space left on ext3 (2.6.6-bk3)

[Guennadi Liakhovetski]

On a ext3 fs:

fast:/mnt/tmp# df
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/sda3               958488    521864    387936  58% /mnt

fast:/mnt/tmp# cat /dev/zero > zr
cat: write error: No space left on device

fast:/mnt/tmp# ls -l
total 436624
-rw-r--r--    1 root     root     446660608 Jun 18 00:23 zr

fast:/mnt/tmp# rm zr

fast:/mnt/tmp# df
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/sda3               958488    521864    387936  58% /mnt

Is this an expected behaviour?.. Yeah, it is nice to have more space than 
you think you have, but...

Thanks

436192 blocks

958488-521864 = 436624 blocks

I think you have 5% reserved for root, as this is the default setting
when creating ext3 fs'.

Have you tried running fsck on it?  How many inodes are available.

Oh, I forgot about that again... Wouldn't it be good to have df either
1) report different amounts for root / non-root
or
2) report both
?

Thanks
