Resize2fs taking too long and no HD activity apparent

gvsopic · 08-30-2009, 06:45 PM

Hi,
I have a system running gentoo on /dev/sda3. I booted off of a USB stick running Ubuntu and fired up gparted to resize sda3 so I could have some space to try ubuntu out for a change. It seemed alright at first running the e2fsck and showing 3.6% for non-contiguous inodes. Upto here my HD was spinning nicely and the LED for HD access was solid on for a good 15 minutes (the whole HD is 40 GB and I tried to resize /dev/sda3 from 36 to 24GB). Now it's been stuck on the resize2fs for nearly 3 hours with scarcely any HD activity. Running top, I could see that resize2fs was consuming a good bit of CPU, nearly 70%.
Any ideas?
Thanks
GV

Hi gvsopic,

Interrupting a partition resize operation has a high possibility of being fatal, leave it as long as you can.

.. you do have a backup dont you ?

cheers,

kbp,
Thanks for the reply. Yep, leaving it be did do the trick

I was just worried I wasn't seeing much activity from the disk, I suppose resize2fs does more number crunching than disk access, though I could really find a resource to explain the lower-level intricacies of resize2fs, I assumed it was defragmenting the files that had fragments beyond the newly adjusted boundary of the partition.

Here's the output, not sure why it did so many moves and right shifts, looks like it tests the operation first and then actually carries it out...
