It sounds like it's about once every 2-3 weeks? Would you be willing to experiment running the VM without using the RAID1 so we're bypassing the MD layer? One of the common factors between those people who are reporting this are (a) they are using KVM, and (b) they are using RAID. Now, I'm doing all of my testing using KVM, and I've never seen anything like this. So I wonder if the operative issue is happening at the MD layer.... You workload is common enough that I would expect that if this was happening for everyone who was using ext4, I should be getting a lot more bug reports. -- You are receiving this mail because: You are watching the assignee of the bug.
