Re: another filesystem as backup
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 must use dev if you want update and security updates, but there is a lot of bugs in those versions. Solaris is not free anymore including security updates after change in rules before one week. Support for ZFS in FreeBSD is marked as experimental, but it depends. So Hammer FS looks like most promising regarding feature on other BSD systems (just my personal tip) ZFS in FreeBSD isn't considered experimental since last september 2009: http://svn.freebsd.org/viewvc/base?view=revisionrevision=197221 So, it's considered production-ready at present.

Re: another filesystem as backup
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 competent btrfs, but it's still mostly in alpha state.

Re: another filesystem as backup
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 and used in the OpenBSD by default. I first wanted to use a file system usable by both OpenBSD and Linux however it looks not very much appropriate. ZFS and HFS seems not very easy to mount on OpenBSD, am I right ? I also could not easily use EXT2 with both Linux and OpenBSD, either one can see and mount not cannot, either the other can do but the first cannot. I might end with the FFS for the backup drive in the end.

Re: another filesystem as backup
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.

Re: another filesystem as backup
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 everything. I love openbsd, but it isn't the right thing all the time either. I hate windows and it is never the right thing, but I'm still forced to use it.
