I have a RAID1 raid configured as md0. This device is currently the sole device added to a vg.
One of the disks somehow got removed from md0. I am trying to just add it back. It is nota bad drive.
I used sgdisk to clone the partition map and reset the UUID. I have even check that the part ion that I am trying to add (sdh1) is exactly the same size as the one (sdg1) that is still part of the md.
However, when I issue
mdadm /dev/md0 -a /dev/sdh1
I get the error
mdadm: /dev/sdh1 not large enough to join array
I'm running RH5 with the following kernel
2.6.18-92.1.13.el5 #1 SMP Thu Sep 4 03:51:21 EDT 2008 x86_64 x86_64 x86_64 GNU/Linux
Any advice is appreciated
