Subject: Corruption at start of files
Date: Mon, 5 Nov 2012 12:56:06 +0100 [thread overview]
Message-ID: <20121105125606.41c17200@moulinex> (raw)
Here is what I see in my kern.log (see below).
For me this first happened when the filesystem was close to full (less
than 1GB left), but someone on the irc channel mentioned a similar
problem on suspend to ram.
The files that have checksum failures end up with their first 4k filled
with 0x01 bytes. They were seeing a lot of writes; things like firefox
session data and cookie data, plus files that disappeared before I
could call inode-resolve on them.
I was running 3.6.3 when this happened; I've upgraded to -rcs since
but I haven't tried to reproduce the bug deliberately. I didn't see
relevant changes in the changelog.
