Weird boot problems.
by GianPiero Puccioni
Hi,
I have a problem with an old rack unit I use in a cluster. We had a problem
with the HD and had to change it and reinstall. It was done by someone new to
the job (I am locked and doing everything remotely) and he had a problem with
the configuration as it seems that this unit HD HAS to be configured as RAID
and F33 didn't see it at first.
I am not sure what he did try, only thing he said is that it stopped at boot
and he had to comment a line in fstab, but the result is that the unit starts
in weird way.
The situation is this (skipping some lines):
# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 931.5G 0 disk
└─sda2 8:2 0 930.5G 0 part
├─fedora_node06-root 253:0 0 50G 0 lvm /
├─fedora_node06-swap 253:1 0 4G 0 lvm [SWAP]
└─fedora_node06-home 253:2 0 876.5G 0 lvm /home
#fdisk -l /dev/sda
Disk /dev/sda: 931.51 GiB, 1000204886016 bytes, 1953525168 sectors

/dev/sda1 * 2048 2099199 2097152 1G 83 Linux
/dev/sda2 2099200 1953523711 1951424512 930.5G 8e Linux LVM
#ls -l /dev/sd*
brw-rw----. 1 root disk 8, 0 Feb 2 01:00 /dev/sda
brw-rw----. 1 root disk 8, 2 Feb 2 01:00 /dev/sda2
# cat /etc/fstab
/dev/mapper/fedora_node06-root / xfs defaults 0 0
#UUID=f365a320-f3d7-4c07-8bfb-f0164b9ce8c0 /boot xfs defaults 0 0
/dev/mapper/fedora_node06-home /home xfs defaults 0 0
/dev/mapper/fedora_node06-swap none swap defaults 0 0
# ls -l /boot
total 0
So as I understand it sda1 is bootable and contains the kernel, linux start from
there and then finds (how?) and mounts / and /home but not /boot which is
empty. I would have changed the line in fstab with /dev/sda1 but it doesn't
exist (!).
dmesg has this:
[ 4.369576] sd 3:0:0:0: Attached scsi generic sg1 type 0
[ 4.384096] sda: sda1 sda2
so it is there and seen but why the block device is not created?
Copying the content of (sda1)boot into /boot and reinstalling grub could
probably work but how?
Any advice?
Thanks,
GiP

Formatting second hard disk
by Paul Smith
Dear All,
I have got a second hard disk on my desktop computer, which I would
like to format. My machine runs Fedora 33, and I would like to ask you
what format to adopt: the new Btrfs is advisable?
Moreover, could you please direct me to some documentation on how to
format the hard disk? Using GParted?
Thanks in advance,
Paul

Grub peculiarities
by Frank McCormick
I run several distros on my SSD (/dev/sda) including Debian Bullseye,
and Fedora 33.
When Grub is installed in Debian, the startup cfg file generated by
Debian lists the kernel versions in reverse order, with the rescue
kernel first. Fedora lists the kernels in all versions properly.
Several months ago I filed a bug on the Debian bug tracker
but nothing was ever done about the problem.
My question is this: If Fedora can list everything properly, what is the
difference between how Grub is setup on Fedora and how it's setup on
Debian. Is there something in the config files which determines what
order kernels are listed in ?

USB SSD disk speed question
by Frederic Muller
Hi!
I bought a rather cheap but not so cheap 1TB SSD drive advertised at rw
speeds of 450MB/s. I have 2 thinkpads, one X1 3rd gen and one X1 6th
gen. Now here is what happened:
1. On 3rd gen laptop with F32 I tested (and made a full backup) : 45MB/s
(NTFS)
2. I installed a the "brand new" F33, restored my backup and...: 85MB/s
(NTFS)
3. Since I was a tad late updating I told myself let's do it on the 6th
Gen too. Did a full backup on F32 at : ~400MB/s!!! (NTFS and ext4 - did
several backups)
4. I installed a fresh new F33 and the restore speed was then... 50MB/s
:-( (ext4)
5. I just restested the disk on the 3rd gen laptop and I am now (ext4)
at 45MB/s (I also just upgrade my BIOS to its latest version for this test).
So I was wondering if there was any logical explanations and things I
could do to ensure I use the disk at its maximum speed.
Thank you.

Using a Windoze application
by Geoffrey Leach
I have a Windows 10 application on a USB stick. I need to run it
occasionally on a laptop that does not have Windows, but does have
fedora 32.
I could, of course, install Windows, fiddle the partitions, then
install Fedora. Lots of work for something that would be used
occasionally. To say nothing of the annoying rebooting.
Any suggestions on a better approach would be appreciated.
Thanks.
