we have rhel 7.6 server with sdb and sdc and sdd disks
the machine is physical machines with disk of 1.7T each of them
we notice the sdd disk displayed from lsblk as
lsblk | grep data
sda 8:0 0 1.7T 0 disk /data/sdc
sdc 8:32 0 1.8T 0 disk /data/sdb
sdd 8:48 0 1.8T 0 disk /data/sdd
sde 8:64 0 1.7T 0 disk /data/sde
but when we do the following in order to find the UUID number as
blkid /dev/sdd
then no output
actually we need to get example as
blkid /dev/sdd
/dev/sdd: UUID="941546ac-2168-4130-b51f-f5a255a4e43c" TYPE="ext4"
what could be the reasons for that and suggested solution?
Note - disk with UUID defined correctly in /etc/fstab
