Hi, could someone give me clues about how to extend the storage?
Currently I have two 4TB drive in Raid 1. Recently the space is not enough, so I buy a new 8TB disk and hope to have a 8TB Raid 1 storage. That is
sdb and sdc forms a RAID 1, so available space is 4tb
new /mnt/sdd (8tb)
sdb and sdc forms a Raid 0, and then do Raid 1 with sdd, so totally 8tb available
But I have no experience to achieve it, so some questions need your help:
1. can this be done simply in web gui?
2. I guess the idea is to physically remove one of the 4TB disk, then insert new 8TB disk and do sync. Finallly install the removed 4TB disk back and convert those two 4TB disk to Raid 0. is this correct? If possible, please teach me more details. Thanks
