after all statements read here I just want to highlight another issue regarding
ZFS.
It was here many times recommended to set copies=2.
Installing Solaris 10 10/2008 or snv_107 you can choose either to use UFS or
ZFS.
If you choose ZFS by default, the rpool will be created by default with

Good. It looks like this thread can finally die. I received the

I apologize for my poor English. Yes, it's not my mother tongue, but I have no

Dave made a mistake pulling out the drives with out exporting them first.
For sure also UFS/XFS/EXT4/.. doesn't like that kind of operations but only
with ZFS you risk to loose ALL your data.
that's the point!

I did that many times after performing the umount cmd with ufs/reiserfs
I disagree, see posting above.
ZFS just accepts it 2 or 3 times. after that, your data are passed away to
nirvana for no reason.
And it should be legal, to have an external USB drive with a ZFS. with all
respect, why should a user always care for redundancy, e. g. setup a mirror on
a single

If anyone asks questions, they get no actual information, but a huge
amount of blame heaped on the sysadmin. Your post is a great example
of the typical way this problem is handled because it does both: deny
information and blame the sysadmin. Though I'm really picking on you
way too much

You don't move a pool with 'zfs umount', that only unmounts a single zfs
filesystem within a pool, but the pool is still active.. 'zpool export'
releases the pool from the OS, then 'zpool import' on the other machine.

Possibly so. But if you had that ufs/reiserfs on a LVM or on a RAID0
spanning removable drives, you probably wouldn't have been so lucky.

we are not talking about a RAID 5 array or an LVM. We are talking about a
single FS setup as a zpool over the entire available disk space on an
I think you are not reading carefully enough, and I
can trace from your reply a typically American
arrogant behavior.
WE, THE PROUDEST AND infallibles on earth DID NEVER MAKE
a mistake. It is just the stupid user who did not read the
fucking manual carefully enough.
Hello? Did you
if you are interested in my IP Address: no problem:
83.236.164.80
it just exactly approves my assumption, that's best and easier for someone - if
he's in the right position - to adhere a big pavement on someone's mouth to
avoid hearing a legal critique instead of discussing out the problem to
Hi,
after working for 1 month with ZFS on 2 external USB drives I have experienced,
that the all new zfs filesystem is the most unreliable FS I have ever seen.
Since working with the zfs, I have lost datas from:
1 80 GB external Drive
1 1 Terrabyte external Drive
It is a shame, that zfs has
Hi Caspar,
thanks for you reply.
I completely disagreed to your opinion, that is USB. And seems as well, that I
am not the only one having this opinion regarding ZFS.
However, the hardware used is:
1 Sun Fire 280R Solaris 10 generic 10-08 latest updates
1 Lenovo T61 Notebook running Solaris
too many words wasted, but not a single word, how to restore the data.
I have read the man pages carefully. But again: there's nothing said, that on
USB drives zfs umount pool is not allowed.
So how on earth should a simple user know that, if he knows that filesystems
properly unmounted using
Hi,
I have a faulty hard drive on my notebook, but I have all my data stored on an
external USB HDD with a zfs.
Now I want to mount that external zfs hdd on a different notebook running
solaris and supporting zfs as well.
I am unable to do so. If I'd run zpool create, it would wipe out my
RTFM seems to solve many problems ;-)
:# zpool import poolname
