 Posted: Sat Dec 15, 2012 5:40 pm Post subject: Replacing laptop hard drive with SSD. |
 |
|
(Maybe this belongs in Kernel & Hardware, not sure) I have a laptop (core 2 duo celeron) that had it's spinning hard disk die some months ago. I replaced it with an older 2.5" disk I had around, but it was smaller so I had to give up my dual-boot windows. I just purchased a 120GB SSD (Samsung 830) and I am wondering what changes I have to make to adjust my system to this device.
Current fstab (minus boilerplate) | Code: | LABEL=BOOT /boot ext2 noauto,noatime 1 2
LABEL=ROOT / ext3 defaults 0 1
LABEL=HOME /home ext3 defaults 0 2
LABEL=VAR /var reiserfs defaults 0 2
LABEL=STUFF /mnt/stuff auto defaults 0 0
LABEL=SWAP none swap sw 0 0
tmpfs /var/tmp/portage tmpfs defaults,size=3g 0 0
tmpfs /tmp tmpfs defaults,size=100m,nosuid,noexec,mode=1777 0 0
tmpfs /var/log tmpfs defaults,size=100m,nosuid,noexec,mode=1777 0 0
/dev/sr0 /mnt/cdrom auto noauto,ro,user 0 0 |
current df -h | Code: | Filesystem Size Used Avail Use% Mounted on
rootfs 9.9G 4.9G 4.5G 52% /
/dev/root 9.9G 4.9G 4.5G 52% /
tmpfs 2.0G 384K 2.0G 1% /run
udev 10M 0 10M 0% /dev
cgroup_root 10M 0 10M 0% /sys/fs/cgroup
shm 2.0G 140K 2.0G 1% /dev/shm
/dev/sda5 25G 11G 13G 47% /home
/dev/sda6 20G 5.8G 15G 29% /var
/dev/sda7 16G 7.4G 7.0G 52% /mnt/stuff
tmpfs 3.0G 0 3.0G 0% /var/tmp/portage
tmpfs 100M 51M 50M 51% /tmp
tmpfs 100M 680K 100M 1% /var/log |
planned fstab: | Code: | LABEL=BOOT /boot ext4 noauto,noatime,discard 1 2
LABEL=ROOT / ext4 noatime,discard,defaults 0 1
LABEL=HOME /home ext4 defaults,noatime,discard 0 2
LABEL=STUFF /mnt/stuff auto defaults 0 0
tmpfs /var/tmp/portage tmpfs defaults,size=3g 0 0
tmpfs /tmp tmpfs defaults,size=100m,nosuid,noexec,mode=1777 0 0
tmpfs /var/log tmpfs defaults,size=100m,nosuid,noexec,mode=1777 0 0
/dev/sr0 /mnt/cdrom auto noauto,ro,user 0 0 |
| Code: | BOOT = /dev/sda1 64M
ROOT = /dev/sda2 25G
HOME = /dev/sda3 30G
STUFF = /dev/sda5 25G (ntfs or fat32)
WINDOWS = /dev/sda6 40G (ntfs or whateve windows want, linux won't touch it) |
I know I should be careful to make sure that all of my parititons start on multiples of 2048 in fdisk, but that this can be done using +G/M for sizes. I don't plan on using swap, but I would like to be able so hibernate. Should I use swap or a hibernation file?
Right now I'm not running {h,s}dparm. Should I be? If so what options should I set? I am running smartd, (which was how I found out my old disk was dieing) the only config line I have for smartd is | Code: | | /dev/sda -I 194 -I 9 -a -o on -S on -s (S/../.././02|L/../../6/03) -m root |
Should I keep that or change it or get rid of it or what? |

| Hibernation does need swap, but at least TuxOnIce can use swap files instead of partitions. In main kernels it may still be possible but with some tweaking. |

| If you want to prevent normal use of swap, you might be able to use the suspend/resume hooks to activate swap just before you hibernate and deactivate it just after you resume. |
