Did you install DSL? Or are you running it from the CD?

The output of the program are as as follows:

#df -h

I installed it on a usbflash drive.

Please help me!!

Can anybody help me??

hello !!
Isn't there anybody in this fourm who can help me !
Please please help !!!!

ok, so you have DSL on usb drive? is it the /dev/sda? what partition is /dev/root.old?
Do you just want to resize the partition? do you have unallocated space before/after it?

Boot with a live CD and try resize2fs on the partition (the pratition should not be mounted)

I couldn't unmount this partition .It is in ext2 file system.How can i do that?

Boot with a live CD it will be automatically unmounted

I used resize2fs to expand the sda2 partition to 2.7 gb but the size of /root is still 2.9mb. As it cannot be expand from live cd because the os installation is frugal.How can I unmount the /root partition?

Thanks for reply

You do realize that when you boot from a live cd the root partition is different than the root partition of your installed system, right?
what partition is mounted as root in your system?

DSL is a good little distribution but it hasn't been supported for some time and won't be.
What is on that 1.8GB FAT32 partition?
Were you ever able to boot DSL on the USB? With a root folder of 2.9MB, I don't see how you could since the iso image file is around 50MB.
If you were able to boot it, what changes were made before this problem occurred?

OK,let me make it clear!!
I am not talking about the /(root partition) here,I am talking about /root folder which is by default 2.9mb in size on dsl.
I did the usb-hdd install of dsl which by default makes two partition .One is the ext3 where all the OS data is located with the size of 50mb and the remaining are fat partition which contains mydsl extensions.The usb installation is similar to that of live CD,usb-install too contains the compressed knoppix image file and kernel boot loader etc.I guess to re-size the /root folder it should be booted from flash drive itself.
I tried
but it couldn't re-size because it was mounted.I tried to unmount but couldn't unmount it.
I guess I explain the problem as possible I can!!

Please help!!

you mean the root's home folder? Is it on a separate partition then? or is there a quota or something?
why do you resize /dev/root then? dev/root is the / (root partition)

use the Logical volume manager LVM ,

Are the / and /root the same thing ??I guess the root folder is inside /partition . If / and /root are same how can I increase Its size it's size .Its only 2.9 mb as shown by but the whole partition made by dsl is 51mb !!I guess that is root

From the output of the df you posted I can see nothing that indicates that the /root directory is not part of the rootfs ('/' filesystem). So, it appears to be limited by the size of /dev/root.old (whatever that is?)

'dsl' is not a normal distro, and gets up to all sorts of shenanigans with unionfs, loop devices and god only knows what else. Unless there's an experienced dsl'er lurking on these boards I suspect all you're going to see is incorrect advice and useless questions from people who really don't know what they're talking about.

Sorry I couldn't be of more help, but I don't know what I'm talking about either when it comes to DSL. But at least I know I don't know. ;)


Perhaps you'd be better off just trying another distro.

The reason there aren't very many reponses is that the OP is basically booting a live-cd on 1 partition, if it were a partition I could offer assistance, live-usb is quite tdifferent than an instaled system.

Ok, so in order to get at least a faint idea of what I'm talking about, I downloaded latest iso of DSL. I burned it, booted from a cd and made a USB pendrive install on a 128MB flash disk. It didn't give much chance to influence partitioning of the USB drive, but I could do that if I created the bootable USB manually.

I booted from the usb and, indeed, the output of df was similar to the one posted earlier. in fstab and mtab, however, the /dev/root was (if I remember it correctly) /dev/sda. The distro is on one of the partitions on the usb in the form of image, so I guess there's no simple way to change its configuration except for modifying the image or making your own distro. I don't have much experience with the unionfs, but I guess that the layout of the system is partially in RAM and partially on the usb drive.

The /root (root's home folder) indeed has 2.9 MB available with over 600kB already used. It seems to be a filesystem that doesn't exist physically on the usb drive, so repartitioning will probably not work here. I was, however, able to create 100+ MB files in /usr, /bin, /lib and /home/dsl so you can install additional software if you need it or store data in the regular user's home. If you need to save something that will not disappear after reboot, you can save it on the 1.8GB partition of yours. The only limitation is the 2.9 MB in /root which does not really matter since you shouldn't work with the usb system as root anyway, just use sudo instead.

So my advice is: just deal with the 2.9MB /root it does not limit you in any way. If you can't deal with it, try another distro.
