Isidoros I think your problem was the same mistake I made cloning a disk.
When you reinstall the new disk you need to create a new UUID for it and then edit /etc/fstab and change the new disks UUID to that. check: $ more /etc/fstab and see if you have a duplicate UUID listed The problem occurs because in the cloning the UUID gets cloned also so you end up with 2 disks with the same ID. At boot time it becomes kind of a random choice which one gets recognized and which one doesn't and I found that they choice can actually switch back & forth which confuses you even more execute the cmd: $ man uuidgen it will show you how to generate a unique/new UUID for your disks On Fri, Jun 17, 2016 at 2:44 AM, ISIDOROS <imou...@hotmail.com> wrote: > i'm facing the same issue with mdadm raid mirroring disks. > > I have cloned my original sda disk to the new sda disk (via clonezilla). > The original disk has configured to use raid mirroring but only one > brick (the current one) is available. > > After finishing clonezilla restoration, i have added a brick to raid > mirroring for sdb disk. > At the end i have updated grub to both disks. > > I have done this to almost 300 machines.
