Increase Linux partition size

[asela115]

hi All,

this should be probably a already asked question but highly appreciate if someone can guide me on this

i have a business critical linux system (which is running a SMS system) where one of it's partition size is shrinking
i want to know the possible options of increasing the size of that partition without having any downtime(system reboot etc..).

fdisk and df -h outputs are as below (the partition with issue is bases)

{lkcopr01 bdb2]# fdisk -l

Disk /dev/cciss/c0d0: 72.8 GB, 72833679360 bytes
255 heads, 32 sectors/track, 17433 cylinders
Units = cylinders of 8160 * 512 = 4177920 bytes

AFAIK you can't resize any mounted partition, or make any other changes to it. You need to boot from another drive, either a CD/DVD, USB drive, or another internal drive, before you can resize your partition. I don't know of any other way to do it.

I concur with the opinion of sgosnell.

Yes. At the time of OS installation itself you need leave some free space for later use(increasing the FS etc). Once partitions is allocated and OS installed there is no chance of increasing there size.

You are going to have downtime.
