what are all the advantages of ZFS comparing to UFS SVM

what is the use of creating file system in a file system in ZFS

I can give you two reasons I switched to ZFS over a year ago:
  1. Reliability: ZFS file systems are more reliable in a system crash than UFS. I had a system crash due to a power failure recently. When I powered up the system, it started immediately without fsck.
  2. Ease of configuration/maintenance: With ZFS, creating a mirrored boot drive is as easy as: zfs create mirror c0t0d0 c1t0d0. With UFS SVM, you have to name your metadevices and then create the mirror. With ZFS filesystems, you only need to remember two commands: zpool, zfs

zfs concept
if we create file system with in a file system like zfs create pool/test1/test2 and if we look at df -h it will show all the three that is pool test1 and test2 with same memory size. whats the use of that and what is the concept behind that.


thanks in advance

Sure. But you must remove the disk from the zpool first.

Are you using ZFS ?

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)
