The workaround is to create a 128M journal via mkfs.ext4 -J size=128
which is the size of journal generally created on a 20G disk anyway. This costs 24k blocks (96M) on a 1G partition - which is about 10% of the free blocks available. When you do this Oneiric's resize2fs now appears to complete correctly (with a 1310720M partition). ubuntu@srv-xqubo:~$ resize2fs xxl resize2fs 1.41.14 (22-Dec-2010) Resizing the filesystem on xxl to 335544320 (4k) blocks. The filesystem on xxl is now 335544320 blocks long. But if you run e2fsck across that filesystem it is heavily corrupted. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/955272 Title: resize2fs fail with very large disks from small source image To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cloud-initramfs-tools/+bug/955272/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
