Resizable Linux images - not expanding

[Wayne Workman]

I’m running FOG r6483, on Fedora 23.

I just updated an image I have of Fedora 23, it’s a resizable image type - just one disk, it uses ext4 (not lvm).
The computer has a 128GB SSD in it - it’s worked fine in the past many times with fog and re-sizable images both with windows and Linux.

After uploading my new image, and then re-downloading it to test, I’ve noticed the partitions are not being expanded.

I’m going to guess you stopped upload at one point and restarted it? I say this because the d1.partitions is identical to the d1.minimum.partitions.

I’ve been testing the Linux images for expanding and shrinking and can only replicate this if I cancel the upload process before it reexpands the disk.

[Wayne Workman]

@Tom-Elliott I canceled the download process (after uploading) because I realized my nodes had not replicated yet. I didn’t cancel an upload process.

[Wayne Workman]

So this is a non-issue. Turns out, the reason it didn’t expand was due to the image being corrupt from replication failure in this other thread: https://forums.fogproject.org/topic/6793/replication-failure

After I blasted the images on my slave storage node and let them all replicate over fresh, I deployed this image to the same hardware using the same version of FOG and it expanded exactly as expected.

[Wayne Workman]

Actually, only / got expanded using all that is available on the drive… the /home partition did not get expanded.

That’s OK though - I can work with that at least.
