Dear All,
I have 4 partitions in my /dev/sdb total size of a whole drive is 2 TB
in where main partition is of 1TB in size.
however i want to increase this 1TB partition. therefore i added new
3TB /dev/sda and replicated the partition tables with with gdisk.
which worked great.
now the partition that was in the size of 1TB and copied to the new
drive /dev/sda i deleted the partition. and created the new one with
increase size of 2TB.
now i have also attached sda 2TB partition with sdb 1TB partition.
sync is in progress which will probably be synced in few hours.
My question is if i add another new 3TB drive by replace the old 2TB
drive. similarly i copy the partition table from gdisk from old 3TB to
now 3TB. but point of notice is now the size of 1TB partition should
become 2TB. do you guys think this will happen automatically or i have
to make some changes in order to grow the size.
Any help/guidance will be highly appreciated.
Thank,
Yousuf
I'm having difficulty understanding the problem. I think you were saying
that you had a 1T RAID1 partition created from 2 x 1T partitions on 2 x
2T drives. You've replaced one drive with a larger one and made the
partition used in the RAID array larger. You now want to do the same
with the other drive.
Once the second drive is replaced your RAID1 array will still appear to
be 1T in size. However it will appear to be on a 2T device. You need to
resize the array to use the available space then you need to resize the
file system on it since it will still think it is only 1T.
