https://bugzilla.kernel.org/show_bug.cgi?id=60644 --- Comment #16 from liveaxle@xxxxxxxx --- Hello . The thing is that I'm using SATA drives and not SAS drives . The motherboard exposes the LSI controller as 8 SATA ports . This wasn't an issue under Windows 2012 , so I think that hardware issues are pretty much not the cause in here . Sorry if I'm demanding too much , but can you try to create a BTRFS RAID1 , fill it with data and then run : btrfs scrub start /MOUNTPOINT It always produces the issue in less than 2 minutes . Thank you . -- You are receiving this mail because: You are watching the assignee of the bug. -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
