Hi all, I think we just hit the same bug on a Production server today, with a snapshot on the root filesystem. Here are the relevant logs :
kernel: [455151.056975] INFO: task jbd2/dm-0-8:214 blocked for more than 120 seconds. kernel: [455151.149417] INFO: task dmeventd:27193 blocked for more than 120 seconds. kernel: [455151.241272] INFO: task cat:27522 blocked for more than 120 seconds. ... All I/Os on the filesystem were blocked, so we had to reboot the server. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1645636 Title: deadlock during lvm snapshot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lvm2/+bug/1645636/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
