When down-converting a RAID1 LV, if the user specifies too few devices, they will get a confusing message. Ex: [root]# lvcreate -m 2 --type raid1 -n raid -L 500M taft Logical volume "raid" created [root]# lvconvert -m 0 taft/raid /dev/sdd1 Unable to extract enough images to satisfy request Failed to extract images from taft/raid This patch makes the error message a bit clearer by telling the user the count they are trying to remove and the number of devices they supplied. [root@bp-01 lvm2]# lvcreate --type raid1 -m 3 -L 200M -n lv vg Logical volume "lv" created [root@bp-01 lvm2]# lvconvert -m -3 vg/lv /dev/sdb1 Unable to remove 3 images: Only 1 device given. Failed to extract images from vg/lv [root@bp-01 lvm2]# lvconvert -m -3 vg/lv /dev/sd[bc]1 Unable to remove 3 images: Only 2 devices given. Failed to extract images from vg/lv [root@bp-01 lvm2]# lvconvert -m -3 vg/lv /dev/sd[bcd]1 [root@bp-01 lvm2]# lvs -a -o name,attr,devices vg LV Attr Devices lv -wi-a----- /dev/sde1(1) This patch doesn't work in all cases. The user can specify the right number of devices, but not a sufficient amount of devices from the LV. This will produce the old error message: [root@bp-01 lvm2]# lvconvert -m -3 vg/lv /dev/sd[bcf]1 Unable to extract enough images to satisfy request Failed to extract images from vg/lv However, I think this error message is sufficient for this case.
