I have a Dell r710 running Debian and just got it tuned to my use. It boots from a RAID 5 array of 4x300gb SAS drives. I have just converted some 600gb NetApp drives to 512 sector and they are recognised. How can I migrate the entire system from 4x300gb drives to 4x600gb drives without data loss and messing up the OS from booting? Of course I want the resultant array to make full availability of the storage size increase.
Is it possible to swap one disk at a time using the RAID bios to rebuild the array? After all there is one disk redundancy.
I saw this thread: community.spiceworks.com/topic/… and wondered if this would work in my case:
replace 1 disk a larger disk let RAID rebuild replace another disk with a larger disk let RAID rebuild replace last disk with a larger disk let RAID rebuild At this point, the controller should allow you to expand the vdisk.
I have eight bays in total. the other four store media files so could be commented out of
fstab temporarily and removed if thats the better way to go.
Also, the original running 4x300gb is not full: 428gb free out of 788gb
