This is the first question I've had to post in 2 years of using linux, who says its not easy to use
! Anyway down to business....
I've got a 3x400gig software raid 5 array running on Ubuntu 10.10 in my file server. The array is running well and was installed and managed by mdadm.
I'd like to add more capacity to the array but I don't have enough spare sata ports to set up a larger capacity array and move the data across.
Would it be possible to swap, one by one, the 400gig drives with larger drives to increase the size of my current array? i.e. have 2 400gig drives and 1 larger drive, wait until the array has rebuilt, add another drive, wait until its rebuilt, add the final drive, then hopefully increase the storage capacity of the array?
I am aware you can add drives to an existing raid 5 array but I don't have enough spare ports (or enough space in the case!) to do this.
I've been hunting round many forums for advice but I've not found anything useful so far, any advice you guys can give would be really helpful!
