ext3 - No space left on device
 
This is on a Red Hat Linux release 9 system. It is an ext3 filesystem.

[root@cerberus scr_cerb]# mkdir anne
mkdir: cannot create directory `anne': No space left on device
[root@cerberus scr_cerb]# touch anne
[root@cerberus scr_cerb]#

There are free inodes and free space:

[root@cerberus scr_cerb]# df -i /scr_cerb
Filesystem Inodes IUsed IFree IUse% Mounted on
/dev/sdb1 538656 329305 209351 62% /scr_cerb
[root@cerberus scr_cerb]# df -k /scr_cerb
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sdb1 735227752 488355612 210104980 70% /scr_cerb

I have done a fsck of the system which shows that it is clean. Other methods of creating files such as dd if=/dev/zero of=anne fail.

du agrees approximately with df, so there no discrepany concerning the amount of space actually used.

If you have any suggestions for anything else to check, or how to solve this problem, I would really appreciate it.

wow ! That is strange !
Try dump2efs and see what are the numbers for:

Inode count:
Block count:
Reserved block count:
Free blocks:
Free inodes:

Thanks marozsas.

The inode numbers agree with df -k, and the block count agree with the total space.

However, the number of free blocks is off:
246948012 (61737003 * 4096 / 1024)

(246948012 vs 210180852):

[root@cerberus projects_new]# df -k /scr_cerb
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sdb1 735227752 488279740 210180852 70% /scr_cerb
[root@cerberus projects_new]#

However, du shows 540745960 used, as compared with df488279740 above. Someone told me due to sparse files, this discrepancy was ok.

...uselesss...I was expecting to read a large number for Reserved block count.

Another idea: try to mount this filesystem as ext2, to check if the jornal has something to do. If you are successful, try to re-create the jornal.

see'ya,

Try df on all your partitions.
