The filesystem type isn't an option for autopart, unfortunately. The only options autopart supports is regarding encryption. It looks like you'll have to switch to using part to define the partitions. From the documentation: Note that the autopart option cannot be used together with the part/partition, raid, logvol, or volgroup options in the same ...
I'm assuming you're running this against a device that is mounted read/write. Don't do that. You will get errors. Remount it read-only. If it's a critical system filesystem like / (which this appears to be), then boot to single user mode and mount it read-only. You likely have writes to that device in-flight that haven't fully flushed to the block ...
And it keeps contradicting all over Internet. But you expect to get consistent answers here? The only specific recommendation I would make is to forget about ZFS - unless you're running on Solaris (where it makes a lot of sense). Beyond that, how you configure your disks, your I/O scheduler and having spare memory for disk I/O is much more important ...
ZFS and XFS allocate inodes dynamically so would fit the need. I wouldn't bet on ReiserFS.
Try the following: make sure you have a backup, it's a risky mission. Copy you system dd if=/dev/<device_name_fs_is_on> of=/path/to/other/location/filesystem.img bs=1048576 count=20480 Format the new hard drive and create the needed filesystem Copy the file system dd if=/path/to/other/location/filesystem.img of=/dev/<new_device_name> Mount ...
With OS disk you need to partition the disk, because boot loader read the partition table, but with data disk you don't need disk partition, but i recommend to use lvm with ext4, because maybe in a future your space will be gone
You can run any filesystem on a bare block device with or without partitions, however the danger is that both people and OSes expect to see a partition table on a block device to realize that there is data present. (both raw disks and partitions are just block devices, after all) ZFS actually creates such a guardian partition table which is why it's safe ...
Not required, but you should partition. The partition table eats up very little space, but it is universally recognizable. Windows will know that there's a filesystem there if you put it in a Windows box. If you have no partitions, other operating systems will just treat it as an empty drive.
Yes you can format a whole block device and need not create a partition first. On SAN LUNs and multi-boot systems I would recommend creating partitions though and setting the correct filesystem id, as you run the risk that other operating systems and/or operators could interpret a unpartitioned disk as free and unused.
1) Download systemrescuecd http://sourceforge.net/projects/systemrescuecd/files/sysresccd-x86/3.8.1/systemrescuecd-x86-3.8.1.iso/download 2) Add this .iso to the quest OS Ubuntu 3) Start this virtual machine 4) Use zerofree zerofree /dev/sda1 5) Poweroff this virtual machine 6) Use Hyper-V manager (Edit -> defragmentation)
