Public bug reported:
Binary package hint: zfs-fuse
Hello to all,
I have 5 disks and when I am creating a raidz vdev I am not getting the
proper capacity:
I think the capacity should be 1500+2000+640+160+150-2000 ~= 2450 GB but
is under 700 GB....
Could you please tell me if this this is normal? What am I doing wrong?
I am also attaching various disk combinations for the zpool which show
that adding disks, the total size is decreasing.... This is really
peculiar I think...
Merry Christmas to everyone!....
