We are still talking just about backup/storage. ZFS has a lot of features and it's used for about 4 years or so in production. Hammer FS don't have so much features and is stable for about year. btrfs is for those who want to experiment. Some cons - OpenSolaris has terrible dev process, but you

Hi All, Do you believe it is not a bad idea to use ext2 as a file system for the regular back-up (dumps) of the filesystem ? Actually, I would like to be able to read from a simple Linux the disk that contents the dumps - reaon why. Are there any constraints in doing so ? May you strongly

They aren't available on other platforms. As I know Hammer FS is only on DragonflyBSD, but there is some project to use it under fuse on Linux. ZFS is on Solaris/OpenSolaris, FreeBSD, Mac OS X. There is project to port it to Linux, but don't know about progress. On Linux is only available

Hello, Thanks I will read. My problem is that the disks will be available in RAID1 for system to dump upon, and in case the system itself is not responsive anymore or fails to boot for a hardware reason, I need the external hard drives to be readable by a Linux system. But they will be mounted

There is no way to mount Hammer FS or ZFS in OpenBSD as I know. What's the target you want to achieve? To have some data on RAID accessible from both systems? Then you can use FFS or ext2 as both are of course on OpenBSD and Linux can read FFS. Or you can share it over NFS. On Sun, Feb 21, 2010

What the heck is your business requirement? Nobody runs an OS in prod and expects to use another OS on the same drives. Figure out what you *NEED* rather than what you *WANT* needless complexity is going to kill you. So's going for buzz words. I love zfs but it isn't the right thing for
