Re: BTRFS with 8TB SMR drives

Yes, correct its drive managed SMR. I have been following this bug: https://bugzilla.kernel.org/show_bug.cgi?id=93581 for a while As a test I compiled/installed 4.3.0-rc4 as it looks like they reverted some kernel patches that (negatively) affect SMR. I ran a complete balance overnight and not

BTRFS with 8TB SMR drives

Hi guys, just added a new Seagate Archive 8TB drive to my BTRFS volume and I'm getting a tonne of errors when balancing or scrubbing. A short smartctl test reports fine, running a long one now. Will also run seatools from a bootable DOS USB while at work today. Running latest firmware on my

Re: BTRFS with 8TB SMR drives

Re: BTRFS with 8TB SMR drives

Is it possible to get a complete dmesg included in the thread, or if it's too big attach it to a bug report? I'm curious if there are any libata messages, as well as the specific Btrfs messages. --- Chris Murphy -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the
