With Solaris 11 coming out with a requirement of ZFS on the root disk, I was curious to know who is using the Zeta File System now?
I have been using ZFS for the past year and don't plan to go back to UFS since ZFS is much more reliable and easier to maintain. (13 Replies)

mkfs.btrfs
MKFS.BTRFS(8) System Manager's Manual MKFS.BTRFS(8) NAME
mkfs.btrfs - create an btrfs filesystem SYNOPSIS
mkfs.btrfs [ -A alloc-start ] [ -b byte-count ] [ -d data-profile ] [ -l leafsize ] [ -L label ] [ -m metadata profile ] [ -n nodesize ] [ -s sectorsize ] [ -h ] [ -V ] device [ device ... ] DESCRIPTION
mkfs.btrfs is used to create an btrfs filesystem (usually in a disk partition, or an array of disk partitions). device is the special file corresponding to the device (e.g /dev/sdXX ). If multiple devices are specified, btrfs is created spanning across the specified devices. OPTIONS
-A, --alloc-start offset Specify the offset from the start of the device to start the btrfs filesystem. The default value is zero, or the start of the device. -b, --byte-count size Specify the size of the resultant filesystem. If this option is not used, mkfs.btrfs uses all the available storage for the filesys- tem. -d, --data type Specify how the data must be spanned across the devices specified. Valid values are raid0, raid1, raid10 or single. -l, --leafsize size Specify the leaf size, the least data item in which btrfs stores data. The default value is the page size. -L, --label name Specify a label for the filesystem. -m, --metadata profile Specify how metadata must be spanned across the devices specified. Valid values are raid0, raid1, raid10 or single. -n, --nodesize size Specify the nodesize. By default the value is set to the pagesize. -s, --sectorsize size Specify the sectorsize, the minimum block allocation. -V, --version Print the mkfs.btrfs version and exit. AVAILABILITY
mkfs.btrfs is part of btrfs-progs. Btrfs is currently under heavy development, and not suitable for any uses other than benchmarking and review. Please refer to the btrfs wiki http://btrfs.wiki.kernel.org for further details. SEE ALSO
