Re: [Bug 747068] [NEW] /tmp = EXT3, the VM images gives EXT4-fs error
((Ok, this is the first time every I file a bug, so give me also feedback when I report wrong..)) Thanks for taking the time to report this bug. First of all, I want to build a system for production in wich I can build (very) fast new VM's. I installed Ubuntu Server 10.04.2 64Bit as host OS with the following partitions: /Boot [Prim] 1GB (EXT4) / [Prim] 25GB (EXT4) swap [Prim] 25GB (swap) ---extended--- /tmp [Logical] 25GB (EXT4) /var/log [Logical] 10GB (EXT4) lvm [Logical] 1,5TB (lvm) When I use VMBuilder and build to a RAW logica volume (lvm), it takes more than 12 minutes! I'd recommend building a single pristine image (where time to build doesn't matter), and snapshot or copy that when you need a new image and make the few changes you need to. Maybe that was your plan all along, but since you mention the time it took to make the first image, I wasn't sure. Then I tried to change the /tmp partition (of the HOST) to EXT3 and it did take less than 4 minutes Interesting. Are you using a local archive mirror? It's possible that if you switch back to ext4 now it'll go much faster. The only problem now is that the VM gives the following error on startup: EXT4-fs error (device sda1): ext4_mb_generate_buddy: EXT4-fs group 2: 3431 blocks in bitmap, 3597 in gd Any ideas? Is sda1 your tmpfs? If so, edit your fstab to mark it as ext3. Maybe first any ideas for a workaround? Actually long-term for most image building we recommend switching to live-build. If you try that, and your host has enough memory (more than 4G), then building out of a tmpfs can make for very fast, 2-4 minute, image builds.
