Topic: Openembedded rootfs size limitation?

I'm still trying to get a good OE build for my big Infocast. When I try to change the rootfs size to something reasonable because I was running out of space, I get an error:

| + ROOTFS_SIZE=600000
| + genext2fs -N 50000 -b 600000 -d /stuff/output-angstrom-.9/rootfs/xfce46-image /stuff/output-angstrom-.9/deploy/eglibc/images/chumby-silvermoon/Angstrom-xfce46-image-eglibc-ipk-v2011.05-chumby-silvermoon.rootfs.ext3
| genext2fs: not enough memory for filesystem
NOTE: package xfce46-image-1.0-r1: task do_rootfs: Failed

Is this a chumby limitation? My sd card is 4 gb so it could easily have two partitions at almost 2gb each..

Re: Openembedded rootfs size limitation?

Bump, does anyone have ANY idea about this?? This is killing me - most of the X based images I am trying run into this issue. I just changed the ROOTFS size but I just don't know what filesystem it is talking about when it says out of memory.

You're meant to change your IMAGE_ROOTFS_SIZE in chumby-silvermoon.conf

[i.e. your 600000 is greater than the image default of ~450000.]

Uh, that is where I changed it. I don't know of any other way to change the rootfs size than editing that file. I get the error when I leave the file untouched. You can ignore that number for the time being, I just get the message no matter what.

Are you running this in a VM?...

Re: Openembedded rootfs size limitation?

No, it's just on my Linux computer that has plenty of hard drive space...not that much RAM, but that shouldn't matter for this issue...

Re: Openembedded rootfs size limitation?

Some more logs to help with the confusion. Note that the 990000 is the root fs size set in chumby-silvermoon so please ignore it - I've tried setting it to various things and it never works.

| ++ du -ks /stuff/output-angstrom-.9/rootfs/xfce46-image
| ++ awk '{size = 10240 + $1; print (size > 990000 ? size : 990000) }'
| + ROOTFS_SIZE=990000
| + genext2fs -N 50000 -b 990000 -d /stuff/output-angstrom-.9/rootfs/xfce46-image /stuff/output-angstrom-.9/deploy/eglibc/images/chumby-silvermoon/Angstrom-xfce46-image-eglibc-ipk-v2011.06-chumby-silvermoon.rootfs.ext3
| genext2fs: not enough memory for filesystem
NOTE: package xfce46-image-1.0-r1: task do_rootfs: Failed

Changing it to something LOWER helped...

Re: Openembedded rootfs size limitation?

You're running out of memory [Why I assumed you're using VM].

genext2fs has a calloc call that requires as much memory as the FS...

Re: Openembedded rootfs size limitation?

Ohh, so by memory they DO mean RAM? Crazy...Will keep in mind.

Re: Openembedded rootfs size limitation?

It appears to me that you are running out of memory here. You are probably running on a virtual machine are you not?  The reason why I said this is because the error stems from a void pointer to a memory allocation that is not there.  If not, then you probably need to buy additional memory or you would just keep hitting this bump again and again.
