Public bug reported:
I'm running into an issue when attempting to remove a large number of
hardlinked files on Jaunty. Here's the background:
- The server is running mdraid + lvm, with the file system under load formatted
as ext4.
- I use a script to rsync a remote server with the --link-dest parameter daily.
- Once a month, I remove the oldest backups with a command such as sudo rm -rf
200906*.
Within a few minutes, the system stops responding to anything other than
a ping. I attempted to get a kernel panic log by booting in single user
mode and running 'setterm -blank' to disable power saving, but
apparently when it panics it kills the display as well. I'm using a
bluetooth keyboard, and the system won't respond to it either.
I didn't have any problems like this when the file system was previously
formatted as ReiserFS. I should also note that I currently have
e2fsprogs and its dependents installed from Karmic to avoid the resizing
FS data loss bug. However, I don't think those packages are related to
the current freeze.
I'll be posting more info soon, it just takes a long time for the server
to check quotas after a crash :).
