I ran a memtest over a couple of hours with no errors. Ram seems to be fine so far. I've looked at the link you provided. Frankly it looks very scary. (At least to me it does) But I've just thought of something else. My storage array is BTRFS Raid1 with 4x8TB Drives. Wouldn't it be possible to simply disconnect two of those drives, mount with -o degraded and still have access (even if read-only) to all my data? E.g. I could use the two removed drives as a backup and rebuild my array from there. Since I'm kind of playing with the idea of turning it into a MD RAID5 and only use btrfs on specific lvm volumes which need it. The one thing that slightly worries me with this idea is, I don't know if there is a way to tell which datablocks are on which drives. If I've understood btrfs raid1 correctly it simply ensures that there is at least a copy of each block on a different device. Would my idea work? Or could it be that I can only safely remove one drive, since the other drives might contain blocks from any of the other drives? -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
