[Bug 341310] Re: JBD: barrier-based sync failed on dm-0:8 disabling barriers
I have this problem on lucid (on amd64). I don't know if it counts but system was installed as jaunty, and after the usual upgrade process between that and lucid, I see now this error in the kernel log. However I have no idea if it's dangerous or not. Does it cause performance regression? Just because the filesystem I/O seems to be slower, but it's just a feeling. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/341310 Title: JBD: barrier-based sync failed on dm-0:8 disabling barriers To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/341310/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

So it seems to be minor issue. http://www.novell.com/support/search.do?cmd=displayKCsliceId=SAL_PublicexternalId=3907838 I've added option barrier=0 on the line in /etc/fstab to silent the error. What is strange is that I have 2 partitions mounted as EXT4. * The first one is on sda2 and is mounted with barriers enabled * The second is on dm-1 (luks encrypted partition) and gives the above problem Maybe there's some interference with LUKS feature. -- JBD: barrier-based sync failed on dm-0:8 disabling barriers https://bugs.launchpad.net/bugs/341310 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
