    [solved] Help! Problem with paritions!

    Hiya! I have a question, i have two hard drives, a 500 gb one, and a 40 gb one.
    On the 40 gb one, with 4 partitons,

    1. One 1.5 gb swap space
    2. 3 gb /tmp
    3. 15 gb partiton for /boot
    4. and a 20 gb for /root or /

    Now, i need to increase my /root partiton into my /home one, so my root can be a 50 gb partiton. 20 gb from the 40 gb hd, and a 30 gb from the 500 gb hard drive.
    now how can i do this? help please!

    Re: Help! Problem with paritions!

    So, your /home partition currently stuffs tour 500gb HD, right?
    And you want to increase your root partition taking space from that other disk. Thus your root would result splitted in two physical disks (!).

    I'm not sure if that's feasible. It isn't to my humble knowlegde, though. I'd say you'll need to reinstall with a better planned partition scheme.

    BTW, your complicated setup caught my attention. 15 Gb for /boot: why that much? And that many partitions... is it a server? Anyway, best of luck. Perhaps someone else has a more clever idea.

    EDIT: perhaps if you post the output of the following comands at terminal, someone can gain a better understanding of your setup:
    Code:
    sudo fdisk -l
    Code:
    sudo mount

    Re: Help! Problem with paritions!

    Mmmm... first of all, you think you have a swap space, but you haven't any. Swap partition should be listed by fdisk -l. It is generally advised to have a swap partition as big as your ram. Not that serious though (it will be seldom used; some people thinks it's actually a waste of disk space).

    As to the rest, your former explanation was quite accurate.
    Again, I may be wrong, but I think *what you intend to do is not feasible*, for the reason mentioned in my previous post.

    So, some alternate advice: some 300Mb should be largely enough for /boot. You could take almost the entire 15Gb (14.7) to expand the root. You would end up with a almost a 35Gb for root. ¿Should that be convenient?
    in order to do so, start from live, fire up gparted, shrink sdb5 to ~300Mb (apply changes), expand sdb6 to fill the recently freed space (apply changes)
    That may take a while, and is somehow prone to errors in my experience, but it should work. BTW I assume that your sensible data is in sda, thus safe regarding these operations.

    If you finally consider reinstalling, and don't have any serious reason to do otherwise, I'd suggest to keep your /home in sda1 (that's good habits), but no separate partitions for /boot and /temp. Rather root (/) in a new sdb1 resized to say 38 Gb, which will include /boot & /temp as folders, and a new sdb2 of about 2Gb for swap. Both may be primary, no problem. If unsure, you can post a screenshot of gparted (on your sdb disk) before doing permanent changes.

    Cheers

    Re: Help! Problem with paritions!

    Hi,

    I am having a similar problem too. I think after the most recent update this happened. In my case I would like to increase disk space /dev/sda1 for the /. How can I do it?

    Many thanks

    results for fdisk -l and mount is given below.
