I have a Mepis/Debian Linux with kernel 2.6.4, which started recently
to complain about "no space left on device". However, "df"
says that here is plenty of space. "du -sx /" confirms the disk usage
reported by "df", and fdisk gives about the same total partition size
(9373927+ blocks).
The filesystem is ReiserFS 3.6. The logs are truncated but the last
few entries are just programs screaming for disk space.
Is there some limitation of ReiserFS that I should know about ? Anyone
has an idea about what's wrong ?
