Last week there was a momentary power outage and the external MediaSonic
Probox shut down (it's on a surge protector, will be re-attached to a UPS.)
When I noticed this the following morning and turned on the Probox lsblk
reported their identification as /dev/sdf through /dev/hdi. In /etc/fstab
they were the previous names, /dev/sdc through /dev/sdf. Using the UUIDs for
each drive I labeled /dev/sdc1 "data2" and /dev/sdd1 "data3". Both /dev/sde1
and /dev/sdf1 already had PARTLABELs. I editied /etc/fstab using the labels.
Yesterday evening another momentary power outages. The desktop was rebooting
and I turned on the Probox and assumed the drives there would be mounted. No
such luck.
This morning I had no backup reports. Checking 'mount' the Probox drives
were not mounted. Trying to mount them failed as the kernel didn't find
them.
Using lsblk I see the names were returned to /dev/sdc through /dev/sdf:
# lsblk

But, when I run 'fdisk -l' I don't find any labels:

What have I done incorrectly that there no longer are LABELs or PARTLABELs?
And how do I name/label the Probox drives using readily identified names
rather than the UUIDs?
TIA,
Rich
