Backups are useful!

I decided to do a hardware upgrade and change the OS to Linux Mint 18.1 (with cinnamon). I wanted to add a 128GB SSD I’d purchased 4 months ago and put the new OS there. I’ve got a sata 1TB boot drive, /dev/sda and 250gb sata in /dev/sdb and a 1.5 TB usb drive for backups on /dev/sdc. The new ssd showed up as /dev/sdd – Now the tricky part: /dev/sda and /deb/sdb have LVM managed partitions.

When the install of Mint 18.1 was finished I saw that it wrote the grub boot stuff to /dev/sda –No No! But it did. I wanted to set the bios to boot from the SSD (dev/sdd) – not going happen my way. One other side effect – when booted into Mint (/dev/sdd) – it can’t see /dev/sda LLVM partitions which is everything important to me! I’m running in LVM group vg--mint and the other drive is group vg--ubuntu. I have yet to find the magic LVM commands to access that other group. But I have that usb backup and it’s current for all my user directories. Getting those backup directories copied properly took a fair amount of time, trial and error.

I can build Shoe3 (minlin) on Mint. It took a while to get Exim4 smarthost working so I can send email from cron or command line. I use the tt-rss newsreader many times each day and it is one diffcult install – apache2,php,mysql or postgres and tt-rss which has a lot status messages about what’s not working — kudos to the author/s

I don’t have the Oraclebox VM’s those are on the unmounted sda/sdb volumes and there are potentially viable setups on the backup drive. I’ve sure where the chroots are but It might be a good time to fix them – I only need one for x86_64 and It could be a more modern version of Debian – maybe only two years old instead of four+ years old. Probably a good thing but it does take time if you don’t remember much about the last time you did this.

Forgot to mention – that SSD is fast. Boot’s Linux minutes faster. Hardly any delay when launching apps – You want one. Maybe I should get a 250GB SSD and stuff it where /dev/sda lives? Maybe, probably not unless …
