Terry,
Some comments, sure to stir up trouble:
Well, not trouble so much as perhaps more confusion. I am comfortable with the partitioning scheme I described and was looking for confirmation on the correct steps to move my system to the SSD. I guess you feel there is a better way of doing it, but now I just have a whole new lot of stuff to try to come to grips with.
1) No need for a separate /boot 2) No need for 8.4GB of swap. 1, max
There will only be one swap, the one on the SSD. The swap on the old disc will go when I reformat and rearrange the data that doesn't go onto the SSD.
3) 50gb / partition? really? How much stuff do you have installed?
Not 50 GB...currently / has about 26 GB on it.
4) Why are you painting yourself into a corner using physical partitions?
Well I don't see it quite that way. This arrangement has been satisfactory for quite a while, and is unlikely to be a problem.
Personally, I'd create one big PV on the disk, create a 10gb LV for root, and however much you actually need (and a bit extra) for home Grub can boot from it fine, and it'll give you flexibility for growing where needed later.
The fact that I was using such a setup when I moved from spinning disk to SSD made my transition much easier:
Are the following steps what you are suggesting I use, or what you used to move from one PV to a new one?
1) Physically install SSD, boot as normal 2) pvcreate a PV on it. 3) vgextend the VG onto the new PV 4) pvmove all extents off the old PV onto the new PV 5) vgreduce to remove the old drive from the VG 6) grub-install to put grub on the MBR 7) shut down, remove old spinning disk
The old spinning disk stays as additional data storage, for the less used stuff.
8) put feet up and enjoy the SSD
and the fstab stuff, should I use tmpfs, and make other SSD specific changes? I appreciate your help, but would really appreciate someone confirming that the steps I outlined are OK, and clarifying those few specific issues that I had...then, with a bit more homework by me on LVM, maybe I can make a decision on how I should proceed.
