hi All, I don't know, whether this is lxc releated, or only ext3. The system is an uptodate Ubuntu Lucid 10.04 x86_64 .
I tried to resize a partition, unser an lxc container. I did it from the host. The partition was mounted on a subdirectory of the container. LXC's version is 0.7.2. The running kernel version is 2.6.32-24-server. There were running also libvirt based KVM machines. resize2fs /dev/<lvm device> This is in dmesg log: [1956101.273405] INFO: task kjournald:1404 blocked for more than 120 seconds.

I restarted the host machine and run e2fsck -f, resize2fs and now it's working. Still I don't know, there wether there is some data loss. Where should I report this? I'm afraid, it's only ext3 related and not depending on lxc?
