My Software RAID5 is saying No Space left on Device when it's not full


I have had a software raid running on OpenSuse / SUSE 10 & 11 for some time and I have about 8TB on it. I always run close to 100% and once in a while get there but always manage to delete a bunch and clear out about 30-100GB.
For some reason recently (last several months) I get:

Filesystem 1K-blocks Used Available Use% Mounted on
/dev/md0 7813819904 7783541772 30278132 100% /space

but even though it shows 30GB

# cd /space

# touch foo

touch: cannot touch `FOO': No space left on device

I did an xfs_repair on it and I did a "df -i"

# xfs_repair /dev/md0

Phase 1 - find and verify superblock...
Phase 2 - using internal log
- zero log...
- scan filesystem freespace and inode maps...
- found root inode chunk
Phase 3 - for each AG...
- scan and clear agi unlinked lists...
- process known inodes and perform inode discovery...
- agno = 0
- agno = 1
- agno = 2
- agno = 3
- agno = 4
- agno = 5
- agno = 6
- agno = 7
- agno = 8
- agno = 9
- agno = 10
- agno = 11
- agno = 12
- agno = 13
- agno = 14
- agno = 15
- agno = 16
- agno = 17
- agno = 18
- agno = 19
- agno = 20
- agno = 21
- agno = 22
- agno = 23
- agno = 24
- agno = 25
- agno = 26
- agno = 27
- agno = 28
- agno = 29
- agno = 30
- agno = 31
- process newly discovered inodes...
Phase 4 - check for duplicate blocks...
- setting up duplicate extent list...
- check for inodes claiming duplicate blocks...
- agno = 0
- agno = 1
- agno = 2
- agno = 3
- agno = 4
- agno = 5
- agno = 6
- agno = 7
- agno = 8
- agno = 9
- agno = 10
- agno = 11
- agno = 12
- agno = 13
- agno = 14
- agno = 15
- agno = 16
- agno = 17
- agno = 18
- agno = 19
- agno = 20
- agno = 21
- agno = 22
- agno = 23
- agno = 24
- agno = 25
- agno = 26
- agno = 27
- agno = 28
- agno = 29
- agno = 30
- agno = 31
Phase 5 - rebuild AG headers and trees...
- reset superblock...
Phase 6 - check inode connectivity...
- resetting contents of realtime bitmap and summary inodes
- traversing filesystem ...
- traversal finished ...
- moving disconnected inodes to lost+found ...
Phase 7 - verify and correct link counts...
done

=====================================================

#df -i

Filesystem Inodes IUsed IFree IUse% Mounted on
/dev/md0 121411920 299392 121112528 1% /space


Any Ideas? I should have 30GB free right?

Thanks,
Tom

df -l

/dev/md0 7813819904 7791349772 22470132 100% /space

It's not that I have space! It's like I am running out of inodes even though
the df -i is supposed to show that. I removed about 1000 files or maybe even
more that I didn't need and it works. The test I used was I did a:

# touch foo - File was created
# touch foo1 - got "File System Full"

deleted any file and was able to create "one" file so I
am guessing it was something to do with the inode table
and now that I have removed about 1000+ files it will
take a long time to get back to that plus I am changing
it.

Thanks anyways for your suggestion and help!

Tom
