1. Get ahold of VMware Workstation 6. 2. Create as many 950 GB sparse virtual disks as you need. Maximum is currently 60 SCSI disks and 4 IDE disks per VM. If more vaporware storage is needed, use nbd^W openiscsid to make the space available as block devices in one central VM. 3. Combine into a RAID array (linear or level 0); less than 16 TB. # mdadm -C /dev/md0 -l linear -n 11 /dev/sd[b-l] # fdisk -l /dev/md0 Disk /dev/md0: 11220.6 GB, 11220601339904 bytes 4. Create filesystem # mkfs.btrfs /dev/md0 fs created on /dev/md0 nodesize 16384 leafsize 16384 sectorsize 4096 bytes 11220601339904 It seems like I hit it early this time - the (virtual) disks were blank this time. 5. Mount # mount -t btrfs /dev/md0 /mnt Segmentation fault 6. Profit?? :-) _______________________________________________ Btrfs-devel mailing list [email protected] http://oss.oracle.com/mailman/listinfo/btrfs-devel
