (mkfs.xfs), but it still gets corrupted. I would file a bug, but the caveat is that I also have LVM underneath the filesystem. And so I don't know whether it's a problem with XFS, or LVM. I have other XFS filesystems also on LVM, and have seen corruption on them as well, but it's nowhere near as significant or frequent as on the root filesystem. Sometimes I can detect the corruption before the kernel does, by doing a snapshot, and running `xfs_repair -n` on the snapshot. And sometimes the kernel will detect the corruption first, usually with a message like: Jul 17 15:06:52 whistler kernel: XFS (dm-0): Metadata corruption detected at xfs_buf_ioend+0x14c/0x5d0 [xfs], xfs_inode block 0x46057c8 xfs_inode_buf_verify Jul 17 15:06:52 whistler kernel: XFS (dm-0): Unmount and run xfs_repair Jul 17 15:06:52 whistler kernel: XFS (dm-0): First 128 bytes of corrupted metadata buffer: Jul 17 15:06:52 whistler kernel: 00000000: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................

Is there any way to determine whether this is an LVM issue or an XFS issue? _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
