Hi folks, When I create multiple snapshots on a logical
volume that is being busy written to, the lvcreate command becomes dead when the
third or fourth snapshot is created on a single logical volume. The process
that writes to the logical volume also dies. “Dies” here means the program
doesn’t return, nor can it be killed by pressing CTRL-C or “kill” command. The
system is still responsive though, and I can login to run some other commands.
But once the error condition happens if I run any command that accesses the logical
volume, it also dies. This problem was found
on Fedora Core 4 (2.6.11-1). I also tried it with the unstable dm patches and it
doesn’t cure. Is this a known problem? I’ve searched the Internet
and found some folks discussing I/O scheduler issue in 2.6 kernel snapshot. Any
plan to fix it? Thanks, Charles |
