Public bug reported:
nvme-cli 2.8-1build2 (in Ubuntu/Noble) shows wrong drive sizes. Compare
the following two.
1.16.3 (Ubuntu/Jammy) output:
# nvme list

2.8.2 (Ubuntu/Noble) output:

Micron_7xxx_Mxxxxxx960TFR 0x1 3.54 GB / 7.68 TB

The difference is this: 1.92 TB vs 15.36 TB, and 960.20 GB vs 7.68 TB.
The drives did not suddenly get bigger, but the problem is described here:
https://github.com/linux-nvme/nvme-cli/issues/2260
And fixed here:
https://github.com/linux-nvme/libnvme/pull/803/commits/00efe8364b0a
This fix is included in:
https://github.com/linux-nvme/libnvme/releases/tag/v1.9
That is not available in the 2.8 version:
# nvme --version
nvme version 2.8 (git 2.8)
libnvme version 1.8 (git 1.8)
But it should be in the Oracular 2.10 one:
nvme-cli (2.10-1) sid; urgency=medium
[...]
* Bumping libnvme build-depends to 1.10.
Suggested patch fixes things, as can be seen here:
# nvme list -o json | grep -vE 'ModelNumber|SerialNumber' >old
(switch to 0osso0 patched build)
# nvme list -o json | grep -vE 'ModelNumber|SerialNumber' >new
# apt-cache policy libnvme1t64
