Hi.
I have a raid1 system running in degraded mode.
Now that I have retrieved my 2. disc, I wanted to add it to the raid
(kind of the reason for me to run raid1).
I have tried to run 'raidhotadd' but is complains:
root@gw:~# raidhotadd /dev/md/4 /dev/ide/host0/bus0/target1/lun0/part5
/dev/md/4: can not hot-add disk: too small disk!
I dont know excatly what this error is, but I guess it thinks that the
partition that i try to add is too small, though it has excatly the same
size af the existing one running raid1.
Does the new partrition need to be larger than the existing one? - this
seems very strange....
Below is some relevant info taken from my system btw. I'm using devfs.
Any help would be appriciated.
