[SOLVED] Remove hard drive

peterpeter · 2013-08-25 02:23:31

I set up Arch Linux with a hard drive /dev/sdc connected to the computer. I now want to remove this hard drive completely. However on boot (using Syslinux with no chain for this hard drive) the system stops at the start job for that device.
If I plug the hard drive back in (connect sata cable) all works well again.
Where do I remove the device so that the boot process does not expect it to be connected.
Thanks

Without anymore information, I wouldn't know what to say, but the /etc/fstab file has all the information about what filesystems are to be mounted and where they should be mounted. So:
1) could you post your /etc/fstab file please?
2) what does your machine actually say when it kicks up the error?
3) are you using a set-up like LVM or RAID?

Thanks clfarron4,
The device /dev/sdd1 is not listed in fstab. I can mount it using sudo mount or using Dolphin (KDE on Arch Linux) if I want to.
If the hard drive is not plugged in, the boot message is: a start job is running for dev-sdd1.device
This then times out
History is that I installed Arch on another hard drive with Linux Mint on sdd1 using grub and os-prober. I assume that the system (the kernal?) now expects to find that hard drive and boot fails if I disconnect it.
Presumably there is a way of telling Arch that the device is not there, but I do not know what file to modify.

I am not using LVM or RAID

Could you post the ouput of

lsblk

and

cat /etc/fstab

and

cat /boot/syslinux/syslinux.cfg

Edit:
also, have a read here https://wiki.archlinux.org/index.php/Pe … ice_naming

I would suggest referencing your filesystems by uuid in your /etc/fstab, and /boot/syslinux/syslinux.cfg files

*Although it sounds as though you are trying to mount something that is not there

Please use code tags.

Your problem is that, when you remove sdc, sdd becomes sdc in it's place. Rewrite your fstab entry for Windata to use UUID or label identification.

Sometimes experience is required to see the obvious.

Thanks WorMzy
