Ext4 vs zfs
 

Hi All,

Today I came across new filesystem in Solaris (ZFS) which has lots of advantage compared to linux filesystem ext4 .Whether Upcoming Btrfs next-gen filesystem for Linux, will replace existing ext3 and ext4 on Linux .Whether its true.Whether its holds all advantage of ZFS.

I heard many saying ZFS had lots of advantage compared to Ext4

Can anyone share what the major disadvantage ZFS compared to ext4

That's wrong. It is not new, and that's, in the context of enterprise storage systems, is probably its biggest advantage over something like BTRFS.

Lots of advantages? That rather depends on the context in which you are using, or intending to use, it and what you are comparing it to. IMHO, for the context in which it is most potentially advantageous, the correct, or most useful, comparison would be between ZFS and LVM plus some variant of EXT or other filesystems.

My current guess is that BTRFS will not replace the EXT file systems, but supplement them. This is, however, a prediction. A guess of some form. I would be interested to know what technical information you can get from such guesses.

You seem to say that there is only one. Of that one, here are two:

• Performance
• Licensing

You would do yourself some favours by reading, eg, the performance testing and other comments that have been published in various tests over at Phoronix.

you can try zfs on linux as a kernel module from here http://zfsonlinux.org/
