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

sda 8:0 0 931.5G 0 disk
└─sda2 8:2 0 930.5G 0 part

/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
