Disk Space full

legolasthehansy — Wed, 25 Apr 2007 15:46:21 GMT

Hi,
We have a solaris partition exported and which is used a NIS mount point for home directories. It is a 1.7 TB partition. Right now, only 82 GB has been filled up but users get a 'no space left on device' message when they try to touch a file.
Any reason why? We have a similar 1.7 TB partition on the same machine around which 150 GB being used but no problems seen.
Can someone help?

Shalom,

perhaps quotas have been initiated.

Hi,

I forgot to add that quotas haven't been set for the users.
Disk quotas for user xxxxx (uid 6008): none

Given below will make things a bit clearer,

[puneet@lnxs01 ~]$ touch 1
touch: creating `1': No space left on device
[puneet@lnxs01 ~]$ df -kh .
Filesystem Size Used Avail Use% Mounted on
nismaster:/export1/home/puneet
1.8T 83G 1.7T 5% /home/puneet
[puneet@lnxs01 ~]$

Shalom,

This is kinda the wrong place to ask. Its a solaris partition. What does the syslog on the solaris box say?

oops! sorry about that.

Anyways, syslog doesnt say anything. Nothing about the space messages at least.

Some people I talked to told us it might be an issue with Inodes getting run out. I'm not very sure about that. How can Inodes run out of numbers. Or is there a limit for a specific partition?
Thanks.

Yes, Legolamb, many flavors of UNIX set errno = ENOSPC using open(0 or creat() when the filesystem is physically full or out of inodes. We aren't used to seeing that on HP-UX because almost no one creates a vxfs filesystem with a fixed number of inodes.

Your reply was really helpful in giving some new direction on what to do next.
Can you be more specific as to where to tweak back the settings so that I can get back to using the partition.
This would be greatly apreciated.

I'm not at work and don't have a Sun box handy but you should run df -F FSType -o i to list the inodes. You could also get the ENOSPC error if the file system was setup with excessive reserved space that can only be used by root; typically this fraction is less than 10% but I didn't build your filesystem. You should do a "man df" on your Solaris box and it should tell you what to do.

Thank you.
I'll look into this tomorrow morning.

On HP-UX you can use "bdf -i" to print the inodes, used and free and %. I'm not sure it will work on solaris.

Hi,

Using df to Display Inode Usage

The following example displays inode usage on all ufs file systems:

# /usr/bin/df -F ufs -o i
