The Dell MD storage allows a maximum of 64TB virtual disk. We have some imaging staff that require more than a 100TB of storage preferably in one location.
I'll create 2 x 64TB vdisk on the same dell storage. It is then SAS connected to the server and I'll be using LVM to create a volume group consisting of 2 virtual disk to form a 128TB logical volume.
Say few years down the line. They run out of space and we need to SAS connect a separate dell storage block to the server. Now the server has two separate blocks of storage. I then add more disks from the second block of storage to volume group.
Now the volume group consist of two virtual disk from the first block and two virtual disk on the second block of storage. What would happen when one of the blocks goes offline? Would I then immediately corrupt my volume?
