Migrating from HDD to SSD, problems when rebooting [SOLVED]

Burroughs · 2014-05-13 07:52:04

Good morning to everyone!
A few days ago I decided to upgrade my laptop, an Asus U44S, by replacing its original magnetic hard drive with a solid state one.
Well, once gathered some info on the Internet, I proceeded the following way (both hard drives have the same size, 750 GB):

dd if=/dev/sda of=/dev/sdb bs=4096 conv=notrunc,noerror

My partitioning scheme is as follows:

/dev/sda1 >> recovery for Windows; /dev/sda2 >> swap; /dev/sda3 >> /; /dev/sda4 >> extended partition; /dev/sda5 >> /home

Mounted the root partition and then the subsystems:

mount /dev/sda3 /mnt
mount -t proc none /mnt/proc
mount -o bind /dev /mnt/dev
mount -o bind /sys /mnt/sys

then a change root:

chroot /mnt /bin/bash

Edited the fstab by adding the options noatime,discard to the lines rgarding the root and the home partition, added the option elevator=noop in /etc/default/grub, rebuilt the kernel image by giving:

mkinitcpio -p linux-ice

installed grub:

grub-install /dev/sda

after that, unmounted the subsystems and rebooted the machine.
Once selected my kernel, TuxOnIce, Arch immediately goes into emergency mode, because all systemd units fail in their initialization.
Another strange thing, the extended partition containing my /home, isn't mounted.
Where did I go wrong and what should I do to get this mess fixed?

Burroughs.

You should mount the home when you mount the root partition too:
mount /dev/sda3 /mnt
mount /dev/sda5 /mnt/home
mount -t proc none /mnt/proc
mount -o bind /dev /mnt/dev
mount -o bind /sys /mnt/sys
I'm using the ssd too, and I think it's better to not use the swap partition if you have enought ram since the swap it's consuming the ssd faster

Thanks for you answer, but nothing has changed: my Arch still boots in emergency mode and the /home partition is not been mounted...

While in emergency mode can you manually mount the home partition?

Yes, I can, and I'll tell you more, I've solved the problem, it was just an incorrect option in /etc/fstab, that stopped the system from booting up correctly...
Anyway, thanks for your patience and support,

Burroughs.

What was the incorrect option? Curious minds want to know (tm)!

No problem, this is the line:

# UUID=1e6b025c-2759-4fec-9c11-c44a04f8a1ab
/dev/sda5           	/home     	reiserfs  	rw,relatime,user_xattr,noatime,discard	 0 2

Arch boots correctly if I remove the options noatime,discard...
Ok, it's a step forward but I'd like to enable them back again; if you (or someone else) can give me good tips on how to fix this problem...

Ps: I know I'm going off-topic, now. :-)

Put just discard without noatime should work. By enabling noatime you should not use relatime since you can use just one of these: noatime, realtime or atime.

Unfortunately, it didn't work...
If I add only discard, Arch goes into recovery mode again.

AFAIK reiserfs doesn't support the discard option. You'll have to use a different filesystem if you want trim support.

Any reason you are using Reiserfs? Just out of curiosity as I have never seen any one to use it before, especially for a SSD seeming it doesn't support TRIMMING like slithery said. I more see btrfs or ext4 partition more than anything else.

No particular reason at all, just a matter of laziness: I've been using reiserfs since I first installed Slackware, more than 10 years ago, and I've never made a step forward. I agree with you, don't think reiserfs supports trimmering, so there's not much I can do, except migrating my data... :-(

It doesn't at the moment

Wiki

I will be doing a fresh install on a new SSD I have bought. I would do what you have done by moving the entire drive over, but I think a fresh start with a better partition table is in hand.

Brilliant!
I will format my /home partition, instead, reiserfs is really out-of-date and deprecated at the moment and I don't think it's still supported, considering what happened to Hans Reiser.
