Description Pavel Raiskup 2022-11-20 07:33:24 UTC
With i3.large machine in AWS EC2, there's 1 x 475 NVMe SSD.

-----------------------------------------------------------------------
The normal layout on our copr builder i3.large machines (Fedora 35) is:

NAME        MAJ:MIN RM   SIZE RO TYPE MOUNTPOINTS
xvda        202:0    0     6G  0 disk 
├─xvda1     202:1    0     1M  0 part 
├─xvda2     202:2    0   500M  0 part /boot
├─xvda3     202:3    0   100M  0 part /boot/efi
├─xvda4     202:4    0     4M  0 part 
└─xvda5     202:5    0   5.4G  0 part /home
                                      /
nvme0n1     259:0    0 442.4G  0 disk 
├─nvme0n1p1 259:1    0    16G  0 part /var/lib/copr-rpmbuild
└─nvme0n1p2 259:2    0 426.4G  0 part [SWAP]

-----------------------------------
After upgrade to F37, there's just:

NAME    MAJ:MIN RM  SIZE RO TYPE MOUNTPOINTS
xvda    202:0    0    6G  0 disk 
├─xvda1 202:1    0    1M  0 part 
├─xvda2 202:2    0  500M  0 part /boot
├─xvda3 202:3    0  100M  0 part /boot/efi
├─xvda4 202:4    0    4M  0 part 
└─xvda5 202:5    0  5.4G  0 part /home
                                 /

But this is reproducible even with a freshly started Fedora 37 machine,
just go to https://alt.fedoraproject.org/en/cloud/ , start a i3.large
machine from Fedora 37 x86_64 Cloud Base AMIs - and the nvme machine
is not visible.

Tested kernels, the same behavior with all of them:

kernel-core-6.0.8-300.fc37.x86_64
kernel-core-6.0.9-300.fc37.x86_64 (updates-testing)


How reproducible: 100%

Comment 1 Pavel Raiskup 2022-11-21 09:16:07 UTC
I just tested F37 Cloud with i4i.large, and nvme controller works fine there.

Comment 2 Aoife Moloney 2023-11-23 00:33:38 UTC
This message is a reminder that Fedora Linux 37 is nearing its end of life.
Fedora will stop maintaining and issuing updates for Fedora Linux 37 on 2023-12-05.
It is Fedora's policy to close all bug reports from releases that are no longer
maintained. At that time this bug will be closed as EOL if it remains open with a
'version' of '37'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, change the 'version' 
to a later Fedora Linux version. Note that the version field may be hidden.
Click the "Show advanced fields" button if you do not see it.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora Linux 37 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora Linux, you are encouraged to change the 'version' to a later version
prior to this bug being closed.

Comment 3 Aoife Moloney 2023-12-06 11:28:35 UTC
Fedora Linux 37 entered end-of-life (EOL) status on None.

Fedora Linux 37 is no longer maintained, which means that it
will not receive any further security or bug fix updates. As a result we
are closing this bug.

If you can reproduce this bug against a currently maintained version of Fedora Linux
please feel free to reopen this bug against that version. Note that the version
field may be hidden. Click the "Show advanced fields" button if you do not see
the version field.

If you are unable to reopen this bug, please file a new report against an
active release.

Thank you for reporting this bug and we are sorry it could not be fixed.
