I see I''m not the only one to flounder with this. Btrfs v0.19 on openSuSE 11.3-RC1 (2.6.34-9-default). I created a RAID10 across 4 partitions - worked fine. Unmounted it and zeroed one complete partition (as in of=/dev/sda8). Remounted degraded, looked around, data seemed safe. Attempted to remove sda8 from the array, but got an ioctl=1. Hmmm. Did a (normal, non-RAID) mkfs on the partition, then attempted to add it back as per the wiki. Won''t mount without the degraded option even though the 4 partitions are accepted o.k, and a re-balance worked. The array now reports as 5 devices with #2 (the original slot for sda8) now vacant - dare I say "missing". It reports as "*** Some devices missng" This seems counter intuitive to me. Suggestions ?. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
