Ubuntu: No space left on device

+3 votes

I've discovered in syslog that postfix is reporting

postfix/cleanup[31051]: warning: mail_queue_enter: create file incoming/407669.31051: No space left on device

I also have problems with boinc suddenly stopping, apparently because it loses its connection to localhost. I don't know if this is connected.

df reports that all disks have plenty of space (root is only 40% used), no swap is being used, the waste bin is empty, and disks appear to be healthy. Any suggestions as to what might be causing this?

I'm using 14.10, with 3.16.0-25-generic.

What is your output for df -i ?
I've since rebooted as other apps became problematic. Currently, the IUse% on root is 14%. Most are about 1% - 5%

Any other syslog messages stand out? Googling around points to a possible reservation of space for root issue.

http://serverfault.com/a/93613

 tune2fs -l /dev/sda1
 The entry to look at is Reserved block count and multiply it by Block size to get bytes reserved

Other posts on the http://serverfault.com/questions/93606 page reference 'message_size_limit' so that might be worth checking. I'm guessing that it's probably not going to be your problem though.

I didn't think to ask earlier for the output from df -h. What does the space on other volumes (such as where /tmp is mounted) look like?

I want to get rid of mac os x but it seem the mac os firmware are not compatible with current linux? So I have to keep the mac os partition and mac os.
Is there anyone who managed to remove mac os x entirely and will 16.04 be able to do this?

I am wondering how - or more exactly where - umask is defined on a stock Ubuntu server system.

I have reactivated the root account. Here's the respective default umask for root and normal users:

Nomal User:

$ umask
0002

Root User

$ umask
0022

On RHEL/CentOS, these values are defined in /etc/bashrc and then in the individual ~/.bashrc files. How does Ubuntu handle this?

I'd like to install a master on a virtual machine and rsync this installation to ten clients (desktop installation for a library). Also, all changes after the initial installation to this master image should be replicated to them.

There are some modifications for the master installation necessary. It must not use UUIDs for example.

Is there a ready-to-use script for this scenario?

Thank you in advance.
