Hi, I have a raid1 with 3 drives: 698, 465 and 232 GB. I copied 1,7 GB data to that raid1, balanced the filesystem and then removed the bigger drive (hotplug). The data was still available. Now I copied the /root directory to the raid1. It showed up via ls -l. Then I plugged in the missing hard drive again (hotplug). After a few seconds "btrfs fi show" is giving output as usual: Label: none uuid: 16d5891f-5d52-4b29-8591-588ddf11e73d Total devices 3 FS bytes used 1.60GiB devid 1 size 698.64GiB used 4.03GiB path /dev/sdg devid 2 size 465.76GiB used 4.03GiB path /dev/sdh devid 3 size 232.88GiB used 0.00B path /dev/sdi The /root is still showing up, but the raid1 is now mounted in *read-only* mode. I umounted it and mounted it again. Now the /root directory on the raid1 is no longer available. Its gone. I guess I missed some important step to recover the degraded raid1 before umounting it. What is it that I missed?
