I am trying to replacing 1 TB drives with 2TB i am using RAID 1 mdadm
i successfully replaced the first drive and it is synced and working normally.
i also installed grub by this commad "grub-install /dev/sdc"
/dev/sdc is my new drive.
Please note that i am using gdisk to create GPT partition on new 2TB drive.
i copied the same partition table from MBR to GPT with gdisk utility.
however when i try to boot my system only with /dev/sdc
it end up saying
GRUB loading.
Welcome to GRUB!
error: no such device: 2
Entering rescue mode...
grub rescue>
when i connect the first drive i mean 1TB drive with array of 2TB it works fine
when i boot single 1TB it works fine. however when i boot with 2TB alone it shows the above error. i am very new to this i request you guys to please help.
moreover when i use command "ls"
it shows me (hda0)
Thanks,
MYK
