I have Ubuntu 15.04 x64 installed on my home computer,
the boot is already a SSD, but the /home directory is getting full I bought a larger SSD drive today(Samsung 850 Pro Series 256GB SATA III 6Gb/s 2.5" Internal Solid State Drive (SSD) MZ-7KE256BW), thinking I would just clone the old to the new coworker mentioned just doing a fresh install of Ubuntu on the new SSD and copy the old /Home directory onto it, but getting all the right drivers to get this thing up and running has me a bit shy of doing a fresh install.. everything is working just fine...I want as little down time as possible. here is what I have: red_5@arfcom:~$ df -h Filesystem Size Used Avail Use% Mounted on udev 16G 0 16G 0% /dev tmpfs 3.2G 9.3M 3.2G 1% /run /dev/sda1 39G 16G 22G 42% / tmpfs 16G 96M 16G 1% /dev/shm tmpfs 5.0M 4.0K 5.0M 1% /run/lock tmpfs 16G 0 16G 0% /sys/fs/cgroup /dev/sda5 71G 63G 4.1G 94% /home /dev/sdb2 15G 2.4G 12G 17% /var tmpfs 3.2G 52K 3.2G 1% /run/user/1000 /dev/sdd1 1.8T 48G 1.7T 3% /media/red_5/leia /dev/sdc1 917G 791G 81G 91% /media/red_5/r2d2 /dev/sdb5 901G 483G 373G 57% /media/red_5/c3po I've got 32gb ram and an i7 3770k cpu and a high-end video card, so this thing performs quite well as is. pros/cons/suggestions? |

pros/cons/suggestions? confused. i expect that your "home PC" has an available SATA port? if so, why don't you just add the new SSD, partition it, and mount it as /home-tmp, copy all of your /home files over, unmount it, unmount /home, and remount the new SSD as /home and do whatever you want with the old /home partition space... ar-jedi |

the new ssd is much faster I do have one more sata port available and was entertaining reusing the 'old' ssd when the new one was up and running. the OS will be on the "old" SSD. (mount point /) your data will be on the "new" SSD. (mount point /home) performance: your OS is on the slower, older SSD. there is not a lot of downside to this. your data is on the faster, newer SSD. this is good. your reads/writes are now spread across two SATA interfaces, which will be faster. recovery: separation of OS and data makes recovery easier. old SSD fails? no data lost. get new SSD, install OS, mount /home, you are back in business. new SSD fails? no problem. get new SSD, restore data from backup using the tools on your current OS. you are back in business. just remember, 1) if you have enough RAM (4-8GB should do it), don't use swap on an SSD. 2) enable either continuous or periodic TRIM on the SSD; i am a fan of periodic. ar-jedi |

found this and almost got it to work
https://help.ubuntu.com/community/Partitioning/Home/Moving worked fine until I got down to the "Moving /home into /old_home" finally said fkit and remarked the appropriate line in fstab. winner winner chicken diner thanks for the suggestion |
