Hi, Few days ago my XFS filesystem broke. I have two kernels on my system - 3.10 installed from default repo and 4.18 installed from "elrepo". 4.18 was active, but when I ran 'yum update', new 3.10 was installed, was automatically set as default and was active after the reboot. Not so long after, XFS broke. dmesg output: [683670.924618] XFS (sdc): Internal error XFS_WANT_CORRUPTED_RETURN at line 212 of file fs/xfs/libxfs/xfs_dir2_data.c.

Is this kernel mixup the reason for it? How do I avoid it? I want to use elrepo as primary. If kernel mixup isn't the reason, does this log says what it was? :) Thanks!
