Disk Space full

[legolasthehansy]

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.

[legolasthehansy]

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.

[legolasthehansy]

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
