I think I got the numbers right, but in any case, this is the gist of the error: PANIC: blkptr at ffff88040b993640 DVA 1 has invalid OFFSET 36830022909049856
What was the last version of ZFS-on-Linux (that you were using) that works? Was that the only version of ZFS you had ever used? Can you attach the output of: sudo zpool status sudo zpool upgrade sudo zdb I assume you have swap on ZFS and this is breaking when it tries to access the swap dataset? If so, can you provide this output (substitute for rpool/swap as appropriate), which you should probably compress: sudo zdb -dvvvv rpool/swap I'm not sure that'll be enough information (as I'm not expert enough to debug at this level), but it should be a start for me to take this to someone else. If it is happening with swap, try moving the swap dataset out of the way, and create a new one: sudo zfs move rpool/swap rpool/swap-broken sudo zfs create -V 4G -b $(getconf PAGESIZE) -o compression=zle \ -o logbias=throughput -o sync=always \ -o primarycache=metadata -o secondarycache=none \ -o com.sun:auto-snapshot=false rpool/swap sudo mkswap -f /dev/zvol/rpool/swap This will hopefully get you working again on the latest ZFS. If you keep the old dataset around, then we may still be able to debug how this happened. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1628553 Title: Ubuntu 16.04.1 Install zfsutils-linux Panic Error, endless loop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/zfs-linux/+bug/1628553/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
