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

# 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
