I had a CentOS install with 2 disks. SSD(sda) for boot, swap and root. HDD(sdb) for data mounted in /hdd. All partitions except boot are lvm. I "replaced" the disk with a bigger one (deleted smart array for raid1 with 2xHDD and created a raid5 3xHDD smart array). Tryed creating a sdb1 (lvm) partition with GParted live (8TB partition) but it won't let me. Now after reboot I get booted in maintenance mode. How and where can I delete the old records for the sdb1 partiton and create the new partitons? Or how does one fix this problem? The only record I found of the old partition is the record in fstab.
Tryed with parted but it still won't create partition.

needed to run dd if=/dev/zero of=/dev/sdb bs=512 count=1 conv=notrunc after I could create the partition with no problem!
