I just couldn’t wait any longer, and decided to try something with ZFS. And what do you know? I’ve found a very useful advice from Ben Rockwood, which allows us use regular files created with mkfile as virtual disks for ZFS. VERY useful, especially when you really want to play with such a great technology and maybe try various configurations, but there are no spare physical disks for such experiments.
I will, of course, read and understand all the inner workings of ZFS later, but the first impression of it is this – too easy to be true! 🙂
Here’s what I did:
solaris# mkdir /export/vdev solaris# mkfile 128m /export/vdev/d1 solaris# mkfile 128m /export/vdev/d2 solaris# zpool create try /export/vdev/d1 /export/vdev/d2 solaris# zpool status pool: try state: ONLINE scrub: none requested config: NAME STATE READ WRITE CKSUM try ONLINE 0 0 0 /export/vdev/d1 ONLINE 0 0 0 /export/vdev/d2 ONLINE 0 0 0 solaris# zpool list NAME SIZE USED AVAIL CAP HEALTH ALTROOT try 246M 32,5K 246M 0% ONLINE -
After this the newly made filesystem automatically became available (it’s a partial output of df -k):
Filesystem kbytes used avail capacity Mounted on try 235520 3722 231771 2% /try
Enough for the moment! Now the next challenge will be freeing up one of the two physical disks I’ve got in my Netra t1, so that I could bring it under ZFS control.
