Hello,

I am at the stage in the handbook after chroot and running emerge-webrxync.

I am getting Errors that says:
tar: portage/dev-java: Cannot mkdir: No space left on device.

However df -h shows:
1% use with 637G available on /

and df -i shows:
1% use with 44726806 IFree on /

After I cancelled the emerge command, I manually tried to create a directory in /usr/portage and that worked fine.

Does anyone have any idea why I am getting the no space error when emerge tries to create a new directory?

koensayr -- That sounds pretty strange. I know this thought pretty basic, but Is your system mounting multiple partitions on mountpoints under / (e.g. usr, tmp, var)? using tmpfs for /var/tmp? (i.e. you could have plenty of space and inodes on / but be short on one of those where portage unpacks). If it is, posting the output of "mount" and showing your /etc/fstab might help.

Sorry if you're already way beyond that - just thinking basics first.

cheers

Thanks for the response, I had figured this out after many hours of digging just before your post.

You are dead on with your answer actually.

I will write a more detailed description of what exactly happened here so hopefully someone else who runs into this similar situation will be helped.

1. My /var is mounted from a different partition than /
2. emerge unpacks into /var/tmp during installation, and /var did not have enough space to unpack everything.
3* the error "tar: ...." message did not give the full path of where the disk had ran out of space. It just showed "portage/....." for directory, therefore, I was thinking it was saying /usr/portage had ran out of space, which was part of / and had plenty of space. Perhaps this can be fixed to show a more useful error message? I don't know if this is part of portage or if it is tar.
4. Apparently, after I cancel the emerge command using ctrl-c, it cleans up the temporary directory, so that when I do a df after cancelling, it shows /var as only being 4% full, this combined with the non-full-path given by the error message made it really difficult for me to figure out what was happening.

Hope this helps someone else in the future.

Hello.
You may have /var/tmp being a link to /tmp
And if you got plenty of RAM, you may also have /tmp be a tmpfs

Thanks. Didn't know about the custom of adding solved to the title. I have done so now.
