https://bugzilla.kernel.org/show_bug.cgi?id=199727 --- Comment #6 from Roland Kletzing (devzero@xxxxxx) --- what i have also seen is VM freezes when backup runs in our gitlab vm server, which is apparently related to fsync/fdatasync sync writes. at least for zfs there exists some write starvation issue , as large sync writes may starve small ones, as there apparently is no fair scheduling for it, see https://github.com/openzfs/zfs/issues/10110 -- You may reply to this email to add a comment.
