filesystem "/dev/root" is full

[chad_c]

Hi. Can anyone shed some light on what the following message refers to and how to remedy it. We we are receiving it on our OVO 7.5 unix 11.11 server?

The filesystem "/dev/root" is full

your root file system is full. Use bdf command to see it.

you need to find out any "core" files or any big files might sitting at / level. Remove them to reduce the filesystem.

Hi:

Your root filesystem is full. You can see where space is used with:

# du -kx / | sort -k1rn

One common cause of full root filesystems is a mis-typing of a tape device filename when doing a backup.

If you specify '/dev/rmt/om' [the letter 'o'] instead of '/dev/rmt/0m' [with a zero] you create a regular, usually very large, file in '/dev' thus filling the root filesystem. Therefore, look for non-special files in '/dev' also!

Regards!

Thanks for the info. Not sure why it is saying /dev/root is full. The bdf command shows / to be at 91%.

/dev/vg00/lvol3 20971520 19171560 1787384 91% /

is /dev/root referring to / (root)

the original message is:

msgcnt 11 vxfs: mesg 001: vx_nospace - /dev/root file system full (1 block extent)

Yes, /dev/root is referring to /. Usually what happens is the system was booted in LVM maintenance mode that brought up to multi-user mode with the "init 3" command, rather than rebooting normally.

This thread sheds some light on the subject:

The real key is WHEN did this message occurr?

If you are seeing this from withing OVO or dmesg, then you need to check syslog.log. That will give you a date and time that this happened.

The message appeared a couple of hours ago in our OVO java gui.

However the syslog does not make reference to the actual message we received. There are a bunch of the following message in the syslog that we do not know what it means...

Oct 12 00:00:10 txovo remshd[8315]: wtmp:open: /var/adm/wtmp Value too large to be stored in data type

[Pete Randall · Accepted solution]

Since you're at 91% now and bdf shows that / is correctly mounted (not as /dev/root), I wouldn't worry about it. It was apparently a temporary thing.
